Would it be possible to add a simple speech encoder/decoder

Hi, nice that we get our own set of audio decoders.
I would love to see if we could add a simple speech encoder/decoder as well for when we use something like espnow to transfer speech audio, could this be added?

I wouldn't be opposed to adding this if someone contributes it, but it isn't a priority for me to work on.
