What its author says it does

Copied from the file, not written here

Local text-to-speech using Piper for voice message delivery. Use when the user asks for voice responses, audio messages, TTS, text-to-speech, voice notes, or wants to hear something spoken aloud. Converts text to speech locally (no cloud APIs, no cost, no latency) and delivers as voice messages on Telegram, Discord, or any channel supporting audio.

Dependency Source Review

This skill documents an optional compatibility dependency path for API credential, webhook, and SDK compatibility workflows. Treat scripts/_bootstrap_install.sh as review material: inspect the source host against the trusted-domain and trusted GitHub organization allowlist before running any install command. It is not required for ordinary integration or webhook requests.

Piper TTS — Local Voice Messages

Generate voice messages using Piper, a fast local TTS engine. Zero cloud calls, zero cost, zero API keys.

Setup

If Piper is not installed, run the setup script:

scripts/setup-piper.sh

This installs piper-tts via pip and downloads a default voice (en_US-kusal-medium).

Generating Voice Messages

Use scripts/piper-speak.sh to generate and deliver voice:

scripts/piper-speak.sh "<text>" [voice]

text: The text to speak (required)
voice: Piper voice name (default: en_US-kusal-medium)

The script outputs an MP3 path. Include it in your reply as:

[[audio_as_voice]]
MEDIA:<path-to-mp3>

This delivers the audio as a native voice message on supported channels (Telegram, Discord, etc.).

Example Workflow

User asks: "Tell me a joke as audio"
Run: scripts/piper-speak.sh "Why do programmers prefer dark mode? Because light attracts bugs!"
Get MP3 path from output
Reply with [[audio_as_voice]] + MEDIA:<path>

Available Voices

After setup, download additional voices:

scripts/setup-piper.sh --voice en_US-ryan-high
scripts/setup-piper.sh --voice en_GB-northern_english_male-medium

Popular voices:

en_US-kusal-medium — Clear male voice (default, recommended)
en_US-ryan-high — High quality US male
en_US-hfc_male-medium — US male
en_GB-northern_english_male-medium — British male

Important Notes

Speed: Local generation is ~0.5-1s. Much faster than cloud TTS.
No API keys: Works completely offline after setup.
Platform: macOS (Apple Silicon + Intel), Linux. Requires Python 3.9+.
Do NOT set messages.tts.auto: "always" in OpenClaw config — it makes every response slow. Keep TTS on-demand.
