background and aim: aging is accompanied with changes in cognitive capacities. in spite of advances in neural imaging technologies, there is not a straightforward method to observe cognitive functions. for assessing brain functions, researchers mainly use psychometric tests. the aim of this study was using consonant-vowel (cv) dichotic test as a non-invasive behavioral test for auditory attenti...
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...
Vowel quality perception in quantity languages is considered to be unrelated to vowel duration since duration is used to realize quantity oppositions. To test the role of microdurational variations in vowel category perception in Estonian listening experiments with synthetic stimuli were carried out, involving five vowel pairs along the close-open axis. The results show that in the case of high...
Acoustic measurements were conducted to determine the degree to which vowel duration, closure duration, and their ratio distinguish voicing of word-final stop consonants across variations in sentential and phonetic environments. Subjects read CVC test words containing three different vowels and ending in stops of three different places of articulation. The test words were produced either in non...
Background and Objective: One of the most important physical properties of vowels is their formant structure. One of the most obvious speech errors in hearing-impaired children is vowel errors. The present study aimed to determine and compare the formant structure of Persian vowels in deaf and cochlear implant children in the age range of 4-7 years. Materials and Methods: This descriptive-anal...
Objectives: Voice is influenced by personality. However, it is still questionable which acoustic features are influenced by personality traits. This study aimed to investigate the relationship between acoustic characteristics and personality dimensions. Methods: Thirty-three participants with dysphonia and 33 participants without dysphonia were recruited to take part in this cross-sectional st...
Vowel perception ability for 16 prelingually deafened children using Nucleus 22-channel cochlear implants was studied at 12, 24, and 36 months postimplantation. Information transmission analysis was used to evaluate the effectiveness of the implants in conveying the essential cues required for accurate vowel identification and whether the cues used varied with experience or device use. Individu...
this paper addresses the validity of two hypotheses concerning changes of vowel quality in persian. the theory of centralization claims that there is a strong correlation between vowel duration and vowel quality. as vowel duration is shortened in unstressed contexts, the size of the vowel inventory reduces toward the center, leading to considerable overlap between different categories and a red...
A series of experiments was conducted to determine (1) the accuracy with which vowel segment durations in spoken sentences can be represented in auditory sensory storage and (2) the extent to which phoneme boundaries in the identification of phonemic vowel length in Dutch are affected by syntactic and/or auditory-phonetic context. In a preliminary production test it was found that durations of ...
