Real-time voice chat and text-to-speech studio with voice selection, credit billing, and audio download
About Dessa AI
Dessa AI is an independent voice tool studio offering two capabilities: Live Talk real-time voice conversation and Text to Speech text-to-speech. Users pick a voice, review the credit cost, and only then start the task, and the audio can be downloaded as WAV. Live Talk is billed 1 credit per 6 seconds, rounded up; at least 3 available credits are required before connecting, credits are reserved before the session, and unused credits are refunded once the server confirms settlement; text to speech is billed 1 credit per 160 characters after trimming leading and trailing whitespace, rounded up. After email verification each account gets 20 free credits, once per account. Official pricing is mainly monthly subscriptions: Starter $19.9/month, Pro $39.9/month, Max $79.9/month.
