Description
1. Briefly explain about the following: [6 points]
• Corticulation
• Phonation
• Fundamental Frequency
• Epochs
• Formants
• Pitch
2. ”Female pitch is more when compared to Male pitch.” True or False. Justify the Statement
with proper explanation. [1 points]
3. What is speech ?? How speech signal is different from other signals? [1 points]
4. Record your mother’s name which should be as ”I am son of < mother’s name >” or ”I
am daughter of < mother’s name >”” which ever category you belong to. [6 points]
• Display the waveform
• Identify and mark the voiced, unvoiced, silence and plosive regions.
• Acoustic-phonetic description of the regions (MOA and POA)
• Time varing system description
• Spectral details for sounds units present in the waveform
Write a brief note on your observations. For this question you are expected to submit wave
file along with the annotated transcriptions. And all the acoustic-phonetic descriptions
have to be addressed in the tabular format. Note: Computer based question
5. Record your native place which should be as ”I am from < native place >”. [6 points]
• Display the waveform
• Identify the voiced, unvoiced, silence and plosive regions.
• Acoustic-phonetic description of the regions (MOA and POA)
• Time varing system description
• Spectral details for sounds units present in the waveform
Write a brief note on your observations. For this question you are expected to submit wave
file along with the annotated transcriptions. And all the acoustic-phonetic descriptions
have to be addressed in the tabular format. Note: Computer based question
Appendix
In the Acoustic-phonetic description following things are expected:
1. Consider the example of kitAb,
kitAb (/k/,/i/,/t/,/A/,/b/)
It is Unvoice unaspirated velar stop followed by front vowel followed by unvoiced
unaspirated dental stop followed by middle vowel followed by voiced unaspirated
bilabial stop.
For time varing system description following things are expected:
1. Consider the example of kitAb,
kitAb (/k/,/i/,/t/,/A/,/b/)
/k/ : Complete closure at velum position
/i/ : Tounge hump is high and is in front portion of vocal track (VT) system, VT
system is narrowly open
/t/ : Complete closure at dental position
/A/ : Tounge hump is low and is in back portion of VT system, VT system is widely
open
/b/ : Closure at lips
