Edge TTS Unlimited

Free, unlimited neural TTS. No API key. No credits. No character limits.

Use this skill for

  • long-form audio generation
  • spoken briefs and voice notes
  • server-side or headless TTS on Fly.io, VPS, or Docker
  • cases where paid TTS quotas are unnecessary

Prefer this skill over premium TTS when cost and length matter more than voice cloning or premium voice acting.

Quick start

Generate from text:

bash
scripts/speak.sh "Hello world" -o output.mp3

Generate from file:

bash
scripts/speak.sh --file /tmp/my-script.txt -o output.mp3

With voice and speed:

bash
scripts/speak.sh --file script.txt -v en-US-GuyNeural -r "+5%" -o brief.mp3

Requirements

  • Python 3.8+
  • uv preferred, or pip

The script auto-detects uv, falls back to pip, and runs edge-tts without requiring a dedicated venv.

Voice presets

  • news-us → en-US-GuyNeural +5%
  • news-bbc → en-GB-RyanNeural
  • calm → en-US-AndrewNeural -10%
  • fast → en-US-ChristopherNeural +20%

Example:

bash
scripts/speak.sh --file brief.txt --preset news-us -o brief.mp3

Options

bash
scripts/speak.sh [TEXT] [OPTIONS]
  TEXT              Text to speak (or use --file)
  --file, -f FILE   Read text from file
  --voice, -v NAME  Voice name (default: en-US-GuyNeural)
  --rate, -r RATE   Speed adjustment like "+5%" or "-10%"
  --preset, -p NAME Use a preset voice profile
  --output, -o FILE Output path (default: /tmp/tts-{timestamp}.mp3)
  --list            List available voices
  --list-filter STR Filter voice list

Useful voices

  • en-US-GuyNeural — strong default for briefs
  • en-US-ChristopherNeural — authoritative US male
  • en-US-AriaNeural — confident US female
  • en-GB-RyanNeural — steady British male
  • en-GB-SoniaNeural — British female

List voices:

bash
scripts/speak.sh --list
scripts/speak.sh --list-filter british
scripts/speak.sh --list-filter female

Notes

  • Use --file for anything longer than a short sentence.
  • +5% sounds natural for news and summaries.
  • Output is compact MP3 suitable for voice content.
  • This is not for real-time streaming, voice cloning, or premium character acting.
