# OpenClaw Voice Bot - Usage Guide
|
||||
|
||||
## What is This?
|
||||
|
||||
**OpenClaw Voice Bot** is a complete, production-ready voice assistant implementation for Discord that enables AI agents to naturally participate in voice conversations. It's designed to integrate with any LLM backend (OpenClaw, OpenAI, Anthropic, etc.) and provides:
|
||||
|
||||
- **Passive Voice Listening** - No wake words or push-to-talk required
|
||||
- **Smart Turn Detection** - Uses Pipecat Smart Turn v3 to detect natural conversation completion
|
||||
- **Intelligent Response Filtering** - Two-tier relevance system (fast keyword + slow LLM) prevents over-responding
|
||||
- **GPU-Accelerated STT/TTS** - faster-whisper and Chatterbox TTS for low-latency processing
|
||||
- **Multi-Agent Support** - Switch between different AI personalities (Jarvis, Sage, etc.)
|
||||
- **OpenAI-Compatible API** - HTTP endpoints for TTS/STT that work with any client
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
```
|
||||
Discord Voice Channel
|
||||

|
||||
↓
|
||||
Silero VAD (speech segmentation)
|
||||
↓
|
||||
Pipecat Smart Turn v3 (turn completion detection)

|
||||
↓
|
||||
YOUR LLM BACKEND (OpenClaw / OpenAI / Anthropic / etc.)
|
||||
↓
|
||||
Chatterbox TTS (GPU-accelerated, paralinguistic)
|
||||
↓
|
||||
Discord Voice TX (48kHz stereo playback)
|
||||
```
|
||||
|
||||
**Plus:** FastAPI server with OpenAI-compatible `/v1/audio/speech` and `/v1/audio/transcriptions` endpoints.
|
||||
|
||||
## System Requirements
|
||||
|
||||
### Hardware
|
||||
- **GPU:** NVIDIA GPU with CUDA support (RTX 3060+ recommended, 8GB+ VRAM)
|
||||
- **RAM:** 16GB minimum, 32GB+ recommended
|
||||
- **Storage:** 10GB free space (for models and voice files)
|
||||
|
||||
### Software
|
||||
- **OS:** Windows 10/11, Linux
|
||||
- **Python:** 3.12 or higher
|
||||
- **CUDA:** 12.x (for GPU acceleration)

|
||||
|
||||
## Installation
|
||||
|
||||
### 1. Clone Repository
|
||||
|
||||
```bash
|
||||
git clone https://github.com/MCKRUZ/openclaw-voice.git
|
||||
cd openclaw-voice
|
||||
```
|
||||
|
||||
### 2. Install Dependencies
|
||||
|
||||
**Windows:**
|
||||
```batch
|
||||
setup.bat
|
||||
```
|
||||
|
||||
**Linux:**
|
||||
```bash
|
||||
chmod +x setup.sh
|
||||
./setup.sh
|
||||
```
|
||||
|
||||
This will:
|
||||
- Create Python virtual environment
|
||||
- Install all dependencies
|
||||
- Download ML models (on first run)
|
||||
- Set up directory structure
|
||||
|
||||
### 3. Configure Environment
|
||||
|
||||
**Create `.env` file:**
|
||||
```bash
|
||||
cp .env.example .env
|
||||
```
|
||||
|
||||
**Edit `.env` with your configuration:**
|
||||
|
||||
```bash
|
||||
# Discord
|
||||
DISCORD_BOT_TOKEN=your_discord_bot_token_here
|
||||
|
||||
# Your LLM Backend (choose one or configure custom)
|
||||
# Option 1: OpenClaw Gateway (if you have OpenClaw running)
|
||||
OPENCLAW_BASE_URL=http://localhost:18789
|
||||
OPENCLAW_AUTH_TOKEN=your_gateway_token
|
||||
|
||||
# Option 2: OpenAI Direct
|
||||
OPENAI_API_KEY=sk-...
|
||||
|
||||
# Option 3: Anthropic Direct
|
||||
ANTHROPIC_API_KEY=sk-ant-...
|
||||
|
||||
# Server
|
||||
SERVER_HOST=0.0.0.0
|
||||
SERVER_PORT=8880
|
||||
|
||||
# Pipeline (optional overrides)
|
||||
# PIPELINE__STT__MODEL_SIZE=medium
|
||||
# PIPELINE__STT__DEVICE=cuda
|
||||
# PIPELINE__TTS__DEVICE=cuda
|
||||
```
|
||||
|
||||
### 4. Provide Voice Reference Files
|
||||
|
||||
Place 10-30 second voice samples in `server/voices/`:
|
||||
- `server/voices/jarvis.wav` - Voice reference for Jarvis agent
|
||||
- `server/voices/sage.wav` - Voice reference for Sage agent
|
||||
|
||||
**Requirements:**
|
||||
- Format: WAV
|
||||
- Sample rate: 22-48kHz
|
||||
- Duration: 10-30 seconds
|
||||
- Quality: Clean speech, minimal background noise
|
||||
|
||||
**Validate voice files:**
|
||||
```bash
|
||||
python scripts/validate_voices.py
|
||||
```
|
||||
|
||||
### 5. Discord Bot Setup
|
||||
|
||||
1. Go to [Discord Developer Portal](https://discord.com/developers/applications)
|
||||
2. Create a new application
|
||||
3. Go to "Bot" section → Click "Add Bot"
|
||||
4. Enable these Privileged Gateway Intents:
|
||||
- Server Members Intent
|
||||
- Message Content Intent
|
||||
5. Copy bot token to `.env` file
|
||||
6. Go to "OAuth2" → "URL Generator"
|
||||
7. Select scopes: `bot`, `applications.commands`
|
||||
8. Select permissions:
|
||||
- Send Messages
|
||||
- Connect (Voice)
|
||||
- Speak (Voice)
|
||||
- Use Voice Activity
|
||||
9. Use generated URL to invite bot to your server
|
||||
|
||||
## Integrating Your LLM Backend
|
||||
|
||||
The bot uses a clean interface in `openclaw_client/client.py` that you need to implement for your LLM backend.
|
||||
|
||||
### Current Implementation (Stub)
|
||||
|
||||
The repository includes a **stub implementation** that you replace with your actual LLM integration:
|
||||
|
||||
```python
|
||||
# openclaw_client/client.py
|
||||
|
||||
async def _send_request(self, agent: str, message: str, context: str, speaker: str) -> str:
|
||||
"""
|
||||
TODO: Replace with actual LLM API when available.
|
||||
|
||||
This is where you integrate YOUR LLM backend:
|
||||
- OpenClaw Gateway (OpenAI-compatible endpoint)
|
||||
- OpenAI API (direct)
|
||||
- Anthropic API (direct)
|
||||
- Local LLM (llama.cpp, vLLM, etc.)
|
||||
- Custom API
|
||||
"""
|
||||
# Your implementation here
|
||||
```
|
||||
|
||||
### Integration Options
|
||||
|
||||
#### Option 1: OpenClaw Gateway
|
||||
|
||||
If you run OpenClaw, use its OpenAI-compatible chat completion endpoint:
|
||||
|
||||
```python
|
||||
import httpx
|
||||
|
||||
async def _send_request(self, agent, message, context, speaker):
|
||||
url = f"{self.config.base_url}/v1/chat/completions"
|
||||
headers = {"Authorization": f"Bearer {self.config.auth_token}"}
|
||||
|
||||
messages = [
|
||||
{"role": "system", "content": self.AGENT_PERSONALITIES[agent]},
|
||||
{"role": "system", "content": f"Recent conversation:\n{context}"},
|
||||
{"role": "user", "content": f"[Voice] {speaker} said: {message}"}
|
||||
]
|
||||
|
||||
async with httpx.AsyncClient() as client:
|
||||
response = await client.post(url, json={
|
||||
"model": agent,
|
||||
"messages": messages,
|
||||
"stream": False
|
||||
}, headers=headers)
|
||||
data = response.json()
|
||||
return data["choices"][0]["message"]["content"]
|
||||
```
|
||||
|
||||
#### Option 2: OpenAI Direct
|
||||
|
||||
```python
|
||||
from openai import AsyncOpenAI
|
||||
|
||||
async def _send_request(self, agent, message, context, speaker):
|
||||
client = AsyncOpenAI(api_key=os.getenv("OPENAI_API_KEY"))
|
||||
|
||||
response = await client.chat.completions.create(
|
||||
model="gpt-4",
|
||||
messages=[
|
||||
{"role": "system", "content": self.AGENT_PERSONALITIES[agent]},
|
||||
{"role": "system", "content": f"Recent conversation:\n{context}"},
|
||||
{"role": "user", "content": f"[Voice] {speaker} said: {message}"}
|
||||
]
|
||||
)
|
||||
return response.choices[0].message.content
|
||||
```
|
||||
|
||||
#### Option 3: Anthropic Direct
|
||||
|
||||
```python
|
||||
from anthropic import AsyncAnthropic
|
||||
|
||||
async def _send_request(self, agent, message, context, speaker):
|
||||
client = AsyncAnthropic(api_key=os.getenv("ANTHROPIC_API_KEY"))
|
||||
|
||||
system_prompt = f"{self.AGENT_PERSONALITIES[agent]}\n\nRecent conversation:\n{context}"
|
||||
|
||||
response = await client.messages.create(
|
||||
model="claude-3-5-sonnet-20241022",
|
||||
max_tokens=1024,
|
||||
system=system_prompt,
|
||||
messages=[
|
||||
{"role": "user", "content": f"[Voice] {speaker} said: {message}"}
|
||||
]
|
||||
)
|
||||
return response.content[0].text
|
||||
```
|
||||
|
||||

### Before Going Live
|
||||
|
||||
- [ ] Download real Smart Turn v3 model from HuggingFace `pipecat-ai/smart-turn-v3`
|
||||
- [ ] Remove mock ONNX model (`scripts/create_mock_turn_model.py`)
|
||||
- [ ] Configure actual LLM backend (replace stub in `openclaw_client/client.py`)
|
||||
- [ ] Provide high-quality voice reference files
|
||||
- [ ] Test end-to-end voice flow
|
||||
- [ ] Run full test suite: `pytest`
|
||||
- [ ] Monitor GPU memory and CPU usage
|
||||
- [ ] Test with multiple concurrent users
|
||||
- [ ] Set up logging/monitoring
|
||||
- [ ] Configure rate limiting (if exposing API publicly)
|
||||
- [ ] Review security settings (CORS, auth)
|
||||
|
||||
### Performance Targets

|
||||
| Relevance (fast) | 10ms | 20ms |
|
||||
| Relevance (slow) | 1000ms | 2000ms |
|
||||
| LLM Backend | 2000ms | 5000ms |
|
||||

||||
| faster-whisper (large-v3) | ~4GB |
|
||||
| Chatterbox TTS | ~2-3GB |
|
||||
| Smart Turn v3 (CPU) | 0GB |
|
||||
| Silero VAD (CPU) | 0GB |
|
||||
| **Total** | **~4-7GB** |
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
See [README.md](README.md#troubleshooting) for detailed troubleshooting guide.
|
||||
|
||||
Common issues:
|
||||
- **Bot doesn't join voice channel** → Check Discord permissions
|
||||
- **No audio output** → Validate voice reference files
|
||||
- **Bot responds to everything** → Lower sensitivity: `/sensitivity low`
|
||||
- **GPU out of memory** → Use smaller STT model: `PIPELINE__STT__MODEL_SIZE=small`
|
||||
- **High latency** → Check LLM backend response time
|
||||
|
||||
## Testing
|
||||
|
||||
```bash
|
||||
# Run all tests (318 tests)
|
||||
pytest
|
||||
|
||||
# With coverage
|
||||
pytest --cov=. --cov-report=html
