Detect Fundamental Frequency (Pitch) in speech

• Praat: Run Praat script on a test speech signal, log detected Fundamental Frequency F₀ to file as reference.
• MATLAB: Pre-Processing: Use Threshold in time domain to segment the voiced speech.
• MATLAB: Use Cepstrum processing on voiced speech to detect Pitch i.e. Fundamental Frequency F₀.
• Pitch Detection done using: Threshold, Median and Non-linear Filtering.
• Compare graphs of resulting F₀ contours detected in MATLAB and Praat as referent tool.

Praat scans the test files folder for .wav files and saves Timestamps and F0 (Pitch) [Hz] in .txt.
Run src/praat_batch.bat

(check Praat data in MATLAB with src/test_read_praat_output.m)

Run src/main.m Cepstrum quick reminder:
