Example of AM-based phase analysis for the nursery rhyme sentence “Mary Mary quite contrary”. The acoustic waveform of the sentence is shown in black. The extracted Stress, Syllable and Phoneme AMs are shown in red, green and blue respectively below. Hand icons represent the hypothetical occurrence of the 4 taps. For each tap, the instantaneous AM phase at the point of occurrence (yellow dot) was measured.
