5 use cases

  • Turn a text file into narration with an AI agent

    An agent reads a script file and saves a narrated WAV using your reference voice, with no desktop app open.

    View prompt
    Using the leemysw/yovoice repo and its Skill at skills/yovoice, read <script.txt> with <reference.wav> as the reference voice in a calm delivery and save the result as <output.wav>. Report the model used and confirm <output.wav> exists and plays back at the expected script length.

  • Dub a script or subtitle file line by line

    Import text or subtitles, assign a voice to each character, and generate every line in the desktop app.

    View prompt
    Using the leemysw/yovoice repo, help me set up a Story dubbing project from <script file> with one voice per character in <character list>. Expected output is one generated audio take per line; verify that every line in the script has a generated take before export.

  • Generate a sung track from your own lyrics offline

    Write a style and lyrics with section markers, then generate a song with ACE-Step 1.5 in the local studio.

    View prompt
    Using the leemysw/yovoice repo, write a Music project with the style <style description> and the lyrics in <lyrics file>, using ACE-Step 1.5. Expected output is a generated song with synced lyrics; verify that all section markers from the lyrics file appear in the playback view.

  • Arrange a multi-part score and export MIDI and stems

    Write parts by bar and beat, import MIDI or let an agent compose, render with a General MIDI sound font, and export.

    View prompt
    Using the leemysw/yovoice repo, create a Score project with the parts described in <arrangement brief> and export the MIDI and stems to <output folder>. Expected output is one MIDI file and one stem per part; verify that each part's bar count matches the brief.

  • Expose local audio generation as an API and MCP server

    Run Yovoice serve so Cursor or Claude Code can call the authenticated HTTP API and MCP inference service.

    View prompt
    Using the leemysw/yovoice repo, run `yovoice serve` on <host machine> and connect Claude Code or Cursor to its MCP endpoint following docs/api.md. Expected output is a short test audio clip returned by the agent; verify that unauthenticated requests are rejected.

How to use Yovoice

  1. Check you have what it needs: macOS 14+ on Apple Silicon, or Windows 10/11 x64 (NVIDIA GPU optional for the CUDA builds); Enough disk space and time to download at least one model inside the app (sizes are listed in docs/models.md); Reference audio of the voice you are allowed to use, if you want cloning.
  2. Open leemysw/yovoice on GitHub and read the README and license.
  3. Give your agent the Yovoice Skill link (https://github.com/leemysw/yovoice/tree/main/skills/yovoice) and ask it to install the Skill and set up the local CLI, engine, and model.
  4. Place narration.txt and a reference voice file voice.wav in the working folder.
  5. Ask the agent to read narration.txt using voice.wav as the reference voice, with a calm delivery, and save it as narration.wav.
  6. Ask the agent to report which model and engine it used, so you can repeat the run. (inferred, check the README)

These steps come from our top use case, Turn a text file into narration with an AI agent, which also has a copy-paste agent prompt.
