A perception experiment on stop consonant voicing in (C)V1CV2 was conducted to test the effects of the preceding vowel. Five types of /ki/ as CV1 differing in closure voicing, vowel duration and vowel devoicing were spliced with a da-ta VOT continuum as CV2. Subjects’ judgment between the spliced kita and kida along a VOT range was compared with that of ta and da in isolation. Strong effects of...

This paper discusses two well-known phonetic-phonological phenomena of Japanese, vowel devoicing and mora-timed rhythm. Regarding vowel devoicing as a process of vowels getting consonantal, it may change the mora-templated syllable structures of Japanese, resulting in the deviation from mora-timed rhythm. To investigate spontaneous Japanese with comparison to other languages, the label data of ...

Vowel devoicing is a phenomenon that is reported to occur in many languages such as Japanese, Parisian and Montreal French, Turkish and English. This paper investigates vowel devoicing in Korean. A devoiced vowel does not exhibit characteristic vocal tract resonances, and instead is realized as a long interval of aspiration or frication following consonant release, resulting in non-distinct seg...

Most investigators agree that the acoustic information for American English vowels includes dynamic (time-varying) parameters as well as static "target" information contained in a single cross section of the syllable. Using the silent-center (SC) paradigm, the present experiment examined the case in which the initial and final portions of stop consonant-vowel-stop consonant (CVC) syllables cont...

HYPOTHESIS The purpose of the present study was to investigate the consonant recognition of Mandarin-speaking children with cochlear implants (CIs) and hearing aids (HAs) and to determine if they reach a level of consonant recognition similar to that of normal-hearing (NH) children. BACKGROUND Little information is available in the literature regarding the consonant perception abilities of pr...

In 1913, Anton Pfalz described a specific relation of vowel and consonant sequences for East Middle Bavarian dialects, located in the eastern parts of Austria. According to his observations, a long vowel is always followed by a lenis consonant, and a short vowel is always followed by a fortis consonant. Consequently, vowel duration depends on the quality of the following consonant. Phonetic exa...

Identification functions of 20 initial and 20 final consonants were characterized in 9600 randomly sampled consonant-vowel-consonant (CVC) tokens presented in speech-spectrum noise. Because of differences in the response criteria for different consonants, signal detection measures were used to quantify identifiability. Consonant-specific baseline signal-to-noise ratios (SNRs) were adjusted to p...

background: one of the most common complaints expressed by individuals with hearing-impairment is the difficulty in speech perception in background noise. different tests have been developed for the evaluation of reduced ability of speech perception in noise, and the consonant-vowel in noise test is one of the simplest one regard to speech materials. the goal of the present study was developmen...

Hearing aids (HAs) only partially restore the ability of older hearing impaired (OHI) listeners to understand speech in noise, due in large part to persistent deficits in consonant identification. Here, we investigated whether adaptive perceptual training would improve consonant-identification in noise in sixteen aided OHI listeners who underwent 40 hours of computer-based training in their hom...

This paper presents a compact graphical method for comparing the performance of individual hearing impaired (HI) listeners with that of an average normal hearing (NH) listener on a consonant-by-consonant basis. This representation, named the consonant loss profile (CLP), characterizes the effect of a listener's hearing loss on each consonant over a range of performance. The CLP shows that the c...
