## ⚡ Installation (NEW!)

### One-Command Installation
```bash
bash install.sh
```

The installer automatically:
- ✅ Detects your system architecture (ARM64, x86_64)
- ✅ Downloads Piper TTS
- ✅ Downloads 4 Brazilian Portuguese voice models (~240MB)
- ✅ Installs Python dependencies
- ✅ Validates everything works

**No manual downloads. No configuration. Just one command!**

## 🔄 Critical Rules

**DEFAULT: AUDIO ONLY - NO TEXT**

When user sends audio:
- ❌ NO transcription shown
- ❌ NO "Pesquisando...", "Gerando..."
- ❌ NO confirmations or explanations
- ✅ ONLY audio reply

**TEXT MODE:** Say "texto" or "responda em texto" explicitly

## 📊 Workflow

```
🎤 Audio Received (PT-BR/EN)
    ↓
🔤 Transcribe (wav2vec2 PT-BR - silent)
    ↓
🤖 AI Response (Claude API or OpenClaw Agent - silent)
    ↓
🗣️ Synthesize (Piper neural - silent)
    ↓
📤 Send Audio Reply (silent)
```

## 📁 Scripts

### Installation & Setup
- `install.sh` - Automatic installation (run once!)
- `health_check.py` - Validate the installation

### Core Processing
- `transcribe.py` - wav2vec2 PT-BR speech recognition
- `synthesize.py` - Piper TTS with voice selection
- `voice_config.py` - Voice preference management
- `process.sh` - Full workflow orchestration

### AI Integration
- `claude_adapter.py` - Claude API bridge (intelligent responses)

## 🔧 Configuration

### Optional: Enable Claude Integration

For intelligent AI responses, set your API key:
```bash
export ANTHROPIC_API_KEY="sk-your-api-key"
```

Without this, the skill uses OpenClaw's agent (still great responses!).

### Voice Configuration

Current voice is saved automatically in:
```
~/.openclaw/workspace/.audio_pt_voice_config
```
