Part 2: 4. Two waveforms and intensity traces are shown below for the same word ("cat"), extracted from the sentence "The cat walked towards the girl." In one version the word "cat" was stressed; in one version the word "girl" was stressed. a. On the waveform, mark the onset of voicing for the vowel and the onset of closure for the second stop (/t/) for each of the two words. Compute the vowel duration for each word (in s) by subtracting the time of the onset of voicing from the time of the onset of closure. b. On the intensity trace, measure the highest and lowest intensity for each word. Compute the intensity range (in dB) by subtracting the lowest intensity value from the highest intensity value. C. Use the information you gathered in (4a) and (4b) to fill in the table below d. Based on the information in the table and your notes and reading, decide if Word A is stressed OR Word B is stressed (circle one). List the reasons for your answer at the bottom of the page.
