Georgi Gerganov 83c742f1a7 whisper : add option to speed up the audio tempo by x2 Using a Phase Vocoder for speeding up the audio tempo by scaling down the frequencies in the frequency domain. This reduces the computation in the Encoder by a factor of 2. The transcription accuracy is degraded, but for slow to normal speech - it seems to be still very good. I think this can find application for real-time transcription - i.e. the "stream" example.		2022-11-13 16:25:43 +02:00

main

This is the main example demonstrating most of the functionality of the Whisper model. It can be used as a reference for using the whisper.cpp library in other projects.
