sometimes srt file not generated

[iorilu]

I tried a few files, sometimes srt file not generated, I used --output_format srt

I also try to debug it , and set breakpoints at following lines , find it may never reach here , and no error or exception, it's strange.

            writer = get_writer(output_format, output_dir)
            writer(result, audio_path)

Hello. Yes, some of users reported this before. Which operating system are you using? Are you using CUDA or CPU? Thanks

[iorilu]

I am using windows 10 , has 3060 GPU , and use miniconda as environment

GPU is working , just srt file not generated

one other issue is live_transcribe also not work as expected, no response after run live mode, it seems volume is too small, i changed Threshold = 0.01 , then program start to work , but recognized very poor result

same problem! i can see all the transcription results, but sometimes no output.

for me ,short files like under 10mins, and when using --model small(by default),all goes fine and show "Transcription results written to 'D:\test' directory", then srt files can be found in current folder. but when using --model tiny or other models, no output at all after transcripting complete, just stopped, no error tips.

And for files like 30mins or longer , no model that i tested can genrate srt files.

cuda toolkit:11.8, cudnn: 8.2, torch,'1.11.0+cu113' zlibwapi.dll and cudnn path proper set.. whisper-ctranslate2 version: up-to-date.

the transcripting is indeed a lot more faster, do hope this tiny error can be clear and fix:)

Can you try the live transcription providing the language? Since the audios are short, this usually improves a lot. Can you confirm is this makes any difference for you? Thanks

@seset

My current hypothesis is there is a problem with CTranslate2 and GPU on Windows due to CUDA or CTranslate2.

In order to validate or invalidate this hypothesis I will ask you if you can try to run this simple code:

1. Download https://raw.githubusercontent.com/jordimas/calaix-de-sastre/master/faster-whisper/inference.py
2. Edit the file and change "file.mp3" for your file
3. Run in using python3 inference.py

And tell me if you can reproduce the problem with this simple code. Thanks

[iorilu]

the code seems no problem with me

I just tried the latest version (0.22) , and providing the language english(en) and chinese(zh) , if use the default setting , Threshold = 0.2 , still can't record anything , I am not sure if it's the micphone issue , i just use laptop mic

i adjust Threshold=0.05, now the program has response, but the effect is very poor compare to normal transcribing a video, is this normal?

by using py and no output at all no matter which model to use.. also i tried faster-whisper directly in other venv and encourted same problem , can you please advise the excat cuda toolkit and cudnn version you use, as well as the torch,torchvison , i do want try to get this nice codes work first.

In the next version it will be possible to adjust the volume threshold https://github.com/Softcatala/whisper-ctranslate2/commit/0023a2eea6de76c0d6bf646266dfd4d7371e7155. You will not need to edit the code.

Have you tried specifying the language and using the same model that you use for file transcription?

[iorilu]

yes，i specified language en and zh, no improvement

[jordimas]

Version 0.2.6 should fix this.
