// how it works

How it works

  1. Pick the job

    Transcription, synthesis, voice changing, or editing — each tool here majors in one.

  2. Install and set up

    Binaries, pip packages, or Docker; models download on first run for AI tools.

  3. Feed it audio or text

    Drop in a recording or type what you want spoken.

  4. Export the result

    WAV/MP3/OGG outputs drop straight into editors or apps.

Free for products

Open licenses let you ship voice features without per-minute API bills.

Scriptable

CLI and Python APIs slot into larger pipelines.

Multilingual

Dozens of languages supported, not just English.
