|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Problem: No "TTS warmup complete" log
|
||||
|
||||
**Cause:** TTS synthesizer not calling warmup
|
||||
|
||||
**Fix:**
|
||||
```bash
|
||||
# Check run.py has warmup call
|
||||
grep "warmup" run.py
|
||||
```
|
||||
|
||||
Should see:
|
||||
```python
|
||||
await tts_synthesizer.warmup()
|
||||
```
|
||||
|
||||
**Restart bot after confirming.**
|
||||
|
||||
---
|
||||
|
||||
### Problem: No "Routed to" logs
|
||||
|
||||
**Cause:** Router not integrated into orchestrator
|
||||
|
||||
**Fix:**
|
||||
```bash
|
||||
# Check orchestrator has router
|
||||
grep "query_router" pipeline/orchestrator.py
|
||||
```
|
||||
|
||||
**Verify orchestrator initialization includes router.**
|
||||
|
||||
---
|
||||
|
||||
### Problem: Still slow (>3s latency)
|
||||
|
||||
**Check each stage:**
|
||||
|
||||
1. **STT slow (>1s)?**
|
||||
- Verify `beam_size: 1` in config
|
||||
- Check GPU is being used: `nvidia-smi`
|
||||
|
||||
2. **LLM slow (>2s first sentence)?**
|
||||
- Check OpenClaw Gateway is responding
|
||||
- Verify model routing is working (should use Haiku for simple queries)
|
||||
- Test Gateway directly:
|
||||
```bash
|
||||
curl http://192.168.50.9:18789/health
|
||||
```
|
||||
|
||||
3. **TTS slow (>1s)?**
|
||||
- Check GPU utilization
|
||||
- Verify Chatterbox-Turbo is loaded (not Coqui)
|
||||
- Check cache is enabled in tts.py
|
||||
|
||||
4. **Cache not hitting?**
|
||||
- Check exact LLM responses in logs
|
||||
- Add common variations to `TTSSynthesizer.COMMON_PHRASES`
|
||||
|
||||
---
|
||||
|
||||
### Problem: Router always uses Sonnet
|
||||
|
||||
**Cause:** Queries don't match patterns
|
||||
|
||||
**Debug:**
|
||||
```python
|
||||
# Test router manually
|
||||
from pipeline.query_router import QueryRouter
|
||||
|
||||
router = QueryRouter()
|
||||
print(router.route("Hey Jarvis"))

# Should show: model='haiku', reason='matched_simple_pattern'
|
||||
```
|
||||
|
||||
**Fix:** Add custom patterns to `pipeline/query_router.py`
|
||||

|

|
||||
### Problem: Cache hit rate is 0%
|
||||
|
||||
**Cause:** Phrase normalization mismatch
|
||||
|
||||
**Debug:** Check logs for exact LLM responses. Example:
|
||||
|
||||
```
|
||||
LLM response: "Yes sir." ← Missing comma!
|
||||
Cache key: "yes, sir" ← Has comma
|
||||
```
|
||||
|
||||
**Fix:** Add variation to COMMON_PHRASES or update normalization.

|
||||
| **Simple (uncached)** | 4-7s | 0.7-1.2s | **4-6x faster** ✅ |
|
||||
| **Medium** | 5-9s | 1-2s | **3-5x faster** ✅ |
|
||||
| **Complex** | 6-11s | 1.5-3s | **2-4x faster** ✅ |

|
||||
## Next Steps
|
||||
|
||||
### If Everything Works:
|
||||
|
||||
1. **Test with multiple users** in voice channel
|
||||
2. **Monitor cache hit rate** over time (should increase as common responses are cached)
|
||||
3. **Tune router patterns** for your specific use cases
|
||||
4. **Add more cached phrases** based on actual usage logs
|
||||
|
||||
### If You Want Even Faster (<1s):
|
||||
|
||||
See `OPTIMIZATION_SUMMARY.md` for Phase 2 options:
|
||||
- Kani-TTS-2 evaluation (faster TTS engine)
|
||||
- Full Pipecat integration (500-800ms target)

## Recording Your Results
|
||||
|
||||
Create a results log:
|
||||
|
||||
```bash
|
||||
# Run test session
|
||||
echo "=== Optimization Test Results ===" > test_results.txt
|
||||
echo "Date: $(date)" >> test_results.txt
|
||||
echo "" >> test_results.txt
|
||||
|
||||
# Test each scenario and record
|
||||
echo "Simple Query (cached): Hey Jarvis" >> test_results.txt
|
||||
# ... copy latency from logs
|
||||
|
||||
echo "Simple Query (uncached): Thank you" >> test_results.txt
|
||||
# ... copy latency from logs
|
||||
|
||||
# etc.
|
||||
```
|
||||
|
||||
**Share your results!** Compare before/after latencies to verify the 3-10x improvement.
