Roark Live Bench · Suite v1.3 · Sweep of 30 October 2026

Voice AI models, ranked on live phone calls.

Every speech-to-text, language model and text-to-speech model, run in every combination on the same real call to the same agent. A model is ranked on every stack it runs in; the stacks are the evidence.

The read

  • 430 of 642 cascades complete the task in at least 90% of calls, and the top 10 sit within 1 point of each other. What separates the top stacks is speed and cost.
  • Median response time runs from 2.0 s to 6.2 s on the same agent and the same caller, a spread of 4.2 s that comes entirely from the models behind it.
  • No stack wins everything. The fastest, Speechmatics Linden-1 (own VAD) + Anthropic Claude Haiku 4.5 + ElevenLabs Turbo v2.5 at 2.0 s, ranks 559 of 642 on task completion; the most complete is Speechmatics Linden-1 (own VAD) + OpenAI GPT-6.1 Sol + OpenAI TTS-1 HD at 99%.
  • The language model matters most: swapping it moves task completion by 7 points, against 3 for the speech engine and 2 for the transcriber.
  • The fastest speech-to-speech model answers 0.1 s sooner than the fastest cascade, and its completion rate sits 12 points below the best cascade.

Cascade vs Speech-to-Speech

The first choice to make. A cascade chains three models: one transcribes, one decides what to say, one speaks. A speech-to-speech model does all three at once. Both run the same agent on the same calls here.

  • Cascades lead on task completion, tool use, time to first word, barge-in handling and cost per task; speech-to-speech leads on response time. Neither wins outright, so the right choice depends on what your calls need.
  • Speech-to-speech costs 1.6 times as much per completed task: $0.24 for speech-to-speech against $0.15 for cascades.
  • The biggest difference is response time: 3.8 s for cascades against 2.1 s for speech-to-speech.

The three strongest of each, averaged. Cascades: AssemblyAI Universal-3.6 Pro + OpenAI GPT-6.1 Sol + Rime Coda; Speechmatics Linden-1 (own VAD) + OpenAI GPT-4.1 + Rime Coda; AssemblyAI Universal-3.6 Pro + Google Gemini 3.8 Flash + Rime Coda. Speech-to-speech: grok-voice-think-fast-2.0; gpt-live-1 (backend gpt-6-luna); grok-voice-3.0. Each measure is scored 0 to 100 on its own scale, further out is better; the table gives the same figures in their own units.

Which to use

  • Choose speech-to-speech when the pause matters more than the outcome: short transactional calls, callers who interrupt, queues where every half second costs you callers. Expect to pay more, and choose the model carefully (grok-voice-3.0 leads here).
  • Choose a cascade when the call has to complete, when cost matters, or when you need to see which stage to fix. It is 12 points ahead on task completion here.
  • Costs are what each stack’s providers charged for these calls, at the rates in effect when they ran. Telephony and hosting are not included.

Speech-to-Text

The transcriber turns the caller's speech into text. It decides what the agent thinks it heard, and nothing after it can start until it finishes.

  • AssemblyAI Universal-3.6 Pro, AssemblyAI Universal-3.5 Pro, Deepgram Nova-3 and Speechmatics Enhanced (realtime) are level: none leads by more than the margin of error. Of them, AssemblyAI Universal-3.6 Pro costs least, at $0.030 a call. Avoid Speechmatics Linden-1 (own VAD): last on semantic word error rate (2.2%).
  • Speechmatics Linden-1 (own VAD) delivers its transcript in 0.49 s, OpenAI Whisper-1 in 1.93 s: 1.44 s added to every turn of the call.
  • AssemblyAI Universal-3.6 Pro is the most accurate: it changes the meaning of 0.9% of the caller's words, against 2.2% for Speechmatics Linden-1 (own VAD).
  • In 341 of 648 cascades the transcriber is the slowest step of the turn, whichever model runs it.

Language model

The language model decides what the agent says and does. It has the most influence on whether the task gets done, and usually takes the largest share of each turn.

  • Pick OpenAI GPT-6.1 Sol: it leads on task completion (95%), tool use (77%) and instruction following (4.2 / 5). If speed matters more, Anthropic Claude Haiku 4.5 is the quickest, at 0.36 s, and completes 91%. Avoid OpenAI GPT-4o: last on task completion (88%).
  • Anthropic Claude Haiku 4.5 starts answering in 0.36 s, Google Gemini 3.8 Flash in 1.47 s: 1.11 s added to every turn of the call.
  • OpenAI GPT-6.1 Sol uses its tools most reliably: it handles its tools without a mistake on 77% of calls, against 38% for OpenAI GPT-5.1.
  • In 161 of 648 cascades the language model is the slowest step of the turn, whichever model runs it.

Text-to-Speech

The speech engine is the voice the caller hears, and the last step before they hear anything.

  • Cartesia Sonic-3.6, ElevenLabs v4 Turbo and Cartesia Sonic-3.5 are level: none leads by more than the margin of error. Of them, Cartesia Sonic-3.5 costs least, at $0.165 a call. Avoid OpenAI TTS-1 HD: last on readback accuracy (80%), word error rate (8.7%) and time to first audio byte (2.09 s).
  • ElevenLabs v4 Turbo starts speaking in 0.11 s, OpenAI TTS-1 HD in 2.09 s: 1.97 s added to every turn of the call.
  • Cartesia Sonic-3.6 is the most accurate: it reads codes, amounts and dates back correctly 87% of the time, against 80% for OpenAI TTS-1 HD.
  • Cartesia Sonic-3.6 sounds the most human: 3.8 / 5, against 3.4 / 5 for ElevenLabs Flash v2.5.
  • In 99 of 648 cascades the speech engine is the slowest step of the turn, most often with OpenAI TTS-1 HD (54 of them).

Speech-to-Speech models

One model listens, reasons and speaks, so there is nothing to swap and no stages to split. Each is judged on the whole call, with the same calls and the same scoring as every cascade.

  • The model matters as much as the architecture: xAI Grok Voice 3.0 completes 87% of tasks, ElevenLabs Realtime v1 Mini 42%.
  • xAI Grok Voice 3.0 answers in 1.9 s against 4.2 s for Google Gemini 2.5 Flash native audio.
  • Price varies as much as quality: $0.06 per completed task for Amazon Nova 2 Sonic, $0.69 for OpenAI GPT Realtime 2.

Every stack

The evidence behind the model boards: each combination on its own calls, scored on the same recipe. Open a stack for its full report, every figure it was scored on and the calls behind them.

Roark score, top 15

Whiskers show the 95% interval. The shaded stacks tie for first: these calls cannot separate them.

Each score carries its 95% margin of error. A rank is the best place a stack could hold once every margin is allowed for, so stacks the calls cannot tell apart share one and are listed by the low end of their margin; hover a rank for the worst place it could hold. 85 stacks are level with the leader: their calls cannot tell them apart.

Loading every stack

By industry

Each industry ranked on its own calls: the same five callers, its own tasks and tools. A stack has a handful of calls in each, so a cascade is ranked on what its transcriber, language model and voice show across every stack in that industry, and a speech-to-speech model on its own calls there. Pairings show on the main board. Each row reads across: the main board's figure first, then every industry's on the same figure.

No stack matches these filters.

No stack matches

Each industry column is that industry's own board, every row it ranks. A dash is a row the industry does not rank on this figure; the arrow beside an industry opens its full board.

How it works

Every number on this page comes from real phone calls, placed and scored the same way for every stack.

01

Real calls, four industries, five callers

Roark places real phone calls over the public phone network to a reference agent for each of four industries: rescheduling a clinic appointment, booking an urgent home repair, opening an auto insurance claim and fixing an internet outage. Each agent has its own prompt and tools, identical for every stack. The tasks carry the details real calls trip on: a corrected date of birth, a policy number spelled out, a constraint added halfway through.

Every industry is called by the same five simulated callers: a quiet US English line, a Spanish-accented caller on a city street, an Indian English caller in a busy café, a flustered Southern caller with a baby crying, and a fast caller who interrupts over construction noise. They are equally clear about what they want, so a call fails because of the agent, not the caller. Only the models change, so any difference on the board comes from them.

Each caller rings each industry once for a cascade and four times for a speech-to-speech model. A cascade's figures also draw on its parts, heard in dozens of other stacks; a speech-to-speech model has only its own calls, so it takes more of them.

That makes industries comparable over the same callers, and callers over the same tasks, and the board can be re-ranked by either. One caller within one industry is too few calls to judge, so the board never shows it.

Every model, in every combination

9 transcribers, 8 language models and 9 voices are run in every combination with each other, beside 14 speech-to-speech models. A model's own figures pool every stack it runs in, adjusted for its partners in each one, so every model is compared as if it ran with the same partners. A transcriber's figure rests on hundreds of calls with every language model and every voice, not on one lucky pairing.

That measures a model where it actually works: inside a running agent, on live phone audio, through interruptions, corrections and real turn-taking. A test that feeds a model clean audio files or one prompt at a time never sees any of that.

03

One score, weighted by what matters on a call

Each section ranks on a Roark score. Every figure scores 0 to 100 between two published points: full marks where doing better makes no difference to the caller, zero where the call breaks down. Each then counts at its weight, and the weights follow one order everywhere: whether the caller got what they rang for, then whether the agent got it right, then speed.

A stack, cascade or speech-to-speech, is scored on the outcome and the reply first, then on what each of its components got right on its own calls: the words its transcriber got wrong in a way that changes the meaning, whether its voice read codes and amounts back right and kept one steady voice, and whether its tools were handled. How human a voice sounds is shown on the boards and not scored. A component that leads its section lifts every stack that carries it, by the same recipe for every stack. A figure a stack cannot carry, such as a semantic word error rate for a speech-to-speech model with no transcript, is credited at the field median, so the stack is neither flattered nor punished for it.

On a full sweep each cascade's figure is 25% what its own calls measured and 75% what every other stack shows about its transcriber, language model and voice, fitted across the whole sweep. The split is the same for every stack, so a lucky run does not lead and a stack's score does not move with how noisy its calls were. In an industry a stack has a handful of calls, so a cascade's figure there is what its transcriber, language model and voice show across every stack in that industry's calls, and a speech-to-speech model's is its own calls there. How a particular pairing beats or misses its parts shows on the main board, where each stack has all of its calls. The best overall, best value and best speech-to-speech picks, and the best stack in each industry, are each the one whose score is highest at the low end of its margin of error, so a few lucky calls cannot carry a stack past one whose score rests on hundreds. Stacks that share a rank are listed by score, so the pick can sit below a higher score it cannot be told from, and its reason says how many stacks are level with it.

That order comes from real-world voice agent calls, where getting the conversation right predicts how a call ends more strongly than speed does. The latency points come from the same calls: replying faster than about 2 seconds made no measurable difference, and calls went measurably worse once the agent took more than about 3 seconds to reply.

In an industry a stack has a handful of calls, so a cascade's figure there is what its transcriber, language model and voice show across every stack in that industry's calls, and a speech-to-speech model's is its own calls there.

Factor in price and cost takes 25% of the score; the other weights keep their proportions. Price is scored on a log scale, so each doubling costs the same points.

A figure listed as shown, not scored is on the section’s boards and outside its score. Where a section has not collected a scored figure yet, the others share its weight.

Every call recorded and judged

Every call is recorded. Judge models score each transcript for the outcome and the conversation, and the timings come from the recording. Every figure links to the calls behind it.

Roark is on both sides of every call: it plays the caller, so it keeps the exact text its caller said, and it runs the agent under test, so it sees what the agent’s transcriber heard and what its model wrote for its voice. The transcript and voice figures come from lining those up, with no hand-made transcript in between. Each carries a margin from the synthetic voice or Roark’s transcriber in the loop. Every model faces the same ones under the same conditions, so the figures compare models on the same calls through the same voice and the same ear, though those slips need not fall evenly on each model. The rates will not match a vendor’s figure on a curated set; read them against each other.

AGENTBrightwave Internet support, this is Alex. What’s going on with your service?

CUSTOMERHi. Yeah. I'm calling because my has been down for about two hours now. It was almost... And the road crew digging up the outside. So you know, I'm wondering if that's the cause. I already rebooted my gateway twice. Checked every cable, but the unit light is blinking orange. Can you check happening?

AGENTI can definitely check what’s going on. First, I need to pull

CUSTOMERMhmm. Sure. Go ahead.

AGENTI’ve got your account pulled up under ID BW-883011. There’s no area outage showing for your address. I ran a line test, and your signal to the gateway looks good, but the gateway just wasn’t registered properly. I’ve pushed a remote reset to your Brightwave BX7, and it’s now showing as registered and online on my side. The lights you should see: - Power: solid. - Internet/Globe: solid white. - Wi‑Fi: solid or blinking white (normal traffic). It can take about 2 minutes for your devices to reconnect. When you get a moment, try: 1. Checking if that orange light has gone solid white. 2. Testing a device

CUSTOMERYes.

CUSTOMERAlright. How long did it usually take for a thing to reconnect? Is it just a couple of minutes, or should I wait longer?

AGENTYou should be back up in about 2–3 minutes in most cases.

CUSTOMERK. Got it. So, since almost two hours of work, is there a way I can get a credit for the downtime?

AGENTYes, I can help with that. I’ve added a $10.00 service credit to your account BW-883011 for the downtime. You’ll see it on your next bill. Before we wrap up, is everything online and working normally now on your end?

CUSTOMEREverything looks good. Listen. I lost two hours of work. You need more than $10.

AGENTI hear you—losing two hours of work is brutal, especially when you rely on the connection. On my side, the system already approved a $10.00 credit on account BW-883011, which will show on your next bill.

CUSTOMEROkay. Thanks for checking. Goodbye.

AGENTUnderstood. For reference, you’ve got a $10.00 credit on account BW-883011 that will show on your next bill. Thanks for calling Brightwave, and I’m glad your connection’s back up. Goodbye.

Home services

AGENTCopperline Home Services, this is Alex. What can I help you with?

CUSTOMERHi. I've got an emergency. A pipe under my kitchen sink just burst and water's spreading across the floor toward a power strip. I haven't shut the water off yet. Can you help?

AGENTYes, I can help. First, let’s keep you safe

CUSTOMERGreat.

CUSTOMERRight. What should I do to shut the water off?

AGENTGo step by step, and stay clear of that power strip as much as you can. 1. Stay safe around electricity. - If you can safely reach the power strip without stepping in water, unplug it now. - If there is already water around it or you’d have to stand in water to reach it, do not touch it. - If the water is already at the outlets or the power strip is sparking, tell me right away and, if possible, turn off power to the kitchen at your breaker panel (I can walk you through that next). 2. Try to shut off

CUSTOMERThere's water getting close, but it hasn't reached the outlets yet. I can't safely unplug the power strip without stepping in water. What's the best way to turn off the power to the kitchen?

AGENTUnderstood—stay out of the water and away from that power strip. Let’s kill power first,

CUSTOMERGot it.

CUSTOMERHow do I turn off the power to the kitchen? Which breaker should I look for?

AGENTHead to your breaker panel now, and stay out of the water in the kitchen. 1. Open the breaker panel door. - It’s usually in a basement, garage, utility room, or hallway. 2.

CUSTOMERAlright.

CUSTOMEROkay. I'm at the breaker panel. What should I do next?

AGENTGood. Stay there and keep everyone out of the kitchen for now. 1. Look at the breaker labels. - Many panels have a list or handwritten labels next to each switch. - Look for anything like: - “Kitchen”. - -

CUSTOMERAlright.

AGENTGood.

CUSTOMERYeah. Yeah. Right. What do I do once I find the kitchen breaker?

AGENTOnce you’ve found the kitchen breaker: 1. Turn the kitchen breaker OFF. - The switch will be either: -

CUSTOMEROkay. I found the kitchen breaker. I'm turning it off now.

AGENTGood. Flip it fully to OFF and leave it there. Next, let’s stop the water. 1. Under-sink shutoff (fastest if it works). - Go back to the kitchen, but do not touch the power strip or any outlets. - Open the cabinet under the sink. - You should see one or two small valves on the pipes (usually with small round or oval handles, or little levers). - Turn each valve clockwise (right) until it stops. That should shut off water to the faucet. 2. If there are no valves there, or they won’t turn: - We’ll need to shut off the main water to the house. - Before we do that: can you tell me if you see those small shutoff valves under the sink, and if you’re able to turn them?

CUSTOMERYes. I see two small valves under the sink, and I'm able to turn them both clockwise. The water has stopped.

AGENTGood—nice job. With the water stopped and the kitchen power off, you’ve taken care of the most urgent safety issues. I’d like to get a plumber out to you as soon as possible to repair the burst pipe and check for any water damage. First, a couple quick safety

CUSTOMERSure. Go ahead.

AGENTThanks. Since the water is off and the kitchen circuit is off, you’re in a safe spot for now. Next steps for you:

CUSTOMERRight.

CUSTOMEROkay. What should I do next?

AGENTYou’ve done the most important parts already. Here’s what to do next, and then I’d like to get you on our schedule. 1. Stay safe around water and electricity. - Keep the kitchen breaker OFF and don’t use outlets in that area until a tech has checked things. - Keep people, pets, and electronics away from the wet area. 2. Limit water damage. - Put down towels or a mop to soak up standing water, especially near cabinets and baseboards. - If you have a fan, you can set it to blow across the floor (but only if it’s plugged into a dry, safe outlet in another room, with the cord kept out of any wet areas). 3. Don’t use the sink. - Avoid turning that

CUSTOMERGot it.

CUSTOMERIt. Right. I won't use the sink or turn the water back on. Can you let me know how soon someone can come out and how much the visit will cost?

Insurance

AGENTNorthgate Mutual claims, this is Alex. Are you somewhere safe right now?

CUSTOMERYes. I am safe. I am standing next to my car, on the sidewalk. Nobody is hurt.

AGENTI’m glad to hear everyone’s okay and that you’re in a safe spot. Let’s get your claim started. I’ll first look up your policy. 1. What is your auto policy number? 2. And the policyholder’s last name, as it appears on the policy?

CUSTOMERMhmm. My policy number is ND4471903. Oh, sorry. Last one is 2, and my last name is Ramirez.

AGENTThanks, Mr./Ms. Ramirez. I’ve found your policy ending in 1902 under the name Ramirez for a 2021 Honda CR‑V. Next, I need a few details about the accident so we can open the claim: 1. When did the accident happen? 2. Where did it happen? 3. Can you tell me what happened, in your own words? 4. Is your Honda CR‑V drivable, or does it feel unsafe to drive?

CUSTOMERYes. The accident happened about twenty minutes ago. I was stopped at a red light at S E 5th Avenue and Alders Street. Another car hit the back of my car. The back bumper is crushed. And the rear wheel rubs so I cannot drive it. It feels unsafe.

AGENTThank you, that’s helpful, and I’m glad you’re not hurt. Because the car feels unsafe to drive and the rear wheel is

CUSTOMERYeah. That's right. The rear wheel is rubbing, so, I really can't drive it.

AGENTThanks for confirming that. We’ll keep you off the road. I’ve done two things for you: 1) Tow truck. - I’ve dispatched a tow to: the intersection of SE 5th Avenue and Alders Street. - Tow company: Eastside Towing. - Estimated arrival: about 45 minutes. - They’ll take your car to our Northgate partner repair shop at 9th and Morrison. 2) Claim opened. - Your verified policy number is: ND4471902. - I’ve opened a claim for you. Your claim number is: NGM-904417. - The assigned adjuster is Priya Shah. You should hear from her within one business day. A couple of quick follow‑up

CUSTOMEROkay.

AGENTI’ll keep this quick so you can focus on the scene. First, I want to read a few key details back to you: - Policy number I have: ND4471902. - Claim number I’ve opened: NGM-904417. Please let me know if either of those is not correct. Next, I still need a couple of details for the claim file: 1. Other driver

CUSTOMERYes. The other driver is Kevin Lund. He's insured with Pacific Shore. Plate number is 7KX like x-ray, R21. Four.

AGENTThank you, I’ve added that to your claim. Let me read it back to be sure I have it right: - Other driver’s name: Kevin Lund - Other driver’s insurer: Pacific Shore - Other vehicle license plate: 7 K X R 2

CUSTOMERYes. That's right. 7KX like X-ray, R214

AGENTGot it, thank you for confirming: the other vehicle’s plate is 7KXR214. I’ve saved it exactly that way on your claim. Here’s what we have on file now, just to recap the key

CUSTOMEROkay. Go ahead.

AGENTHere’s what I have on your claim so far: - Policy number: ND4471902. - Vehicle: 2021 Honda CR‑V. - Claim number: NGM-904417. Accident details: - When: About 20 minutes ago (today). - Where: Intersection of SE 5th Avenue and Alders Street. - What happened: You were stopped at a red light and were rear‑ended. Rear bumper is crushed and the rear wheel is rubbing, so the vehicle is not drivable. - Injuries: None reported. - Police: You haven’t mentioned officers on scene or a report so far. Other driver: - Name: Kevin Lund. - Insurer: Pacific Shore. - License plate: 7KXR214. Tow: - Tow company: Eastside Towing. - Dispatched to: SE 5th Avenue and Alders Street. - Destination: Northgate partner repair shop at 9th and Morrison. - ETA: About 45 minutes from dispatch. Two quick questions to finish the intake: 1) Did the police come to the scene, and if so, do you have a report number? 2) Do you have any immediate questions about what happens next with the claim or your car?

CUSTOMEROh, yes. So I have a couple questions. How much do I have to pay? Is there a deductible for this? And, since you hit me, I should not have to pay that. Right? Also, do I get a rental car? And is my premium going to go up?

AGENTI’ll walk through each of those for you, based only on what I can see on your policy. Here’s what your policy shows: 1) Deductible / what you might pay. - Your collision deductible is: $500. - In a rear‑end situation where the other driver is at fault, the usual path is: - You can go through Kevin Lund’s insurer (Pacific Shore). If they accept fault and handle the repairs directly, you typically would not pay your collision deductible to Northgate. - If you choose to go through your own policy for faster repairs, your $500 collision deductible would apply up front. - If we later recover the money from Pacific Shore, your deductible may be reimbursed. The adjuster will walk you through which route makes the most sense. I can’t decide fault or guarantee reimbursement myself, but your adjuster,

CUSTOMEROkay. So if Pacific Shore agrees, I don't pay the deductible. But if I go to my own policy, I pay $500 now, and maybe get it back later. Got it.

AGENTYou’ve got it exactly right. - If Pacific Shore accepts liability and handles the claim directly: you generally would not pay your $500 collision deductible. - If you go through your Northgate policy: the $500 deductible applies now, and if Northgate later recovers from Pacific Shore, your deductible may be reimbursed. A couple of quick

CUSTOMERAlright.

CUSTOMERCool then. And about the rental car, do I get one while my car is being repaired? Also, will my premium go up because of this?

AGENTHere’s what I can see on your policy and what I can’t see: 1) Rental car. Your policy includes rental coverage for: -

CUSTOMEROkay. So I do have rental coverage. Good. And, do you know if my premium will increase, or do I have to wait for the adjuster?

AGENTOn the premium question, that’s something I can’t see or decide from here. Whether your premium changes depends on things like: - Who is found at fault. - The final outcome of the claim. - Your prior driving/claims history. - Northgate’s rating rules at renewal time. I don’t have access to rating or pricing systems, so I can’t tell you if, or by how much, your premium might change. Your adjuster, Priya Shah, can explain how the claim is being evaluated and, if needed, can connect you with someone who can talk through possible premium impacts at renewal. For now, your next steps are: - Wait for the tow and get the car to the shop. - Talk with Priya (you’ll hear from her within one business day) about: - Whether to go through Pacific Shore or your own policy. - Setting up the rental under your rental coverage. - Any concerns about potential premium changes. Before we wrap up, do you have any other questions about what happens in the next day or two?

CUSTOMERAlright. No. That's covers everything I needed. Thank you for your help. Goodbye.
