Yes. In situations where the model exhibits hallucinations with high confidence (avg_log_probs), this
Which branch are you using? I can't find the hallucinations you mentioned.

I was using this PR @ 476dff4, unless I did something wrong, but this was on a Mac using the Metal gpu backend so that could make a difference. I'll retest on CPU and CUDA shortly and let you know. |
Hi! @bobqianic new version is very robust! On my test files, main branch emit 10 hallucinations on 26 WAV files (model But Also it give the error on specific file: What can we do for fix it, how do you think?

Thank you! |
Hello @ukolovda I took a look at this yesterday evening. Whats missing in server.cpp is what you mentioned:
I got an output in the terminal by circumventing the print_realtime flag(instead of using a callback segment). So the model does in fact generate the output string but for some unknown reason |
Hello, @felrock ! Thank you! |

What's the status of this PR? is it safe to use? |
I'm thinking about including this pull request in the R wrapper at audio.whisper . There the current approach to handle some of the hallucinations is to use R packages audio.vadwebrtc or audio.vadsilero to detect silences or general non-voiced signals and either
I haven't looked into the extreme details on this pull request (only skimmed through the logic which was changed in main.cpp and whisper.cpp) but would it make sense already to incorporate this pull request in audio.whisper or are there a lot of changes to be expected here or is this pull request going to be split into a BPE change (#1854) and a change regarding how to handle non-speech? |
@bobqianic are you pursuing this at the moment? |
No, at least not in May. I'm really tied up with a lot of things this month. |
The best way to include Silero Voice Activity into whisper.cpp is to add thirdparty package of onnxruntime1.12.1 dll, then call silero onnx model. My branch had added it. Even VAD, the hallucinations on silent intervals is also happenning. |
I recommend considering a previous Silero VAD version, namely v3.1. The current version v4 (at the moment of writing) often hallucinates speech on lengthy chunks of silent or near-silent audio segments. But you have to add a heavyweight dependency like onnxruntime just to run a 750KB model. The smallest size I could possibly reduce onnxruntime.dll to was about 2.2MB, which is still 3x the size of silero weights, and requires a lengthy custom build of onnxruntime from source with reduced operator set configs and other size reduction options. And prebuilt redistributables are easily 5-9 MB or more. I have a working Silero v3.1 implementation in pure C, but as much as I would like to suggest it as an option, the code is quite bad, I wrote it as a personal project for learning low level neural nets. |
@bobqianic, Could you rebase your changes? I'd like to test those improvements of yours with production data on our setup. |
Fix compatibility issue
@ziegenberg I did some testing, and it LGTM. If the CI is mostly green, you can proceed with your testing now. |
I already did some testing and fixed some of the errors on my own. Looks promising. I see less hallucinations, but I need to do some more statistics. I will switch to your branch for the next tests. Is your PR #1854 also related to this improvement? |
What data/statistics would you need from my side to consider this PR validated and get it merged? |
Thank you. If you have the ground truth text, please calculate the WER. |

I tested three videos and I had this problem. The common feature of these videos is that there is a music section that begins to mess up the timeline. |
