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.

Customer support

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

CUSTOMERHey, I work from home and my internet's been down for about 2 hours now. There's a road crew digging up the street right outside. I already rebooted the gateway twice and checked all the cables. No luck. The internet light is blinking orange. Can you check if this is related to the construction outside? I really need to get back online fast.

AGENTI can help with that. Let's start by verifying your account and checking for any outages in your area. Could you provide me with either your account number or

CUSTOMERYeah, sure, it's BW883017. Sorry, last digit is 1. Can you just check if there's an outage because of the road crew? I really need this sorted quickly.

AGENTI've sent a remote reset to your gateway, and it’s now registered and online. Please give it a couple of minutes for your devices to reconnect. Let me know if everything's back up and running!

CUSTOMERThe internet light just went solid white. How long until my devices actually reconnect? I need to know when I can get back to work. And since I lost 2 hours, can you add a credit for the downtime?

AGENTYour devices should reconnect within the next couple of minutes now that the internet light is solid white.

CUSTOMERGot it.

CUSTOMERTuesday does not work after all because I pick up my daughter. What about Friday? If that is not available, Thursday at 4:10 PM is fine.

Home services

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

CUSTOMERHey, I'm sorry, I'm a little flustered. My baby's crying and I've got water all over the kitchen floor. The pipe under my sink just burst and it's spreading toward a power strip. Can you send someone out right away?

AGENTFirst, let's make sure everyone stays safe. Please unplug the power strip from the wall if it's safe to do so, and keep everyone away from the water and outlets. If you can, turn off the water main to stop the flow. Now, can you give me your phone number or address so I can find your customer information and get someone out to you urgently?

CUSTOMEROkay, thanks for saying that. I'll unplug the power strip right now. All right, it's out. And, uh, how do I turn off the water main? I've never done that before. I'm sorry, I just want to make sure I do this right. My address is 1480 Larkspur Avenue and my phone number is 503-555-0139.

AGENTNo need to apologize,

CUSTOMEROh, okay, so I don't need to mess with the water main. Is it safe to just leave it for now? Sorry, I just want to make sure nothing else gets ruined. So, uh, can you see my info with that address and number?

Insurance

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

CUSTOMERUh, yeah, I think so. I'm at home. My baby's here, so I'm a little flustered, but we're okay. Sorry, is that going to be a problem?

AGENTNo problem at all. I'm glad to hear you're safe, and it's perfectly fine to be flustered after an accident. Is anyone injured, or was anyone hurt in the accident? If so, please call 911 immediately.

CUSTOMERNo, nobody got hurt, thank goodness. Just the cars. Sorry, I should have said that right away. Is that okay?

AGENTThat's perfectly okay. The important thing is that everyone is safe. Let's get started with your claim. Could you please provide your policy number and the policyholder's last name so I can verify your policy?

CUSTOMERUh, sure, let me grab that. The policy number is NG4471903. Oh no, sorry, last one is 2, and the last name is Carter. Is that what you need?

AGENTThank you, I've verified your policy. Now, let's gather some details about the accident. Could you tell me when and where it happened?

CUSTOMERYeah, so, uh, it was about 20 minutes ago at the red light at SE 5th Avenue and Alder Street. Sorry, is that enough for you?

AGENTThat's perfect, thank you. Can you describe what happened during the accident?

CUSTOMERSure. So, uh, I was stopped at the red light and another car just, you know, ran right into the back of mine. I didn't move. He just hit me from behind. Sorry, is that clear enough?

AGENTYes, that's clear. Thank you. Do you have the other driver's name, insurance company, and license plate number?

CUSTOMERYeah, I do. The other driver's name is Kevin Lund. He's insured with Pacific Shore. License plate is 7KX, like x-ray, R214. Is that all right?

AGENTThat's great, thank you. Did the police attend the scene, and if so, was there a report number provided?

CUSTOMERNo, the police didn't come. We just handled it ourselves.

CUSTOMERSorry, is that going to cause any issues?

AGENTNo worries, it won't cause any issues. We can proceed without a police report. Lastly, is your vehicle safe to drive, or do you need a tow?

CUSTOMEROh no, I can't drive it. The back bumper's crushed and the rear wheel's rubbing pretty bad. Uh, can you send a tow truck? And, um, where will the car be taken?

AGENTI've arranged for a tow truck from Eastside Towing. They should arrive in about 45 minutes and will take your vehicle to a Northgate partner repair shop at 9th and Morrison. Your claim number is NGM-904417, and your case will be handled by adjuster Priya Shah. She'll contact you within one business day. Just to confirm, your policy number is NG4471902 and the other driver's license plate is 7KXR214. Is everything correct?

CUSTOMERYeah, that all sounds right. Can I just double-check? My claim number is NGM-904417, and the adjuster's Priya Shah? Sorry, I just want to make sure nothing gets lost. Also, um, I'm a little worried. How much do I have to pay for all this? And since he hit me, I shouldn't have to pay a deductible, right?

AGENTYes, your claim number is indeed NGM-904417, and Priya Shah will be your adjuster. Regarding the coverage, you have a collision deductible of $500. Your policy also includes rental reimbursement at $40 per day for up to 30 days starting today, and towing is covered up to 25 miles, which should cover the tow to our partner repair shop. If the other driver is found at fault, you may be able to recover the deductible, but your adjuster will help you with that process. If you have any more questions or need further assistance, feel free to ask.

CUSTOMERThanks for confirming all that, but, um, I just want to be sure. He hit me, so I really shouldn't have to pay that deductible, right? And, uh, will my premium go up because of this? Sorry, I'm just nervous about all the costs. Also, do I just wait here for the tow truck now?

AGENTI understand your concerns. If the other driver is found to be at fault, you may not have to pay the deductible, and our adjuster, Priya Shah, will work with you to recover it. As for your premium, it typically depends on the details and findings of the claim. Priya will also be able to provide more specific guidance on that once she reviews everything. For now, just wait for the tow truck to arrive. They should be there in about 45 minutes. If you have any other questions or need more assistance, feel free to reach out. Stay safe, and let us know if there's anything else we can do for you.

CUSTOMERAll right, uh, thank you for all your help. I'll wait for the tow truck and talk to Priya about the deductible and premium. I appreciate you answering my questions. Goodbye.

AGENTYou're very welcome. If you have any more questions later, don't hesitate to reach out. Take care, and goodbye!
