Text-to-speech (OpenAI-compatible /v1/audio/speech). 4,358 voices across 9 providers (KokoroTTS, AWS Polly, Azure, MiniMax, more — free catalog at GET /v1/audio/voices). Returns mp3. Up to 3000 chars. $0.000006 USDC per character (Telnyx list rate, zero margin): pay per character via the upto scheme (min $0.002 network settlement floor, so ≤333-char calls settle at $0.002), or flat $0.018 exact.
Turns text into natural speech in English, Spanish, French, Chinese, Japanese or Korean in one or two seconds: Deepgram Aura-2 for English and Spanish, MeloTTS for the rest. Returns a hosted audio URL valid for 24 hours (MP3 for English and Spanish, WAV otherwise) plus its size; add inline=true to also get the base64. Up to 2000 characters per call. You are only charged if the audio is delivered. No API key, no account.
Convert text to speech with the eleven-v4 model, priced per request from the length of the text. It is the most expressive speech tier, and the quote is $0.010 plus $0.115 per 1,000 characters of text, rounded up to the next $0.001 (2,000 characters: $0.240). Inline audio tags such as [whispering] are read as delivery cues. Returns base64-encoded audio. Same interface, voices, formats and backups as /api/tts. No API key needed; pay per call via x402 or MPP. Text capped at 2000 chars.
Convert text to speech with Kokoro-82M, a fraction of the price of /api/tts. Returns base64-encoded mp3 or pcm. The same request shape and the same ten voice names as /api/tts, mapped to Kokoro's own voices; the voice is synthetic-sounding where the /api/tts and /api/tts-hd tiers are not, which is the whole trade. Use this for high-volume narration, notifications and agent speech where the cost per call matters more than the timbre; use /api/tts or /api/tts-hd when it does not.
