IIRC, this has been requested in the past, but unsure if anyone posted it.
Twobob did most of the audio work for the KT (forum index: K5).
Including speaker independent voice recognition control of the K5.
The finished project includes flite for tts feedback.
But no recorder function (IIRC).
See:

and prior posts of that thread.
Note:
The package **was** at a now closed web-site.
I do have a copy of the release zip, in case anyone wants it posted again.
