"Identifying Different Musical Instrument Sounds Using Fourier Analysis in LabVIEW" Rather than "ML" du jour, I would say that a fast Fourier transform would get you sufficient data to determine if practicing or talking or silence.

Definitely valid callout. I was also looking for an excuse to play with audio ML, but you're totally right that just examining a Fourier series could very likely do a great job of determining whether a given type of instrument is being played.

Which an FFT on an ESP32-S3 with it's Xtensa LX7 vector extensions can be quite fast
