Do ‘Dominant Frequencies’ explain the listener’s response to formant and spectrum shape variations?

Determination of the vocal-tract shape from measured formant frequencies.

We model the vocal tract as a lossless acoustic tube and consider the relationship between the resonant frequencies and the cross-sectional area function. Empirical results show that if the logarithm of the area function is band limited preserving only 2n Fourier components, the lowest n pole and n zero frequencies of the admittance function measured at the lips uniquely determine the area coef...

The Shock Response Spectrum at Low Frequencies

The slope of the shock spectrum at low frequencies is typically evaluated by using a veIl known relationship between the undamped residual shock response spectrum and the 2agnitude of the Fourier.spectrum [1]. This has led to the common belief that the shock response of shocks with a low velocity change, like a ?yrotechnic shock, will have a low frequency .lope of 12 dB/octave. But anyone who h...

Formant Frequencies of Dutch· Vowels

In the present study Dutch vowel formant characteristics of laryngectomized tracbeoesophageal speakers are investigated.. Both vowels in CV nonsense syllables (/al, Iii, and /u/), and vowels of stressed syllables in read-aloud text are studied. It appeared that in the nonsense syllables the first formants were comparable to those ·of normal speakers, but that the second formants were higher tha...
