Verdicts

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.

VoiceStudio

Local audio generation with HTTP and MCP access. Hardware and model licences vary by backend.

Before you call either

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

VoiceStudio

  1. Keep the server on loopback unless network authentication has been verified.
  2. Use file outputs for large audio and restrict the output directory.
  3. Check the selected model licence before commercial voice use.
