22
Q

Sound Source for Vowels & Resonant Consonants

A

Phonation in larynx

sound source= quasi periodic

23
Q

Sound Source for Fricatives and Stop Bursts

A

Voiceless = aperiodic

Voiced = both aperiodic & quasi periodic

24
Q

Diphthongs

A

Position changes during production.

25
Q

Intrinsic Tongue Muscles

A

Shape Tongue Body

bunch, flatten, curl tip

26
Q

Extrinisic

A

Move the Tongue body

forward, back, up down

27
Q

Typical Vowel Acoustics

A

Voicebar = fundamental frequency, 100-300 Hz

F1 < 1000 Hz ~250-900 Hz

F2 800-2500 Hz

F3 is above 2000 Hz usually around 3000 Hz

28
Q

Typial Male Vocal Tract length

A

17 cm

F1 = 506 Hz

F2 = 1518 Hz

F3 = 2530 Hz

29
Q

Define Dysarthria

A

Group of neurological disorders in which muscles become weak or paralyzed or articulations become uncoordinated

30
Q

Dysarthria effects on Vowels

A

Longer duration (slower speech rate)

smaller vowel space (less tongue movement)

31
Q

Hearing Loss effects on Vowels

A

Reduced vowel space (esp F2)

32
Q

Antiresonances

A

Filtering effect resulting in loss of acoustic energy in particular frequency region

33
Q

Nasal Murmurs

A

low & strong F1 on spectrogram
