I have used the ISD2560, ie 60seconds, back in 2003. The ISD2590 is
obviously 90 seconds.
I found there to be quite a bit of learning involved, depending on how you
want to use it.
You can address the chip directly, but you have to know where the messages
are, you you do it per message, by skipping, but then you must keep tabs ion
message length and sequence.
I used a pic..

There are app notes and faq's on the net.

Are you looking to make a recording device or simply add voice to your
application?

If adding voice, check out the Text to Speech and the Silky Voice IC's from
Epson. I had a demo recently at a meeting with the Epson and the quality of
the S1V30341 was amazing. No need for any studio recording as they provide
you software to create the speech.

If you need Text to Speed then they have a chip that licenses the Dectalk. A
bit mechanical sounding as quite old technology but may be good enough for
some applications. I am using this in my current design.
