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?
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 $ 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!
