Canary model stuck in a loop? Just repeats the same phrases over and over.
I am facing a similar issue. Any help would be appreciated. Thank you. I am afraid to say this is common with AED models, and this scenario is called hallucination. 

Would it be possible for you to share the audio? @pzelasko FYI This issue is stale because it has been open for 30 days with no activity. Remove stale label or comment or this will be closed in 7 days. Sorry for a late answer. Please try to process that file with this script instead: https://github.com/NVIDIA/NeMo/blob/main/examples/asr/asr_chunked_inference/aed/speech_to_text_aed_chunked_infer.py

it will slice your long segment to shorter chunks and run inference on them. The result should be much better.  This issue is stale because it has been open for 30 days with no activity.

I recorded a 5 minute audio segment on my iPhone 11, at 24 bit / 48Khz, using this as my json input:

{ "audio_filepath": "/ldir/test.wav", "duration": "None", "taskname": "asr", "source_lang": "en", "target_lang": "en", "pnc": "yes", "answer": "na" }

It was just a test recording of me reading from Vol 1 of The Art of Computer Programming. The return from the call to
```
canary_model.transcribe("input_manifest.json", batch_size=16)
```
looks like
```

You can see it starts off OK, but this it just gets stuck in a loop repeating the same word or phrase, and it's much shorter than the audio segment. I have seen this repeatedly in different tests, and I have no idea what's causing it.

I'm using the following to launch the container
```
