Mel Frequency Cepstral Coefficients (MFCC) in C/C++
mfcc, speech-recognition, windowing
Solution
A recap in 2016:
- `libmfcc` is simple, MIT license, unsupported since 2010.
- YAAFE provides MFCCs and other features, LGPLv3, unsupported since 2011.
- Kaldi is overkill, but it can be used just for the MFCC. Apache License v2.0, and still supported.
- PocketSphinx is the CMU toolkit for speech recognition, CMU license (BSD-style), and still supported.
- SPTK is a research toolkit from Japan, Modified BSD license, and still supported.
- OpenSMILE has two licenses: (1) a flexible one for research and personal use, and (2) a commercial one.
Note I mention PocketSphinx, instead of Sphinx, as the latter is written in Java.
Problem
Is there any implementation of MFCC available in C/C++? Any source codes or libraries? I've already found http://code.google.com/p/libmfcc/ which seem to be good.
