Hoi,  you really have to Google for "sound recognition" there are too many chips available for that purpose. And many of them are outdated, so first read datasheets to findout what you really need (or want).

There is a application note in atmel website about recording voice using AVR and flash memory
Search at atmel site.

Good luck

You can use VR Stamp  here is PDF: http://www.sagitron.es/data_sheet/sens0504.pdf

When I have that client request I use

Easy-VR Stamp development system is a full-featured development board for the Sensory VR Stamp modules. It was designed to allow students or engineers to easily exercise and explore the capabilities of the VR Stamp voice recognition modules. It allows the VR Stamp modules to be interfaced with external circuits to a broad range of the peripheral devices, allowing the user to concentrate just on the software. Figure on the left illustrates the first contact with the development system. On a silkscreen there are marks beside every component. These marks describe connection to voice recognition modules, operation modes, and some other useful notes. As a result, need for additional schematics is minimized, because all information are already on the board.

yes its have price about 99 euro but you can easy make what you need without problem... Its dependent of your request, what you need and for applicable....

or if you dont like to use development system you can use VR Stamp Toolkits

her is link http://www.sensoryinc.com/products/vr_stamp_toolkits.html

The VR Stamp™ ToolKit contains everything necessary to program the VR Stamp to your specifications. Application programs are downloaded onto the VR Stamp module using a Module Programmer Board that has been connected to a PC’s USB port. The VR Stamp can then be removed and plugged directly into the final product using an industry standard DIP socket.

The VR Stamp Toolkit includes samples and demos of key Sensory technologies that make developing with speech easier than ever. Tools like QuickSynthesis™ 4 allow recordings of speech to be compressed quickly with the right combination of size and quality.

Phyton provides an Integrated Development Environment including Assembler and Linker as well as a limited-life C compiler. All of the world-class technologies in the FluentChip library are available for use on the VR Stamp, with the exception of Record & Play due to memory constraints.

Have nice time
