How we grade them
| 2.4GPACartesiaFair | 2.0GPARespeecherFair | |
|---|---|---|
| Value for money | BPro is $5 a month for 100,000 credits, about 133 minutes of speech, with a commercial license, instant cloning and $5 of agent calls. An hour a month fits on the cheapest paid plan, which undercuts its alternatives for the same amount. | CPay-as-you-go packs are $5 per 20,000 characters, commercial use included, and Respeecher puts 60,000 characters at about an hour, so an hour is $15. Subscriptions run from $18 for 30,000 characters to Creator at $74 a month billed yearly. The real-time API is $2 per 60,000 characters. |
| Free plan and trial | C20,000 credits a month, about 27 minutes of speech, plus $1 of agent usage. Plenty for testing, but there's no commercial use license, so nothing built on it can go live. | CNo free plan. There's a free trial of text to speech and speech-to-speech in the Marketplace, but the listing doesn't say how much it covers or whether it wants a card. The real-time API is free to start. |
| Features | CStreaming text to speech in dozens of languages, streaming transcription, instant and professional cloning, and voice agents with phone numbers. It does the developer job fully, but that's a narrower job: there's no voiceover editor, as the listing says. | CSpeech-to-speech, licensed celebrity voices, a Pro Tools plugin and a real-time API, which few here offer. But custom voices and real-time conversion are Enterprise-only, subscriptions get 25+ voices, and Creator allows 100 requests a day. |
| Ease of use | CNo store rating on record. It's built for developers: you call it from code with the Python or JavaScript SDK, or try voices in a web playground. Fine if you code, slow going if you don't. | CNo store rating on record. The Marketplace is a web app with a Pro Tools plugin, and speech-to-speech means recording your own takes. Custom voice work runs through Respeecher's team, not a sign-up. |
| Platforms and integrations | BWeb and an API with regional endpoints, plus LiveKit, Pipecat, Rasa and Genesys for voice agents, and on-premise setups through sales. No phone or desktop app. | CWeb only, with an API and one plugin, for Pro Tools. That's the right plugin for sound studios, but it's the whole list, and there's no phone or desktop app. |
| Best for | fast speech for developers' voice agents | recreating a particular voice for film and games |

Worth knowing
Cartesia
- Cartesia is a developer platform: you use it through the API or a web playground, and there is no voiceover editor or mobile app.
- The Free plan has no commercial use license; it starts on Pro, which also adds instant cloning. Professional cloning needs Startup or above.
- Paid plans can go past their credits at $65 per million on Pro, $45 on Startup and $38 on Scale; with overages off, requests are blocked.
- Voice agent calls cost $0.06 a minute from the plan's prepaid dollars, plus $0.014 a minute on a Cartesia phone number.
Respeecher
- Custom voices and real-time voice conversion are Enterprise-only, and cloning someone's voice needs a signed agreement with that person.
- Pay-as-you-go packs, from $5 for 20,000 characters or 5 minutes of speech-to-speech to $250 for 500 credits, include commercial usage rights but no API access.
- The real-time TTS API is billed separately at $2 per 60,000 characters, about an hour of speech.
- Subscriptions cap daily text-to-speech requests: 350 on TTS only, 100 on Creator and 500 on Power.
Key features
Cartesia
- Sonic text to speech
- A streaming text-to-speech model built for live conversation, with dozens of languages and regional accents. One minute of audio uses about 750 to 800 credits.
- Ink speech to text
- A streaming transcription model with its own concurrency pool, so heavy transcription does not slow text to speech.
- Voice cloning
- Instant clones from 10 seconds of audio start on Pro; Professional clones start on Startup. Cartesia says to clone only your own voice or one you have explicit permission to use.
- Managed Agents
- Build voice agents that answer and make phone calls, with Cartesia-provided phone numbers, from 1 on Free to 10 on Scale.
- Deployment options
- Call the models through regional API endpoints with Python and JavaScript SDKs, or arrange on-premise, private cloud or on-device deployment with sales.
Respeecher
- Custom voice cloning for productions
- Respeecher recreates or replicates a specific voice for film, TV, games and ads, working with the production team. Its case studies include a younger Luke Skywalker's voice for The Mandalorian.
- Speech-to-speech
- Record or upload a line in your own voice and convert it into another voice. Creator and Power include monthly speech-to-speech minutes; TTS only does not.
- Voice Marketplace
- A self-serve library of AI voices, including licensed celebrity voices, for text to speech and speech-to-speech, with a plugin for Pro Tools.
- Real-time TTS API
- Respeecher Space is a low-latency text-to-speech API for voice agents, billed by usage and free to start.
- Consent-based voices
- Respeecher says every voice replication needs explicit permission from the voice owner through a mutually signed agreement, and Marketplace celebrity voices are licensed and moderated.
