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.

PlayHT Voice Cloning API

The API reference is still readable at docs.play.ht, useful for mapping old integrations. Shut down, api.play.ht doesn't resolve.

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

PlayHT Voice Cloning API

  1. Don't call api.play.ht. The host doesn't resolve
  2. Ignore docs.play.ht for new work. It documents an API that no longer exists
  3. Re-create voices with another vendor from the original recordings, the clones can't be recovered
