The Praat waveforms: Two listening conditions. The waveforms depict the phrase “wash your hands” from the medipatch vignette. The two listening conditions: (A) 0.97 s, original format, conversational speech technique (196 spm); (B) 1.24 s, spoken with clear speech technique (152 spm). Note in clear speech, the temporal-spectral enhancement can be appreciated by the increased durations of the vowels and increased amplitudes of the waveform.
