What its author says it does

Copied from the file, not written here

Free, unlimited text-to-speech using Microsoft Edge neural voices via Python edge-tts. Use when generating long-form audio, podcasts, voice notes, spoken briefs, or headless/server-side TTS without API keys, credits, or character limits.

SKILL.md

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:

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

Generate from file:

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

With voice and speed:

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:

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

Options

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:

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.
