I'm making a project in DSP, which aims to do various operations on
the speech, like combining two speech signal, volume control,
filtering. I'm  confused about which processor to use. Could u please
guide me which processor will be best suited to me?

If your application is not necessarily portable, battery driven or wireless, use a
personal computer or Apple McIntosh, any C++ compiler and the Steinberg VST SDK, see:
http://ygrabit.steinberg.de/~ygrabit/public_html/index.html . 

Dedicated DSP platforms need their hardware environment that is often tailored for a specific
application, especially if it has to fulfil the said requirements. In former times we used DSP
cards for personal computers to do audio and video signal processing - today most times this is
done natively on the CPU.

I purchased a cheap version of µ$ Visual C++ .net Standard compiler (if you want to buy a DSP C
compiler this is by far more expensive and more complicated to get some results) and signed for
a VST SDK license (for free). It took me a week only to get my complete DSP application running
- this is really straightforward (we outsourced the GUI what took another year). There are
various host software platforms available that can run Steinberg VST plugins. 

If you ask which processor is the best suited you have certainly no preference for a dedicated
architecture and do probably do not want to learn the details for that... if you want to get an
expert in the DSP software/hardware codesign - welcome to the community!
