How this service works
Premium natural speech with Deepgram Aura-2: 40 English voices (luna, orion, athena, zeus...) and Spanish, returned as MP3 (or base64 JSON). $0.002 plus $0.07 per 1,000 characters, minimum $0.005. Add store=true (+$0.001) to get a 7-day share link instead of the data inline.
Output
Returns either a binary MP3 audio file or a JSON object containing base64-encoded audio data. If the store option is enabled, also returns a 7-day shareable link to the generated audio file.
Example use cases
Podcast intro voiceover generation
“Turn this script into spoken audio using the 'orion' voice in English and return an MP3: 'Welcome back to The Daily Brief, your source for the top stories shaping the world today.'”
Spanish customer support message
“Convert this customer service message to speech in Spanish using the 'luna' voice and give me an MP3: 'Hola, gracias por contactar con nuestro equipo. Estamos aquí para ayudarte.'”
Shareable audio snippet for social
“Synthesize this text with the 'zeus' voice in English, return it as a 7-day share link so I can post it: 'The future of AI is here, and it is speaking to you right now.'”
