Honored ContributorWell, I guess there are endless possibilities :)
You could write the data to SRAM/SDRAM/FLASH, transmit it over a TCP/IP socket connection, save it to a .WAV file on an SD-card - lots of different ways to manipulate it. Since the data is in digital format, you could write C/C++ functions to perform DSP or even use RTL functions written in VHDL/Verilog to peform on-the-fly signal processing. With Speech, you can even venture into the real-time of basic voice recognition and vocal matching. I have attached a couple of links below you may find interesting.
