Different speakers produce the same speech sound differently, yet listeners are still able to reliably identify the speech sound. How listeners can adjust their perception to compensate for speaker differences in speech, and whether these compensatory processes are unique only to humans, is still not fully understood. In this study we compare the ability of humans and zebra finches to categoriz...

Temporal-order perception of phoneme segments in running speech is much superior to temporal-order perception in repeating vowel sequences. The more rapid rates possible in running speech may be due largely to the presence of formant transitions. In a series of five experiments we observed that many temporal-order misjudgements of repeating vowels can be explained in terms of auditory stream se...

Schlieren imaging enables real-time visualization of airflow through refraction of light. The potential of schlieren imaging for speech research was first proposed nearly 40 years ago [1]. A recent study tested this proposal [2]. Phonetically trained raters coded schlieren recordings of French vowels as oral versus nasal [2] (Figure 1). Although raters discriminated between the oral and nasal v...

This acoustic experimental study investigates the influence of dialectal background on perception and production lax-tense vowel distinction in English learning from theoretical standpoint language transfer. Previous studies usually regard first as a source transfer, with few considering dialect process while this has taken account participants’ dialects biological genders look at whether how C...

Of the Taiwanese participants, only one showed any significant speech rate effect (t = 1.88, p < .05 for the first vowel of the tokens; t =2.29, p < .025 for both vowels combined). One other showed no speech rate effects whatsoever, instead inconsistently devoicing some tokens, while the third did not devoice any vowels within the tokens, instead only devoicing a small number of sentence-final ...

The aim of the present study is two-fold. First, we will show that glottal stops/glottalization and low vowels are likely to co-occur in typologically different languages. Second, we will investigate the question whether this widely attested cooccurrence of glottalization and low vowels could be due to a perceptual phenomenon; i.e. differences in the perception of vowel quality of glottalized a...

BACKGROUND/AIMS This study examined the spectral characteristics of American English vowels in dysarthria associated with cerebral palsy (CP), and investigated the relationship between a speaker's overall speech intelligibility and vowel contrast. METHODS The data were collected from 12 American English native speakers (9 speakers with a diagnosis of CP and 3 controls). Primary measures were ...

To investigate acoustic feature differences between Japanese nativeand non-native speakers in spoken Japanese, 29 Japanese words were digitally recorded by 10 each of Japanese, French, Korean, Thai, Taiwanese, and Vietnamese speakers. The results revealed that acoustic features in each language have different tendencies in relative duration, intensity, and fundamental frequency. For example, co...
