Visualisation-of-Speech-data

Visualisation of speech data

1. Initially I have shown the Amplitude VS Time plot of a speech data
2. Then I have shown the probability density of the amplitude values
3. Then I have shown the Amplitude Envelope of the Amplitude VS Time plot
4. Then I have hown the DFT (Discete Fourier Transformation) and STFT (Short Time Fourier Transformation)
5. Then I have shown the Spectrogram Generation of the speech data
6. I have also shown the pitch contours of the spectrogram using Parselmouth python library
7. Finally I have shown the F0 fundamental frequency plot and harmonic spectral envelope (smoothed spectrogram) using WORLD analysis

Python libraries that I have used

For speech analysis

1. librosa
2. parselmouth
3. pyworld
4. pysptk

For visualisation

1. matplotlib
2. seaborn

Github personal repository update

1. git clone
2. cd to the folder
3. git init
4. git add ... (git rm for remove)
5. git remote add origin https://github.com//.......git
