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.

Murf Voice Cloning API

One sample of up to 30 seconds, ready in a few minutes. Enterprise only, with no self-serve or trial access.

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

Murf Voice Cloning API

  1. Expect 403 until Murf enables cloning for the workspace
  2. Send a WAV, MP3 or FLAC at 24 kHz or above. A low sample rate is accepted and fails later
  3. Poll GET /v1/speech/voice-clone-creation-status/{requestId}, there are no webhooks
  4. Use clones only with Falcon 2 streaming. Gen2 or the non-streaming endpoint returns 400
