#31

@lucifera678 Can you use proper code formatting for console / log output ? It’s complicated to read otherwise.

#32

Again, can you share your changes ?

#34

Please, this is absolutely not useful. Can’t you git diff and share the changes appropriately using code formatting ?

#35

@lucifera678,
40s sequences to train are very large !!
You took a lot of time to train your model, however you obtain a wer. 99!!
99% error !!
It’s normal that the results are poor…

Sure that you should try training with only 10 sentences, 16k mono, max 15s… See the results…correct the params… Anderstand…

And restart later with all your datas.
Good luck
Vincent

All the Bold formatted text are the changes in the files as you said me to change 16000 to 44100

#39

I’m sorry, that’s still not a diff as I asked. It’s completely unusable.

#40

@lucifera678 maybe you aren’t aware what a diff is? If not, one of these might give you a bit of background:

https://www.git-tower.com/learn/git/ebook/en/command-line/advanced-topics/diffs

#41

Could you upload your data somewhere? I could try to train a model and give you the config you need. Feels like that’s easier than debugging such specific issues.

#42

@lucifera678
ok ok listen here. go to util/flags.py . change audio_sample_rate to 16000(you set it as 44100). and then you’ll see that you can export your model.

Do i know if that screws up your model? I do not. But can you export it? yes. good luck.

Resample training input samples to align with inference restraints
#43

Is there restriction for wav file length for training?

#44

You want to use data with max length 15 seconds, optimally even less than that (Mozilla model is trained on files with max length 8 seconds if I recall correctly).

More on how to deal with it here: Longer audio files with Deep Speech
Moreover in DeepSpeech source code in examples there are some scripts where vad transcriber was presented.

after training my model i tested it and its giving me this error

#46

@sehar_capricon Please please please, can you really make an effort and USE CODE FORMATTING ? Your output is hard to read, this is DIFFICULT for people to help you.

You are running binary v0.5.1, your error would suggest you trained from current master which targets v0.6.x binaries.

#47

thanks for your prompt response,
i have trained my model on deepspeech v 0.5.1

#48

Can you triple check that ? How did you performed the export ?

#49

you can improve the accuracy of your model by changing the audio file length to be between 15 to 20 seconds
