   - Created wrapper infer() that delegates to infer_generator()
   - Renamed monolithic method to infer_generator()
   - Changed final returns to yield for generator compatibility
   - Handles both streaming and non-streaming modes

2. Streaming implementation (b0c6ab8) - Added low-latency streaming
   - Added stream_return parameter for generator mode
   - Added more_segment_before parameter for streaming segmentation
   - Integrated with generator-based inference

3. UNK token warnings (34be9bf) - Token validation and user feedback
   - Detects unknown tokens in BPE model
   - Warns users with token IDs and suggestions

4. S2Mel optimization (31e7e85) - Mel-spectrogram generation speedup
   - Optimized fused_add_tanh_sigmoid_multiply() with torch.split
   - Fixed sequence_mask() with max_length parameter
   - Added enable_torch_compile() to CFM and MyModel classes
   - Added use_torch_compile parameter to infer_v2.py

5. GPT2 acceleration (c1ef414) - KV-cache and FlashAttention optimization
   - Created new /accel/ module with 5 files (609-2500 lines)
   - Added use_accel parameter to UnifiedVoice
   - Integrated AccelInferenceEngine for 1.5-3x speedup
   - Optional feature (requires flash-attn library)

Custom modifications preserved:
- QwenEmotion lazy loading with path fallbacks
- W2V-BERT loading from TTS folder (unified downloader integration)
- All custom logging and error handling
- Custom emotion vector processing
