Master's thesis, Harvard Extension School.https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37365423In this project, I implemented a suite of software tools to demonstrate the feasibility of a speech audio processing application, i.e. automatic classification of conversational speech situations. First, I re-implemented a classical pitch tracking algorithm for speech processing - the RAPT algorithm (A Robust Algorithm for Pitch Tracking, Talkin 1995). Next, I collected and analyzed a novel corpus of podcast speech audio samples. Finally, I created an application-specific classification algorithm and evaluated its performance.application/pdfspeech processing, situation classification, pitch extraction, pitch estimation, algorithm performance evaluationThesis or Dissertation2020-09-29
