Modeling Vowel Normalization and Sound Perception as Sequential Processes
This study constitutes the first attempt at combining vowel normalization procedures with the linguistic perception framework of Stochastic Optimality Theory [1] and the Gradual Learning Algorithm [2]. Virtual learners possessing different normalization procedures, and a control learner with no normalization, were trained to perceive Brazilian Portuguese and American English vowels. Our results...
متن کاملAuditory contrast and speaker quality variation in vowel perception.
Selective adaption and anchoring effects in speech perception have generated several different hypotheses regarding the nature of contextual contrast, including auditory/phonetic feature detector fatigue, response bias, and auditory contrast. In the present study three different seven-step [hId]-[h epsilon d] continua were constructed to represent a low F0 (long vocal tract source), a high F0 (...
متن کاملNon-uniform vowel normalization
A study of female-male differences in F F2: and F3 of var ious vowels within eight different languages revea ls univer sa l tendencies of departure f rom a simple uniform scaling. These have been quantified and adopted a s a basis for a vowel-category-specific normalization procedure which, on the average, reduces the female-male variance to one-half of that remaining after a simple uniform sca...
متن کاملComparing Vowel Formant Normalization Methods
Results from a large-scale comparative study of vowel formant normalization methods are presented. Effectiveness of methods was evaluated by their ability to improve the equalization and alignment of speaker vowel spaces over raw Hertz measurements. Vowel-intrinsic methods performed poorly, while vowel-extrinsic, formant-intrinsic methods performed the best overall.
متن کاملAsymmetries in vowel perception
Asymmetries in vowel perception occur such that discrimination of a vowel change presented in one direction is easier compared to the same change presented in the reverse direction. Although such effects have been repeatedly reported in the literature there has been little effort to explain when or why they occur. We review studies that report asymmetries in vowel perception in infants and prop...
