DeepSpeech Accuracy Issues and Newbie Questions

[ljohnson]

@reuben,

Thanks so much for your response. The information you provided is a monumental help.

@reuben

• How does training actually work under the hood?

• How do inferences work under the hood?

That’s quite a broad question, could you be more specific?

Let me be more specific as to my goal here. Perhaps the two questions asked here were too open ended. I thought that if I understood how DeepSpeech works a little better (how it uses the output graph and audio file to determine what said audio file’s transcript is, for example) it would help me to track down the accuracy issues I’m seeing.

Here is the result I got from our test file:

Specifically, I want to understand what would cause the long strings of seemingly random/psuedo-random characters with no spaces. As you can see from the above output I’m getting a few of them. Apart of from the audio file itself, is there anything that could cause this? I read in another thread here on Discourse, linked here, that this may be a known issue with DeepSpeech, but I want to know if there is anything I can check either when doing training (like settings, for example) or when doing inferences that can help alleviate this issue.

Thanks again for your help.
