Description

Purpose: generate audio files (OGG/Opus by default) from text, fully offline. No sending is performed by the skill — sending is handled by the agent after the file is ready.

Features

• Self-contained setup via setup() — installs Piper into an isolated venv, no system-wide changes
• Automatic language detection for 20+ languages with English as default
• Per-call voice selection via voice parameter
• On-demand voice download via downloadVoices() — no models bundled, choose what you need
• Voice removal via removeVoice() — clean up voices you no longer want
• Extensible: add any language by installing a Piper .onnx model
