Voice Studio is the unified workspace for reusable voices. In the current app, open Voices from the sidebar to manage saved voices, browse built-in voices, and create new cloned or designed voices. The legacy /voice-cloning and /voice-design routes redirect into this workspace when Voice Studio is enabled.

​
What You Can Do

​
Using the Web UI

  1. Open http://localhost:8080.
  2. Select Voices in the sidebar.
  3. Use the Saved, Built-in, or All views to find a voice.
  4. Select New Voice to create a cloned or designed voice.
  5. Select Use in TTS to continue generation in Text to Speech.
The Models action opens the same route-aware model manager used elsewhere in the app. Built-in voice previews require a compatible built-in voice model to be loaded.

​
Saved Voices

Saved voices are reusable voice assets stored by the local server. A saved voice can come from:
  • A reference-audio voice clone
  • A prompt-designed voice
  • A generated voice source saved through the API
Saved voices can be previewed, deleted, and reused in Text to Speech. The API surface is /v1/voices, and izwi tts can reuse a saved voice with --saved-voice-id.

​
Built-In Voices

Built-in voices are model-provided speaker presets. Voice Studio shows the available speakers for the selected model, can generate short preview samples, and can send a speaker into Text to Speech. Use built-in voices when you want quick, repeatable presets without reference audio or a design prompt. Use saved voices when you want a custom reusable voice asset. See Voice Presets for the current speaker IDs.

​
Creating New Voices

Select New Voice from Voice Studio to choose a creation flow: See the dedicated guides for details:

API Routes
