Automatic Speech Recognition Feature Extraction Using OpenCL Improvements

Implemented using Intel OpenCL SDK.

Prerequisites:

libsndfile
FFTW(Pure CPU run for benchmarking an OpenCL run)
Intel OpenCL SDK, with 2.1 support preferable. Run in x86 mode for Intel GPU support.

P.S: Benchmarking features have been planned, at least against an existing pure CPU based implementation using FFTW library for CPU based FFT. For running that, it will obviously become a prerequisite. Until you specifically want to use it, I'm trying to keep it free from that pre requisite.

Task Lists:

• Code Added
• Segmenting of soundfile
• FFT using AppleFFT
• Normalise and Filterbank
• DCT
• Delta and Delta-Delta
• Soundfiles Added
• Output Files Added
• Joining all modules for 'End-to-End'
• Add support Links for troubleshooting
• Add methodology documentation
• Add report and detailed documentation
