Part 1:

• Step1: Choose an example from one of the languages provided

• Step2: Click on 'Play/Pause' button and observe the audio/wave file sounds.

• Step3: Study the difference using the 'Change Band' dropdown option (wideband and narrowband spectrograms) for different window sizes.

• Step4: Verify the segmentation boundaries for various subword units (words, syllables and phonemes).

• Step5: Verify that transitions between adjacent sound units from the formant contours observed from the spectrogram.

• Step6: Identify/locate voiced/unvoiced/plosive/silence regions from the spectrogram.

• Step7: Observe the time varying excitation and system characteristics from the spectrogram.

• Step8: Write a brief note on the observations.

Part 2:

• Step1: Choose an example from one of the languages provided.

• Step2: Click on 'Play/Pause' button and observe the audio/wave file sounds.

• Step3: Mark the boundaries of subword units (words, syllables and phonemes).

• Step4: Look out for a message which pops up if the entered boundary value is incorrect.

• Step5: Write a brief note on the observations.
