 ### Models Used
 - **Embeddings**: `sentence-transformers/all-MiniLM-L6-v2` - Fast, lightweight semantic search
 - **Name Extraction**: `urchade/gliner_small-v2.1` - Zero-shot NER for person names
-- **Speech-to-Text**: `openai/whisper-tiny` - Optimized for speed on CPU
+- **Speech-to-Text**: `openai/whisper-small` - Better accuracy for multi-language transcription
