I found a MFCC library in GitHub and explored it a little bit. It directly takes a wav file as input and returns one N*1 array (a sequence of acoustic vector). I recorded my voice and converted to a wav file. I briefly tested the code. It took my wav file and return an array containing a sequence of vectors. I will use this library in my project. But there are many related factors that i need to study. I also wrote the timeline for the rest of this semester and next semester. My next step is to keep working on this MFCC library and explore the Dynamic Time Warping library in GitHub. <\/p>\n","protected":false},"excerpt":{"rendered":"
