The ISD1820 Recording Module
Voice Board is the real easy way to add Voice Recording (and Playback)
to your project. The Module can be operated directly by using the 3
Push-Buttons or with every microcontroller (ex. Arduino). A microphone
is implemented directly on the board, and you can connect any 8 Ohm
Speaker. Your recordings are saved even without power due to the
non-volatile storage on the ISD1820.

This
module uses the ISD1820 voice record and playback IC to record a single
voice message of up to 10 seconds in length. The recorded message is
stored in its specialised analogue flash memory that will keep the
message stored even when power is removed. The module includes an
electret microphone to record your message and push buttons allow for
record, partial playback, or full playback of the message. Header pins
allow for easy interface to a microcontroller and playback can be
controlled with just one digital pin.
