Energy distribution in formant bands for arabic vowels

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...

Formant frequencies of Swedish vowels

Thresholds for second formant transitions in front vowels.

Formant dynamics in vowel nuclei contribute to vowel classification in English. This study examined listeners' ability to discriminate dynamic second formant transitions in synthetic high front vowels. Acoustic measurements were made from the nuclei (steady state and 20% and 80% of vowel duration) for the vowels /i, I, e, epsilon, ae/ spoken by a female in /bVd/ context. Three synthesis paramet...

Acoustic evidence for dynamic formant trajectories in Australian English vowels.

The extent to which it is necessary to model the dynamic behavior of vowel formants to enable vowel separation has been the subject of debate in recent years. To investigate this issue, a study has been made on the vowels of 132 Australian English speakers (male and female). The degree of vowel separation from the formant values at the target was contrasted to that from modeling the formant con...

Modeling vowels for Arabic BN transcription

This paper describes the LIMSI Arabic Broadcast News system which produces a vowelized word transcription. The under 10x system, evaluated in the NIST RT-04F evaluation, uses a 3 pass decoding strategy with genderand bandwidth-specific acoustic models, a vowelized 65k word class pronunciation lexicon and a word-class 4-gram language model. In order to explicitly represent the vowelized word for...
