Example Sentences:
Vowel
Definition:
(n.) A vocal, or sometimes a whispered, sound modified by resonance in the oral passage, the peculiar resonance in each case giving to each several vowel its distinctive character or quality as a sound of speech; -- distinguished from a consonant in that the latter, whether made with or without vocality, derives its character in every case from some kind of obstructive action by the mouth organs. Also, a letter or character which represents such a sound. See Guide to Pronunciation, // 5, 146-149.
(a.) Of or pertaining to a vowel; vocal.
Example Sentences:

(3) In addition, they were tested with dichotic listening for correct reports of consonant-vowel syllables.
(4) Test items in each of the 4 groups therefore contained different amounts of information regarding the nature of the following vowel, due to coarticulatory influences of the vowel on the preceding consonants.
(5) Coarticulatory effects of the vowel on the aperiodic portion were found to (1) occur early in the aperiodic portion, (2) vary with consonant and vowel, and (3) vary with vowel feature.

(8) Three male and 2 female subjects produced six repetitions of 12 utterances that were initiated and terminated by vowels and consonants of differing phonetic features.
(9) The perception of voicing in final velar stop consonants was investigated by systematically varying vowel duration, change in offset frequency of the final first formant (F1) transition, and rate of frequency change in the final F1 transition for several vowel contexts.
(10) These results suggest that Japanese monkeys process formant and pure-tone frequency increments differentially and that the same mechanisms mediate formant frequency discrimination in single-formant and vowel-like complexes.
(11) The major findings were as follows: (1) no significant difference was found in consonant identification scores between aperiodic, aperiodic + vocalic transition, and vocalic transition segments in CV syllables compared to those in VC syllables; (2) consonant identifications from vocalic transition + vowel segments in VC syllables were significantly greater than those from vocalic transition + vowel segments in CV syllables; (3) no significant difference was found in vowel identification scores between aperiodic + vocalic transition, vocalic transition + vowel, and vocalic transition segments in CV syllables compared to those in VC syllables; and (4) vowel identifications from aperiodic segments were significantly greater in CV syllables than in VC syllables.
(12) Comparisons between normalized spectral energy within a selected high frequency range revealed that energy within this frequency range for vowels produced by TE speakers was significantly higher than that produced by normal speakers.
(13) The amount of variability found in the labeling of speech contrasts may be dependent on cue salience, which will be determined by the speech pattern complexity of the stimuli and by the vowel environment.
