Local offline TTS → Telegram Voice Note

Convert any text to a Telegram voice message using piper TTS — fully offline, no cloud API required. Runs on Linux (including Raspberry Pi / ARM64).

When to use

• Send spoken responses instead of text messages
• Read out summaries, alerts, or reports
• Any task where audio feedback is more natural than text

Usage

python3 say.py "Your agent is ready."
python3 say.py "Good morning!" --chat-id 123456789
echo "Task complete." | python3 say.py

Configuration

Set these environment variables (or add to ~/.openclaw/.env):

Variable	Required	Description
TELEGRAM_BOT_TOKEN	Yes	Your Telegram bot token
TELEGRAM_CHAT_ID	Optional	Default chat ID (can be passed as --chat-id)

Environment Variables

TELEGRAM_BOT_TOKEN=required   # Telegram bot token — get one from @BotFather
TELEGRAM_CHAT_ID=optional     # Default target chat ID
