Voice Cloning

Create custom voice clones from speech using Octave, either by recording your voice or uploading a sample.

Octave, Hume’s speech-language model, deeply models language and speech patterns to generate voice. While Octave supports voice design from natural language descriptions, it can also create voices from audio samples, reflecting the speaker’s tone, accent, cadence, and vocal identity.

Voice cloning availability depends on your subscription tier. Check your access and usage limits on the billing page.

Create a voice clone

You can create a voice clone using one of two supported methods:

  1. Record your voice using your microphone in a guided session.
  2. Upload an audio file containing a speech sample from a consenting speaker.

To create a voice clone, start from the Platform’s Voice Library page. Click Create voice, then Voice clone to open the voice cloning menu.

The sections below walk through each method step by step.
