Error in onnxruntime while aligning speech to transcript using whisper

[cvl01]

I am getting the following error when using the whisper engine with align.

Command I am running, for reference: echogarden align "audio.wav" "transcript.txt" "result.srt" "result.json" --language=nl --crop=false --engine=whisper

Never seen it before. Could be a lot of things, including an ONNX runtime issue. Can you send the audio and transcript that produces it?

[cvl01]

No, unfortunately I cannot share the audio, it is confidential.

I am getting this error on about 10 out of 20 audio files that I processed.

[rotemdan]

The error looks like it has to do with some issue with an input tensor or its dimensions.

• Are you using cpu provider (there can be all sorts of errors with DirectML or CUDA)?
• What OS are you using? I've tested it on Windows mostly.
• Do you know which exact line produces this error? That would help a lot. I could narrow it down to things like which of the two models (encoder / decoder) it happens, and when exactly when.
• Does it happens with other sizes of Whisper models like base or small?

Edit: you can run with --debug to get the full error.

I just ran it with --whisper.encoderProvider=cpu --whisper.decoderProvider=cpu --debug but I get the same error.

I am using Windows

This is the output. I have redacted some parts, but not the last words.

It happens during the call to decode a single next token.

Based on the fact that it shows that other tokens were decoded before it, the problem isn't with initializing the decoder, it's with the actual decoding itself, which narrows it down.

I've tested the Whisper implementation with many different inputs. I've never encountered this particular error. Without a way to reproduce it I can't know what exactly causes it.

You could try to the Whisper recognition model on the same audio input and see if you get an error. Most likely you wouldn't.

If you don't get it, it could have something to do with the particular tokens that are decoded using the forced decoding. Maybe something about the language being Dutch. I don't know, maybe special tokens that are used there. It's really hard to determine.

You say it's common in the inputs you are trying. You can also try English inputs to see if it happens with them as well.

If you happen to have anything that produces this error that you can send, it will really help.

I just ran it succesfully with the Whisper small model. Seems to be a issue related to the tiny model specifically, then.

[cvl01]

Update: still getting the error on some files, although on less files when using small instead of tiny

[rotemdan]

It looks like a different exception.

DmlExecutionProvider means it's using DirectML (Windows GPU acceleration). I get a lot of errors with that provider but usually on other models, not Whisper. May be an issue with the ONNX runtime. They only added support for GPU processing on onnxruntime-node in the past few months.

[cvl01]

Then I'll try rerunning in cpu mode

[rotemdan]

The new 1.6.0 release now uses onnxruntime-node v1.19.2 instead of v1.18.x (previously).

Try to see if these issues still occur with the new version.

Anyway, based on my testing I've still never encountered them myself. It could be related to the particular combination of OS/hardware I'm testing on.

It's unlikely that a particular whisper model has an issue since these ONNX models are derived from the original ones from OpenAI.

Maybe something in one of the model's internal configuration (parameters like number of heads, constants, etc.) is triggering the issue, but not really causing it.
