Speech Science Exam 4--Kisenwether Chapter 6 (women & children's voices)

Fo differences between men and women are due to the dimensions of the ______ _______

vocal folds

Women have _____ vocal folds with _____mass which causes them to vibrate _____ at a_______ frequency and a ______pitch.

shorter/less/faster/higher/higher

Power differences between men and women are due to the ________ of _______

amplitude/vibration

What does open quotient mean?

the vocal folds are open longer during each glottal cycle

Women's vocal folds stay open _____ than closed, meaning that women's vocal folds are ______ longer from cycle to cycle then men's.

longer/apart

What reflects a difference in spectral tilt between men's and women's speech?

The amplitude of the first harmonic (H1) relative to that of the third formant (F3) is almost 10dB lower for males than females

Females then to have more spectral energy in the ______frequencies

higher

Why do women have more spectral energy in the higher frequencies than men?

difference in spectral tilt

Why are tracheal resonances a contributing factor as to why women's speech sounds different than men's?

The sound resonants differently between men and women due to different sizes of trachea (vocal tract)

Men's voices have a _____ amplitude because they are louder.

higher

Men's vocal folds see to move _____ from one another more than women's.

apart

In general, female vowels are associated with a ____Fo, ______ formant frequencies, ______formant amplitudes, ______ bandwidths and a ________ spectral slope.

higher/higher/lower/wider/steeper

Because women have a higher Fo, their spectral harmonics are more ______ spaced.

widely

Due to having a higher Fo which results in more widely spaced spectral harmonics, it makes it more difficult to determine _______ ________ for women's voices

formant locations

Because of the greater harmonic spacing, it is helpful to ______ the bandwidth for acoustic analysis women's speech.

increase

If you increase the bandwidth, you ____ the number of points in a FFT.

decrease

What is one acoustic correlate of breathiness in women's voices?

the amplitude of H1 relative to the amplitude of H2 is about 6dB stronger for women then for men.

Women are 4 times as likely as men to have a posterior glottal ______ during the closed period of the cycle

chink

When comparing the amplitude of H1 to the amplitude of H2 on 2 different spectrums (one male and one female), what should it look like?

the lines for H1 and H2 should be higher on the female spectrum than the male spectrum

As children grow, both Fo and formants _____ with age (for males and females).

lower

What are 2 reasons why Fo and formants lower as children grow?

1) The changing shape and length of the vocal tract 2) mass of the vocal folds

Children's formants are _____ than adults and Fo is higher due to ______ vocal tract

higher/small

The larger the vocal tract the _______ the formants will be

lower

The most dramatic change (lowering of Fo and formants) occurs at _______

puberty

Besides lowering of Fo and formants, what are 2 other changes that occur in children's speech?

1) productions become faster and more reliable 2) nasalization is reduced
