In response to this post, I just open sourced a starter project to a variation of this idea: https://github.com/secretlessai/audio-mnist. I've been interested in doing image classification techniques like CNN on audio data for a while.

A couple years ago for a weekend project I made a simple "audio-mnist" dataset from handwritten digit audio recordings. I never got past a few days worth of work, but open-sourcing it has been on my mind for a minute. This post kicked me into action. Getting some more data, basic CNN examples, etc. could provide a nice starting point for a lot of research and tools.

There is still separate code I'd have to find and make intelligible to create the recordings and split the audio.

Anyway, in case anyone finds part of this process interesting or useful.
