First formant difference for /i/ and /u/:
The value of the first formant of high back and high front vowels (/u/ and /i/) has been determined for near minimal pairs in a 30-language sample. It is found that for 29 out of 30 languages the average of the first formant is higher for high back vowels than for high front vowels, and that for 26 out of 28 languages the majority of minimal pairs has a high back vowel with higher first formant...
متن کاملDifference in second-formant transitions between aspirated and unaspirated stop consonants preceding [a].
Perceptual experiments with synthetic speech have shown that the category boundary on an acoustic (pa}-(ta) {/ba/-/da/} continuum (obtained by varying the onset frequencies of the second and third formants) is closer to the labial endpoint than the boundary on a (pha}_(tha) {/pa/-/ta/} continuum. Of several possible explanations, the most plausible seems to be that natural unaspirated and aspir...
متن کاملFormant transitions in varied utterance positions.
AIM Acoustic characteristics associated with varied utterance positions were examined to understand the acoustic consequences of potential articulatory changes near utterance boundaries. METHODS Second formant transition characteristics, including transition duration (ms), transition extent (Hz), and derived slope of transition (Hz/ms), of 12 healthy speakers of American English were examined...
متن کاملThresholds 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...
متن کاملFrequency difference limens at high frequencies for normal-hearing and hearing-impaired subjects
The smallest detectable change in frequency of a pure tone (the difference limen for frequency, DLF, expressed as ∆f/f) may depend on two mechanisms: a place mechanism based on the filtering within the cochlea [1] and a temporal mechanism based on the patterns of phase locking in the auditory nerve to the “temporal fine structure” (TFS) evoked by the tone [2]. The precision of phase locking wea...
