Mozilla Deepspeech has been around for a while (https://github.com/mozilla/DeepSpeech https://github.com/mozilla/DeepSpeech). In fact, this code looks like it heavily copied from there (see attribution notices in comments). Their examples use much less data, just 5 utterances from the Librispeech training set. Which is perfectly fine for a tutorial, since training on 1500h worth of speech data takes from several days to multiple weeks, depending on your hardware. [edit: IMHO, the tutorial from the Bay Area DL School is more useful to get started: https://github.com/baidu-research/ba-dls-deepspeech) https://github.com/baidu-research/ba-dls-deepspeech)]
