I disabled this because there were many complaints about slow decoding. The current implementation does not allow batching the decoders when using the "best of" or "beam size" parameters, so the decoding time is proportional to the number of decoders, which is obviously not great. However, now there are even more complaints about wrong decodings and repetition. So, making a compromise by re-enabling the fallbacks, but defaulting to just 2 "best of" / "beam size" decoders. Also, the temperature step is increased from 0.2 to 0.4 - i.e. from maximum of 5 fallbacks to maximum of 2. Also, the stream example now has fallbacks enabled by default. close #471 #477 #508 #612 #719 #731 |

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.
