DIY sampler...

[Don Duval]

The main problem with using a voice recording circuit for music is the limited
bandwidth of the voice recording circuit. Usually, voice circuits have a max
frequency of 4khz or less and use a sample rate of 8khz. If you then want to
speed things up or slow things down, you will have to take care that filter
cutoff frequencies follow appropriately to avoid a nasty problem called
aliasing.

The triggering problem should be fairly straightforward, since these devices
are designed to record at the push of a button and play back at the push of
another.

For simple experiments, this seems like an excellent starting point, but will
have a few serious limitations
