There are some for Windows Mobile 2003 or later, but those require a higher version of CE than the 3.0 on which H/PC 2000 is based.
(NoteM comes to mind, but in addition to requiring CE 4.2 or later, it also requires mfcce300.dll, doclist.dll, and gx.dll.
)
Which version of Resco Voice Recorder are you using
(eg, 4.60
)? I'll check it out myself later when I have some time.
