in terms of acoustics • RECOGNIZE and ANALYSE the features of stops, fricatives and affricates acoustically.
Topic-198: Stop Voicing on Spectrograph There are three important acoustic correlates of voicing in stops the voice bar, VOT, and the duration of the preceding vowel. Record /apa/, /aba/, /ata/, /ada/, /ap ha and at ha and for
each of the stops in the file, take the three measurements according to the following instructions Seethe voicing or the voice bar by exploring features of stop. We can also explore the features related to the place of articulation (any bilabial feature for p orb in comparison with non-bilabial). Also check the duration of the preceding vowels. Note down the presence of voicing. Now try to answer the following questions
1. Do you seethe voice bar If the
voice bar is present at all, does it last through the duration of the closure Why do you think it might go away
2. Can you point out the features related to the place of articulation Comment on them.
3. How about the duration of the preceding vowel
Is it affected by the voicing Share with your friends:
