|
# Environment variable configuration
|
|
export TTS_BATCH_SIZE=3 # Number of concurrent TTS requests (default: 5)
|
|
```
|
|
|
|
**Recommended Settings by Provider:**
|
|
- **OpenAI TTS**: `TTS_BATCH_SIZE=5` (default, handles high concurrency well)
|
|
- **ElevenLabs**: `TTS_BATCH_SIZE=2` (strict rate limits, reduce for stability)
|
|
- **Google TTS**: `TTS_BATCH_SIZE=4` (moderate concurrency tolerance)
|
|
- **Custom/Local TTS**: `TTS_BATCH_SIZE=1` (depends on hardware/setup)
|
|
|
|
**Performance Trade-offs:**
|
|
- **Higher values (4-5)**: Faster podcast generation, higher provider load
|
|
- **Lower values (1-2)**: Slower generation, more reliable for rate-limited providers
|
|
- **Optimal setting**: Balance between speed and provider stability
|
|
|
|
## 🛠️ Troubleshooting Common Issues
|
|
|
|
### Generation Failures
|
|
#### **Insufficient Content**
|
|
- **Problem**: Episode generation fails with sparse source material
|
|
- **Solution**: Ensure notebook contains substantial research content
|
|
- **Prevention**: Aim for 1000+ words of source material
|
|
|
|
#### **API Quota Limits**
|
|
- **Problem**: TTS or LLM API limits exceeded
|
|
- **Solution**: Check API quotas and upgrade plans if needed
|
|
- **Prevention**: Monitor usage and set up billing alerts
|
|
|
|
#### **TTS Concurrency Issues**
|
|
- **Problem**: TTS provider rate limiting or concurrent request failures
|
|
- **Solution**: Configure TTS batch size to reduce parallel audio generation
|
|
- **Environment Variable**: `TTS_BATCH_SIZE=2` (default: 5)
|
|
- **Usage**: Lower values reduce provider load but increase generation time
|
|
```bash
|
|
# Reduce concurrent TTS requests for providers with strict limits
|
|
export TTS_BATCH_SIZE=2
|
|
# or
|
|
export TTS_BATCH_SIZE=1 # Most conservative, slowest
|
|
```
|
|
|
|
#### **Voice Configuration Errors**
|
|
- **Problem**: Specific voice not available or misconfigured
|
|
- **Solution**: Verify TTS provider settings and voice availability
|
|
- **Prevention**: Test voice configurations before full generation
|
|
|
|
### Audio Quality Issues
|
|
#### **Poor Audio Quality**
|
|

|
|
|
|
#### **Inconsistent Volume**
|
|
- **Problem**: Speakers at different volume levels
|
|

|
|
- **Prevention**: Use consistent TTS provider for all speakers
|
|
|
|
#### **Unnatural Speech**
|
|
- **Problem**: Robotic or awkward speech patterns
|
|
- **Solution**: Adjust personality settings and try different TTS providers
|
|
- **Prevention**: Test speaker configurations with sample content
|
|
|
|
### Performance Issues
|
|
#### **Slow Generation**
|
|
- **Problem**: Podcast generation takes excessive time
|
|
- **Solution**: Check API response times and consider provider switching
|
|
- **Prevention**: Monitor system resources and API performance
|
|
|
|
#### **Memory Issues**
|
|
- **Problem**: High memory usage during generation
|
|
- **Solution**: Reduce concurrent podcast generations
|
|
- **Prevention**: Monitor system resources and optimize content size
|
|
|
|
### Content Issues
|
|
#### **Repetitive Content**
|
|
- **Problem**: Speakers repeating same information
|
|
- **Solution**: Improve source material diversity and speaker role definitions
|
|
- **Prevention**: Ensure varied source content and clear speaker differentiation
|
|
|
|
#### **Off-Topic Discussions**
|
|
- **Problem**: Podcast content straying from research material
