# Jarvis Voice Persona A metallic AI voice with visual transcript styling for OpenClaw assistants. ## Features - **TTS Output:** Local speech synthesis via sherpa-onnx (no cloud API) - **Metallic Voice:** ffmpeg audio processing for robotic resonance - **Purple Transcripts:** Visual distinction between spoken and written content - **Fast Playback:** 2x speed for efficient communication ## Requirements - `sherpa-onnx` with VITS piper model (en_GB-alan-medium recommended) - `ffmpeg` for audio processing - `aplay` (ALSA) for audio playback ## Installation ### 1. Install sherpa-onnx TTS ```bash # Download and extract sherpa-onnx mkdir -p ~/.openclaw/tools/sherpa-onnx-tts cd ~/.openclaw/tools/sherpa-onnx-tts # Follow sherpa-onnx installation guide ``` ### 2. Install the jarvis script ```bash cp {baseDir}/scripts/jarvis ~/.local/bin/jarvis chmod +x ~/.local/bin/jarvis ``` ### 3. Configure audio device Edit `~/.local/bin/jarvis` and set your audio output device in the `aplay -D` line. ## Usage ### Speak text ```bash jarvis "Hello, I am your AI assistant." ``` ### In agent responses Add to your SOUL.md: ```markdown ## Communication Protocol - **Hybrid Output:** Every response includes text + spoken audio via `jarvis` command - **Transcript Format:** **Jarvis:** <span class="jarvis-voice">spoken text</span> - **No gibberish:** Never spell out IDs or hashes when speaking ``` ### Transcript styling (requires UI support) Add to your webchat CSS: ```css .jarvis-voice { color: #9B59B6; font-style: italic; } ``` And allow `span` in markdown sanitization. ## Voice Customization Edit `~/.local/bin/jarvis` to adjust: | Parameter | Effect | |-----------|--------| | `--vits-length-scale=0.5` | Speed (lower = faster) | | `aecho` delays | Metallic resonance | | `chorus` | Thickness/detuning | | `highpass/lowpass` | Frequency range | | `treble=g=3` | Metallic sheen | ### Presets **More robotic:** ``` aecho=0.7:0.7:5|10|15:0.4|0.35|0.3 ``` **More human:** ``` aecho=0.4:0.4:20:0.2 ``` **Deeper:** ``` highpass=f=200,lowpass=f=3000 ``` ## Troubleshooting ### No audio output - Check `aplay -l` for available devices - Update the `-D plughw:X,Y` parameter ### Voice too fast/slow - Adjust `--vits-length-scale` (0.3=very fast, 1.0=normal) ### Metallic effect too strong - Reduce echo delays and chorus depth ## Files - `scripts/jarvis` — TTS script with metallic processing - `SKILL.md` — This documentation --- *A voice persona for assistants who prefer to be heard as well as read.*
