Speech Recognition / Phoneme Extraction Tool:

Conversion of main processing code (including FFT) from C to C# - 100%.
GUI/code: Loudness Curve
GUI/code: Phoneme output
GUI
Updated frequency group definitions (312, 468, 562, 656, 750, 875, 1000, 1333, 1666, 2000, 2500, 3000, 4000, 5500, 8000)
Updated equal-loudness
New equal-loudness calibration for the first 16ms frame (+50%)
Removed last FIR filter @ 8000hz. Did improve frequencies (loudness) slightly but not enough to justify the processing time.
Combined Find Zero-Crossing function with Noise Find. Speed & quality improvement.
Replaced Hann window with a custom wide lobe cosine window/Inverse Blackman window.
Improved syllable finding
Updated Wav file loading

Satisfied now with the "Kay, Kee, Kai" test. 

Next target is finding "yes" & "no". This is part of the Google Speech Commands (Keyword Spotting) benchmark.
