As the tongue moves forward...- The first formant decreases in frequency- The second formant decreases in frequency- The second formant raises in frequency- The first formant raises in frequency
Sonorant sounds are- Nasals, glides and liquids & Made with a less constricted vocal tract- Nasals, glides and liquids- Produced when the lips close completely- Made with a less constricted vocal tract
The corner vowels are /i, u, a, ʌ/.TrueFalse
Obsorption is " + " or " - " energy change?
Emission is " + " or " - " energy change?
Which is a voiced, velar, stop consonant?/k//d//g//v/
Problems with velopharyngeal function can result in air escaping through the nasal cavities rather than through the oral cavity during the production of oral sounds. The resulting speech production is characterized by- Hypernasality- Insufficient nasal resonance- Velopharyngeal closure- Hyponasality
Using the previous clinical case...Which result BEST characterizes how this partial paralysis has impacted your client's ability to phonate?- The vocal folds will vibrate normally- The vocal folds will no longer vibrate- It has produced a change in mass reactance- There is a reduced build-up of subglottal pressure
As a speech-language pathologist, you are referred a client, Mr. S., for voice treatment. The client's family has been complaining that Mr. S. is now very difficult to understand due to the severe weak and hoarse quality of his voice. In reviewing his case history, you noticed that he had a recent carotid surgery that resulted in injury to the vagus nerve, off of which the recurrent laryngeal nerve branches. This resulted in partial paralysis of one of his vocal folds. The ENT performed nasoendoscopy and revealed the cord situated in a paramedian position (close to but not at the midline of the glottis). The affected vocal fold was also bowed, indicating possible involvement of the superior laryngeal nerve as well, which innervates the cricothyroid muscle.Which aspects of the source-filter theory is most affected by this condition?- Source- Radiation- Filter- All of the above
Raising the tongue during phonation will...- Increase fundamental frequency- Decrease the first harmonic frequency- Decrease the first formant frequency- Increase the second formant frequency
The lowest tone to resonate in an open pipe of length L is 400 Hz. What is the frequency of the lowest tone that will resonate in an open pipe of length 2L?
The speed of an ultrasonic sound of frequency 45 kHz in air is 352 m/s. What is the air temperature?
Two adjacent sources each emit a frequency of 800 Hz in air where the velocity of sound is 340 m/s. How much farther back would source 1 have to be moved so an observer in front of the source would hear no sound?
A train is traveling away from you at 120 km/h. The train blows its 400 Hz whistle. What is the actual frequency of the whistle?
The frequency of a train horn is 500 Hz. What is the frequency heard by an observer if the observer is approaching the train with a speed of 30 m/s?
Two pure tones are sounded together and a particular beat frequency is heard. What happens to the beat frequency if the frequency of one of the tones is increased?
An observer approaches a stationary 1000 Hz sound source at twice the speed of sound. The observer hears a frequency of
Consider the standing wave on a guitar string and the sound wave generated by the guitar as a result of this vibration. What do these two waves have in common?
