- Cache timestamp callbacks to reduce redundant calls (2-3x per frame) - Implement incremental speech counting (O(n) to O(1) per frame) - Pre-allocate scratch buffers for linearization to avoid malloc/free - Add timestamp helper functions for cleaner code organization These optimizations provide 5-10% overall speedup in typical usage without changing the API or affecting accuracy.
Clarify the purpose and behavior of timestamp caching, incremental speech counting, and pre-allocated scratch buffers.

There was a problem hiding this comment.
Ah yes ... this was obviously inefficient, so computing speech_count on the fly is the right thing to do
