## Performance Monitoring
|
|
|
|
### Real-Time Metrics
|
|
|
|
The Enhanced CLI displays live performance metrics during processing:
|
|
|
|
```bash
|
|
CPU: 45.2% | Memory: 2.1GB/8GB (26%) | Temp: 65°C
|
|
```
|
|
|
|
**Metrics Explained:**
|
|
- **CPU**: Current CPU utilization percentage
|
|
- **Memory**: Used memory / Total memory (percentage)
|
|
- **Temperature**: CPU temperature in Celsius (when available)
|
|
|
|
### Performance Guidelines
|
|
|
|
#### System Recommendations
|
|
- **Conservative**: 2-4 concurrent workers, small model
|
|
- **Balanced**: 4-6 concurrent workers, base model
|
|
- **Aggressive**: 6-8 concurrent workers, large model
|
|
|
|
#### Memory Usage
|
|
- **Small Model**: ~1GB per process
|
|
- **Base Model**: ~1.5GB per process
|
|
- **Large Model**: ~2GB per process
|
|
|
|
#### Processing Speed
|
|
- **v1 Pipeline**: <30 seconds for 5-minute audio
|
|
- **Real-time Factor**: <0.1 (much faster than real-time)
|
|
|
|
## Error Handling
|
|
|
|
### Error Categories
|
|
|
|
#### File Errors
|
|
```bash
|
|
❌ File not found: lecture.mp3
|
|
💡 Check that the input file path is correct and the file exists.
|
|
```
|
|
|
|
#### Memory Errors
|
|
```bash
|
|
❌ Memory error. Try using a smaller model with --model small or reduce concurrency.
|
|
```
|
|
|
|
#### GPU Errors
|
|
```bash
|
|
❌ CUDA out of memory
|
|
💡 GPU-related error. Try using --device cpu instead.
|
|
```
|
|
|
|
#### Permission Errors
|
|
```bash
|
|
❌ Permission denied: protected.wav
|
|
💡 Check file permissions or run with administrator privileges.
|
|
```
|
|
|
|
#### Generic Errors
|
|
```bash
|
|
❌ Invalid parameter
|
|
💡 Check input parameters and try again.
|
|
```
|
|
|
|
### Error Recovery
|
|
|
|
The Enhanced CLI provides specific guidance for each error type:
|
|
|
|
1. **File Issues**: Path validation and existence checks
|
|
2. **Memory Issues**: Model size and concurrency suggestions
|
|
3. **GPU Issues**: Device fallback recommendations

## Advanced Features
|
|
|
|
### Speaker Diarization
|
|
|
|
Identify and separate different speakers in audio:
|
|
|
|
```bash
|
|
# Enable diarization with 2 speakers
|
|
uv run python -m src.cli.enhanced_cli transcribe interview.mp4 --diarize --speakers 2
|
|
|
|
# Batch processing with diarization
|
|
uv run python -m src.cli.enhanced_cli batch ~/Interviews --diarize --speakers 3
|
|
```
|
|
|
|
**Requirements:**
|
|
- pyannote.audio library installed
|
|
- HuggingFace token for speaker diarization models
|
|
|
|
### Domain Adaptation
|
|
|
|
Optimize transcription for specific content types:
|
|
|
|
```bash
|
|
# Medical content
|
|
uv run python -m src.cli.enhanced_cli transcribe medical_audio.wav --domain medical
|
|
|
|
# Academic lectures
|
|
uv run python -m src.cli.enhanced_cli transcribe lecture.mp3 --domain academic
|
|
|
|
# Technical content
|
|
uv run python -m src.cli.enhanced_cli transcribe tech_podcast.mp3 --domain technical
|
|
```
|
|
|
|
**Available Domains:**
|
|
- `general` - General purpose (default)
|
|
- `technical` - Technical and scientific content
|
|
- `medical` - Medical and healthcare content
|
|
- `academic` - Academic and educational content
|
|
|
|
## Common Workflows
|
|
|
|

|
|
uv run python -m src.cli.main batch-urls research_videos.txt
|
|
|
|
# 2. Download selected videos
|
|
uv run python -m src.cli.main youtube https://youtube.com/watch?v=interesting --download
|
|
|

|
-f vtt \
|
|
--diarize \
|
|
--speakers 3 \
|
|
-c 2
|
|
```
|
|
|
|
## Integration with Taskmaster
|
|
|
|
Track CLI operations using Taskmaster:
|
|
|
|
```bash
|
|
# Create task for batch processing
|
|
./scripts/tm_master.sh add "Process podcast archive with enhanced CLI"
|
|
|
|
# Track progress
|
|
./scripts/tm_workflow.sh update 15 "Processed 50 files, 10 remaining"
|
|
|
|
# Mark complete
|
|
./scripts/tm_master.sh done 15
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Common Issues
|
|
|
|
#### Import Errors
|
|
```bash
|
|
ModuleNotFoundError: No module named 'pyannote'
|
|
```
|
|
**Solution**: Install optional dependencies for diarization
|
|
```bash
|
|
uv pip install pyannote.audio
|
|
```
|
|
|
|
#### Memory Issues
|
|
```bash
|
|
Memory error. Try using a smaller model with --model small or reduce concurrency.
|
|
```
|
|
**Solution**: Use smaller model or reduce concurrency
|
|
```bash
|
|
uv run python -m src.cli.enhanced_cli transcribe file.wav -m small -c 1
|
|
```
|
|
|
|
#### GPU Issues
|
|
```bash
|
|
CUDA out of memory
|
|
```
|
|
**Solution**: Switch to CPU processing
|
|
```bash
|
|
uv run python -m src.cli.enhanced_cli transcribe file.wav -d cpu
|
|
```
|
|
|
|
### Performance Optimization
|
|
|
|
#### For Memory-Constrained Systems
|
|
- Use `-m small` or `-m tiny` models
|
|
- Reduce concurrency with `-c 1` or `-c 2`
|
|
- Process smaller files first
|
|
|
|
#### For High-Performance Systems
|
|
- Use `-m large` models for best accuracy
|
|
- Increase concurrency with `-c 8` or higher
|
|
- Enable GPU processing with `-d cuda`
|
|
|
|
#### For Batch Processing
|
|
- Start with conservative settings
|
|
- Monitor system resources
|
|
- Adjust concurrency based on performance
|
|
|
|
## Development
|
|
|
|
### Architecture
