speaker and mic project

[hong]

The below is just a simple block diagram, I want know if there is any other solution, want to have simple features for speaker and mic only.
This integration solution is being connected using LAN to the server, another alternative is connected through Power Line.

Do you all have any suggestion on how to develop this application? Any recommendation welcome.

Millions thanks!

if it is a prototype or a course project, you can start with some evaluation board/kit, then you do not need to make your own hardware and basic drivers. try the whole board as one component/or developing platform. you may start from IPC/ARM.

Thank you! I also see the Maxim's PowerLine Networking ICs.
How do I develop the block diagram of using PowerLine Networking ICs to speaker and mic? Do I need transmitter and reciever for the speaker and mic?
