Guideline for Specific Version of Deepspeech

DeepSpeech
#1

Hi everyone!

There is constantly changes in Deepspeech versions. I installed Deepspeech 0.2.1 alpha in September 2018. Up till now, Deepspeech 0.4.1. has been released.
I am wondering how to keep track of a specific version.
Its becoming a big confusion. Kindly help.
Or Anything better which can be recommended to developers.
Thank you!

You can always find which release is the most recent by looking at the GitHub DeepSpeech releases page.

Alternatively you can just update, say, your python package

pip3 install deepspeech --upgrade

to get the latest version.

What help are you looking for ?

I am using DeepSpeech 0.2.1 alpha 0. For English Language, it doesn’t decode English sentences with any spaces.
For Urdu Language, it stuck on the very first character of my vocabulary.
I want to see the Github DeepSpeech release page for DeepSpeech master 0.2.1 . But the latest version come out with ctc decoder, which I had not been using for previous versions.

#6

We never published a stable 0.2.1, we moved to 0.3.0, because of a change breaking backward compatibility.

Mostly it decodes correctly but without any spaces.

#10

This is a bug we fixed by moving to ctcdecoder …

#11

This is what I was figuring it out. Thank you for the help. :smile:

#12

Can somebody share the complete training guide of DeepSpeech 0.4.1 ?
guideline with data files format and how many files are needed ?
Like, Does it need vocab.txt, binary trie file ?
Or everything to train from DeepSpeech 0.4.1
thank you!

I am having this error though I install ctc decoder. using
pip3 install $(python3 util/taskcluster.py --decoder)
I am also missing trie file in DeepSpeech 0.4.1 I don’t know how to generate it.
Thank you for the help.

Well, the error shows you don’t have the module installed … Maybe messing around your virtualenv ?

Please refer to the documentation.

Hi, Does any version of Deepspeech works on Ubuntu 14.04 and supports cuda 8 rather than cuda 9?
I searched but I couldn’t get the specific answer.
