Hmm, well it looks like I read the wrong line of the dimensions. It's=20
actually 10x18mm including leads.

Digi-key had the ISD4002 part in single quantity when I checked a minute=20
ago, but all I saw were 28-pin devices.  The dsPIC was still a bit=20
cheaper, if you can replace any of the other parts with it.  Also, the=20
output impedance on the winbond part was 5kohm, so I suspect an audio=20
amp will be necessary.
