Is it okay to extract words from audio files and then map them to form pseudo labels?

For example; if the extracted word is "so", it is mapped to "sow" as a pseudo label to be used in training

Yes you may.

With image classification, models pre-trained on imagenet are somewhat of a standard, and often built into popular libraries. For audio there isn't an exact equivalent.

Obviously, we don't want a situation where someone wins because of access to something the other participants didn't have. So in general sourcing, an extra dataset (even a public one) and using that to get an edge would be a potential issue. But if you have a dataset (or even better a pretrained model) in mind that you think would help all entrants, and it's public+free, let us know and we can see about adding it as an allowed source.

There are free+public speech to text models available in this python library

So can we use the above mentioned library?

It works for some audio files
