Select the file and click "View and Edit” on the right side.Open the sound file in Praat (" Open" → "read from files…").You can follow the following standard procedure in Praat to analyze the stress. Since stress is manifested as rise in pitch, greater intensity (loudness) or greater vowel length, the analysis of stress must include various elements of acoustic analysis, like waveform, spectrogram, and pitch contour. at the bottom, the spectrogram indicates the greater length of the stressed syllable.in the middle, it shows the higher pitch shown in the pitch track.at the top, the waveform indicates the greater intensity of the stressed syllable.(See Figure 4.1).įigure 4.1 The waveform, spectrogram, and pitch contour of sound Loudness and quality have much less effect” (Roach 2009:74). Generally these four factors work together in combination, but experimental work has shown that these factors are not equally important the strongest effect is produced by pitch, and length is also a powerful factor. Prominence is produced by four main factor: (i) loudness (intensity), (ii) length, (iii) pitch (Fundamental Frequency/F0), (iv) quality. “All stressed syllables in words have one characteristic in common, and that is prominence. Stress plays an important role in communication, for it distinguishes different meanings when the stress is put in different positions. In English we usually find that simple words consisting of two or more syllables have a strong stress on one of these syllables and a weak stress on the remaining syllable or syllables.
