PITCH ANALYSIS
The file recorded with my slower speech (a17.wav) was found from the ordered
list of speakers. Pitch analysis was conducted and relevant parameters were extracted.
The average pitch of the entire wav file was computed and found to have a value of
154.8595 Hz. The graph of pitch contour versus time frame was also created to see how the pitch varies over the wav file, Figure (3). The results of pitch analysis can be used in speaker recognition, where the differences in average pitch can be used to characterize a speech file. The code for this process can be found in Appendix D.
