Analysis and recognition of Korean isolated vowels using formant frequency.

Formant frequency analysis of children's spoken and sung vowels using sweeping fundamental frequency production.

High-pitched productions present difficulties in formant frequency analysis due to wide harmonic spacing and poorly defined formants. As a consequence, there is little reliable data regarding children's spoken or sung vowel formants. Twenty-nine 11-year-old Swedish children were asked to produce 4 sustained spoken and sung vowels. In order to circumvent the problem of wide harmonic spacing, F1 ...

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...

Analysis of intraperiodic formant modulations in spoken and sung vowels

Intraperiodic formant modulations in spoken and sung vowels from four Finnish male opera singers were analyzed by using analytic filtering method and modified covariance type of linear prediction. Both methods revealed clear formant modulations. Differences were seen between spoken and sung samples and between individuals.

Formant frequency estimation of high-pitched vowels using weighted linear prediction.

All-pole modeling is a widely used formant estimation method, but its performance is known to deteriorate for high-pitched voices. In order to address this problem, several all-pole modeling methods robust to fundamental frequency have been proposed. This study compares five such previously known methods and introduces a technique, Weighted Linear Prediction with Attenuated Main Excitation (WLP...
