Questions
What Dessa AI costs, how your data is handled and what happens when something fails.
Dessa AI is a voice studio you use in the browser on a computer or phone. It has two main tools: Live Talk, a real-time spoken conversation with an AI voice, and Text to Speech, which turns a written script into a WAV file.
Common uses of Dessa AI include speaking practice in another language, rehearsing for job interviews and talking through an idea out loud. Creators use Dessa AI Text to Speech for video narration, course audio, podcast intros and ad reads.
Dessa AI has no free plan. You pay with credits from a subscription or a credit pack. Live Talk uses 10 credits per minute, counted every 6 seconds, with a 15-second minimum per call. A web search during a call uses 2 credits. Text to Speech uses 1 credit per 160 characters. Subscription credits renew monthly and lapse at the end of the month, while pack credits never expire.
Dessa AI is an independent studio and is not run by Block, the maker of the Dessa voice model. That model has no public API yet, so Dessa AI does not run on it today: Live Talk uses GPT-Live-1, and Text to Speech and voice cloning use HeyGen Voice. If the API opens, we plan to add it to Dessa AI.
Yes. Speech made with paid credits can go into commercial work such as YouTube videos, podcasts, courses and ads, and it has no watermark. You are responsible for your script, and you may not use Dessa AI to impersonate a real person.
Your microphone streams only while a Dessa AI call is active, and recordings of calls are not kept. Captions stay in your browser tab and are gone when you leave. Text to Speech files are private to your account, and you can delete them whenever you want.
Live Talk offers 22 voices, and a call lasts up to 20 to 90 minutes depending on your plan. Text to Speech offers 24 voices, detects 39 languages from your script and accepts 2,000 to 5,000 characters per script. Dessa AI exports speech as 44.1 kHz WAV.
No. When a call cannot connect or a script fails to generate, Dessa AI returns the credits automatically. Calls are charged in 30-second blocks ahead of use, and any time left unused goes back to your balance when the call ends.
