- Fix state detection priority: dictation now takes precedence over conversation - Fix critical bug: event loop was created but never started, preventing async coroutines from executing - Optimize audio processing: reorder AcceptWaveform/PartialResult checks - Switch to faster Vosk model: vosk-model-en-us-0.22-lgraph for 2-3x speed improvement - Reduce block size from 8000 to 4000 for lower latency - Add filtering to remove spurious 'the', 'a', 'an' words from start/end of transcriptions - Update toggle-dictation.sh to properly clean up conversation lock file - Improve batch audio processing for better responsiveness

# AI Dictation Service - Test Results and Fixes
|
|
|
|
## 🧪 **Test Results Summary**
|
|
|
|
### ✅ **What's Working Perfectly:**
|
|
|
|
#### **VLLM Integration (FIXED!)**
|
|
- ✅ **VLLM Service**: Running on port 8000
|
|
- ✅ **Model Available**: `Qwen/Qwen2.5-7B-Instruct-GPTQ-Int4`
|
|
- ✅ **API Connectivity**: Working with correct model name
|
|
- ✅ **Test Response**: "Hello! I'm Qwen from Alibaba Cloud, and I'm here and working!"
|
|
- ✅ **Authentication**: API key `vllm-api-key` working correctly
|
|
|
|
#### **System Components**
|
|
- ✅ **Audio System**: `arecord` and `aplay` available and tested
|
|
- ✅ **System Notifications**: `notify-send` working perfectly
|
|
- ✅ **Key Scripts**: All executable and present
|
|
- ✅ **Lock Files**: Creation/removal working
|
|
- ✅ **State Management**: Mode transitions tested
|
|
- ✅ **Text Processing**: Filtering and formatting logic working
|
|
|
|
#### **Available VLLM Models (from `vllm list`):**
|
|
- ✅ `tinyllama-1.1b` - Fast, basic (VRAM: 2.5GB)
|
|
- ✅ `qwen-1.8b` - Good reasoning (VRAM: 4.0GB)
|
|
- ✅ `phi-3-mini` - Excellent reasoning (VRAM: 7.5GB)
|
|
- ✅ `qwen-7b-quant` - ⭐⭐⭐⭐ Outstanding (VRAM: 4.8GB) **← CURRENTLY LOADED**
|
|
|
|
### 🔧 **Issues Identified and Fixed:**
|
|
|
|
#### **1. VLLM Model Name (FIXED)**
|
|
**Problem**: Tests were using model name `"default"` which doesn't exist
|
|
**Solution**: Updated to use correct model name `"Qwen/Qwen2.5-7B-Instruct-GPTQ-Int4"`
|
|
**Files Updated**:
|
|
- `src/dictation_service/ai_dictation_simple.py`
|
|
- `src/dictation_service/ai_dictation.py`
|
|
|
|
#### **2. Missing Dependencies (FIXED)**
|
|
**Problem**: Tests showed missing `sounddevice` module
|
|
**Solution**: Dependencies installed with `uv sync`
|
|
**Status**: ✅ Resolved
|
|
|
|
#### **3. Service Configuration (PARTIALLY FIXED)**
|
|
**Problem**: Service was running old `enhanced_dictation.py` instead of AI version
|
|
**Solution**: Updated service file to use `ai_dictation_simple.py`
|
|
**Status**: 🔄 In progress - needs sudo for final fix
|
|
|
|
#### **4. Test Import Issues (FIXED)**
|
|
**Problem**: Missing `subprocess` import in test file
|
|
**Solution**: Added `import subprocess` to `test_original_dictation.py`
|
|
**Status**: ✅ Resolved
|
|
|
|
## 🚀 **How to Apply Final Fixes**
|
|
|
|
### **Step 1: Fix Service Permissions (Requires Sudo)**
|
|
```bash
|
|
./fix_service.sh
|
|
```
|
|
|
|
Or run manually:
|
|
```bash
|
|
sudo cp dictation.service /etc/systemd/user/dictation.service
|
|
systemctl --user daemon-reload
|
|
systemctl --user start dictation.service
|
|
```
|
|
|
|
### **Step 2: Verify AI Conversation Mode**
|
|
```bash
|
|
# Create conversation lock file to test
|
|
touch conversation.lock
|
|
|
|
# Check service logs
|
|
journalctl --user -u dictation.service -f
|
|
|
|
# Test with voice (Ctrl+Alt+D when service is running)
|
|
```
|
|
|
|
### **Step 3: Test Complete System**
|
|
```bash
|
|
# Run comprehensive tests
|
|
./run_all_tests.sh
|
|
|
|
# Test VLLM specifically
|
|
python test_vllm_integration.py
|
|
|
|
# Test individual conversation flow
|
|
python -c "
|
|
import asyncio
|
|
from src.dictation_service.ai_dictation_simple import ConversationManager
|
|
async def test():
|
|
cm = ConversationManager()
|
|
await cm.process_user_input('Hello AI, how are you?')
