Verdicts

Hume Octave Voice Design and Cloning + MCP

Voice design from a natural-language description, saved with one call. Cloning over the API is Enterprise-only.

Soniox Voice Cloning

One API call and a clip of up to 2 minutes. No consent capture or speaker verification, and the terms say so.

Before you call either

Hume Octave Voice Design and Cloning + MCP

  1. Design with POST /v0/tts using an utterance description plus sample text, then save a generation_id with POST /v0/tts/voices
  2. Request several generations and pick one. A saved voice can't be tuned afterwards
  3. List your own voices with GET /v0/tts/voices?provider=CUSTOM_VOICE
  4. Use /v0/tts/file or streaming rather than the JSON endpoint to keep base64 audio out of context
  5. On E0811 back off and retry, the request was rate limited

Soniox Voice Cloning

  1. Poll the voice until the target model's status is ready before using it in TTS
  2. On voice_not_prepared call recompute, don't retry the TTS request
  3. Don't retry voice_failed even though it's a 503. Create a new voice from a better clip
  4. Use a key from the project that owns the voice, voices are per project
  5. Keep the clip under 2 minutes and 35 MB, longer fails with voice_audio_too_long
