Passing --diarize result always in (speaker ?)

[MichelBahl]

No matter what stereo mp3 I convert with ffmpeg to wave --diarize did not work.

Does anyone have a working sample mp3/wave file?

I used following command:
./main -di -m models/ggml-medium.bin -f ./myfile.wav

The results look always like:

[00:00:00.000 --> 00:00:03.500] (speaker ?) Say hello to Picnic, the supermarket that comes to your house.
[00:00:03.500 --> 00:00:07.100] (speaker ?) Huge selection, super fresh and always delivered for free.
[00:00:07.100 --> 00:00:09.300] (speaker ?) Try our family recipes as well.
[00:00:09.300 --> 00:00:10.800] (speaker ?) One click and everything is there.
[00:00:10.800 --> 00:00:12.700] (speaker ?) Download the Picnic app now.
[00:00:12.700 --> 00:00:15.000] (speaker ?) The number one for families in Berlin.
[00:00:15.000 --> 00:00:22.700] (speaker ?) 6 Minute English from bbclearningenglish.com
[00:00:22.700 --> 00:00:26.200] (speaker ?) Hello. This is 6 Minute English from BBC Learning English.
[00:00:26.200 --> 00:00:27.000] (speaker ?) I'm Phil.
[00:00:27.000 --> 00:00:28.300] (speaker ?) And I'm Georgie.
[00:00:28.300 --> 00:00:31.800] (speaker ?) We all know how important exercise is to stay fit
[00:00:31.800 --> 00:00:34.200] (speaker ?) and reduce the risk of heart disease.
[00:00:34.200 --> 00:00:36.200] (speaker ?) Do you exercise much, Phil?
[00:00:36.200 --> 00:00:39.300] (speaker ?) I try to. I ride my bike at the weekend.
[00:00:39.300 --> 00:00:43.300] (speaker ?) But to be honest, I do spend a lot of time sitting down.

--diarize is very basic and works only with stereo audio where each speaker is in a separate channel
