SHS 375 EXAM QUESTIONS WITH All CORRECT ANSWERS UPDATED It is much harder to guess the gender of 100 year old person based on his/her speech than a 40 year old person - Answer- true T/F it is much harder to guess the gender of a 100 year old person based on his/her speech than a 40 year old person - Answer- true the shape of the laryngeal waveform determines () of the sound - Answer- -timbre -a 'jagged' waveform (large skewing quotient or small open quotient) represents sudden c...

Source filter model (4) - ACCURATE ANSWER~ the larynx serves as the sound source and its output is then sent into the vocal tract which filters it. ~ larynx on its on cant produce any sound unless there is pressure driving it ~ pressure comes from the lungs ~ vocal tract doesn't just filter but resonates or enhances some sounds Pitch (2) - ACCURATE ANSWERStretch the vocal folds to increase their tension and therefore increase the frequency at which they will vibrate ~ Contracting the cri...
