Cartesia
Low-latency speech models and voice agents for developers
Which one is for you
Pick Cartesia if
- Fits if you're building a voice agent or phone bot through an API
- Works for developers who want speech and transcription from one API
Look elsewhere if
- Not for you if you don't write code, or want a voiceover editor or a phone app
- Skip it if you hoped to go live on the free plan, which has no commercial use license
- Tight if you leave overages off, since requests stop when credits run out
- Watch out: overages run $65 per million credits on Pro, and agent calls cost $0.03 a minute plus $0.014 on a Cartesia number
- Pricey if you need a professional voice clone, which starts on the $49 Startup plan
Pick Deepdub if
- Fits if you localize films, series or broadcasts and can talk to sales
- Makes sense if you are adding expressive speech to a voice agent through the API
Look elsewhere if
- Not for you if you want a price before you talk to anyone, because none is published
- Skip it if you are an individual creator, as the trial wants a business email
- Tight if you need more than 10 minutes to judge it, since the trial stops at 10,000 characters
- Watch out: the site's emphasis has moved toward voice agents and enterprise media work, away from self-serve dubbing
How we grade them
| 2.4GPACartesiaFair | 2.0GPADeepdubFair | |
|---|---|---|
| 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 that plan, which is less than its alternatives charge for the same amount. Overages cost $65 per million credits on Pro. | CNo prices published. After the trial, access is through time-based packages and sales, so there is nothing to compare against the category's $5 to $19 range. |
| Free plan and trial | C20,000 credits a month, about 27 minutes of speech, plus $1 of agent usage. Enough to try it, but there's no commercial use license, so nothing built on it can go live. | CA 14-day trial with up to 10,000 characters, roughly 10 minutes. Sign-up wants a business email, and whether a card is needed isn't stated. |
| 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. | CDubbing handled by a production team, a TTS and speech-to-speech API with 1,000+ licensed voices, cloning, live dubbing and voice for agents. Broad, but much of it is a service rather than a tool you run yourself. |
| 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. Dubbing goes through a team and the API is documented for developers, so nobody is productive in five minutes. |
| 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 and an API. No integrations are listed, and no apps. |
| Best for | speech through an API for voice agents | studio dubbing and a voice API, quoted by sales |

Worth knowing
Cartesia

- Voice agent calls cost $0.03 a minute from the plan's prepaid dollars, plus $0.014 a minute on a Cartesia phone number.
Deepdub
- No prices are published; after the trial, access is through time-based packages and sales.
- The free trial covers 10,000 characters, roughly 10 minutes of audio, for 14 days.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
