Purpose: This study is to investigate whether Cantonese-speaking musicians may show stronger CP than Cantonese-speaking non-musicians in perceiving pitch directions generated based on Mandarin tones. It also aims to examine whether musicians may be more effective in processing stimuli and more sensitive to subtle differences caused by vowel quality.Methods: Cantonese-speaking musicians and non-musicians performed a categorical identification and a discrimination task on rising and falling continua of fundamental frequency generated based on Mandarin level, rising and falling tones on two vowels with nine duration values.Results: Cantonese-speaking musicians exhibited a stronger categorical perception (CP) of pitch contours than non-musicians based on the identification and discrimination tasks. Compared to non-musicians, musicians were also more sensitive to the change of stimulus duration and to the intrinsic F0 in pitch perception in pitch processing.Conclusion: The CP was strengthened due to musical experience and musicians benefited more from increased stimulus duration and were more efficient in pitch processing. Musicians might be able to better use the extra time to form an auditory representation with more acoustic details. Even with more efficiency in pitch processing, musicians' ability to detect subtle pitch changes caused by intrinsic F0 was not undermined, which is likely due to their superior ability to process temporal information. These results thus suggest musicians may have a great advantage in learning tones of a second language.

ABSTRACTWe intended to establish if two lexical tone contrasts in Zhumadian Mandarin, one between early and late aligned falls and another between early and late aligned rises, are perceived categorically, while the difference between declarative and interrogative pronunciations of these four tones is perceived gradiently. Presenting stimuli from 7-point acoustic continua between tones and between intonations, we used an identification task and a discrimination task with an experimental group of native listeners and a control group of Indonesian listeners, whose language employs none of the differences within either the falling or the rising pitch contours in its phonology. Only the lexical condition as perceived by the experimental group yielded sigmoid identification functions and a heightened discriminatory sensitivity around the midpoint of continua. The intonational condition in the native group and both conditions in the control group yielded gradient identification functions and smaller, reverse effects of the continuum midpoints in the discrimination task. The results are interpreted to mean that sentence modality contrasts can be expressed gradiently, but that lexical tone differences are represented phonologically, and hence are perceived categorically, despite low phonetic salience of the contrast. This conclusion challenges assumptions about the relation between linguistic functions and linguistic structures.

The study investigates the perception of vowel length contrasts in Cantonese by native Mandarin speakers with varying degrees of experience in Cantonese: naïve listeners (no exposure), inexperienced learners (~1 year), and experienced learners (~5 years). While vowel length contrasts do not exist in Mandarin, they are, to some extent, exploited in English, the second language (L2) of all the participants. Using an AXB discrimination task, we investigate how native and L2 phonological knowledge affects the acquisition of vowel length contrasts in a third language (L3). The results revealed that all participant groups could discriminate three contrastive vowel pairs (/aː/–/ɐ/, /ɛː/–/e/, /ɔː/–/o/), but their performance was influenced by the degree of Cantonese exposure, particularly for learners in the early stage of acquisition. In addition to vowel quality differences, durational differences were proposed to explain the perceptual patterns. Furthermore, L2 English perception of the participants was found to modulate the perception of L3 Cantonese vowel length contrasts. Our findings demonstrate the bi-directional interaction between languages acquired at different stages, and provide concrete data to evaluate some speech acquisition models.

Purpose The purpose of this study was to examine the aging effects on the categorical perception (CP) of Mandarin lexical Tones 1–4 and Tones 1–2 in noise. It also investigated whether listeners' categorical tone perception in noise correlated with their general tone identification of 20 natural vowel-plus-tone signals in noise. Method Twelve younger and 12 older listeners with normal hearing were recruited in both tone identification and discrimination tasks in a CP paradigm where fundamental frequency contours of target stimuli varied systematically from the flat tone (Tone 1) to the rising/falling tones (Tones 2/4). Both tasks were conducted in quiet and noise with signal-to-noise ratios set at −5 and −10 dB, respectively, and general tone identification of natural speech signals was also tested in noise conditions. Results Compared with younger listeners, older listeners had shallower identification slopes and smaller discrimination peakedness in Tones 1–2/4 perception in all listening conditions, except for Tones 1–4 perception in quiet where no group differences were found. Meanwhile, noise affected Tones 1–2/4 perception: The signal-to-noise ratio condition at −10 dB brought shallower slope in Tones 1–2/4 identification and less peakedness in Tones 1–4 discrimination for both listener groups. Older listeners' CP in noise, the identification slopes in particular, positively correlated with their general tone identification in noise, but such correlations were partially missing for younger listeners. Conclusions Both aging and the presence of speech-shaped noise significantly reduced the CP of Mandarin Tones 1–2/4. Listeners' Mandarin tone recognition may be related to their CP of Mandarin tones.

Purpose The purpose of the study was to examine the aging effect on the categorical perception of Mandarin Chinese Tone 2 (rising F0 pitch contour) and Tone 3 (falling-then-rising F0 pitch contour) as well as on the thresholds of pitch contour discrimination. Method Three experiments of Mandarin tone perception were conducted for younger and older listeners with Mandarin Chinese as the native language. The first 2 experiments were in the categorical perception paradigm: tone identification and tone discrimination for a series of stimuli, the F0 contour of which systematically varied from Tone 2 to Tone 3. In the third experiment, the just-noticeable differences of pitch contour discrimination were measured for both groups. Results In the measures of categorical perception, older listeners showed significantly shallower slopes in the tone identification function and significantly smaller peakedness in the tone discrimination function compared with younger listeners. Moreover, the thresholds of pitch contour discrimination were significantly higher for older listeners than for younger listeners. Conclusion These results suggest that aging reduced the categoricality of Mandarin tone perception and worsened the psychoacoustic capacity to discriminate pitch contour changes, thereby possibly leading to older listeners' difficulty in identifying Tones 2 and 3.

Acoustic Study

This paper reports results of an acoustic study of stress in the Turkish dialect of the Northwest Caucasian language, Kabardian. Stressed syllables were found to have consistently higher fundamental frequency and characteristically greater duration and intensity than unstressed syllables. No evidence was found for secondary stresses. Schwa and, to a lesser extent, /ɐ/ were shown to undergo slight raising as their duration in unstressed syllables decreased. This gradient raising is likely due to coarticulatory overlap with adjacent consonants rather than a categorical shift in vowel quality. Considerations of articulatory effort rather than perceptual dispersion predict both the categorical alternation between stressed /aː/ and unstressed /ɐ/ in Kabardian and the non-categorical raising of schwa and /ɐ/ in unstressed syllables.

The purpose of the experiments reported on here was to attain an inventory of systematic intonational deviations observed in English utterances produced by native speakers of Dutch. In two production tests acoustic measurements are described of magnitude, slope, duration, direction and position of fundamental frequency contours, produced by native speakers of Dutch and of English on English utterances. In two perception tests the original capricious fundamental frequency contours (sentence melody) were replaced by experimentally controlled artificial contours, without greatly disturbing the remaining acoustic cues. In this way the perceptual relevance of the deviations could be tested by means of a subjective evaluation by native speakers of English. Finally two experiments are described which are of an exploratory character, in the latter of which use was made of spectrally rotated speech. The overall data of the experiments allow for the following conclusion: (a) British English listeners are able to judge the acceptability of resynthesized pitch contours in a very consistent manner. (b) Deviations which appear to be particularly relevant to the perception of non-nativeness are in order of perceptual importance: Magnitude of the pitch movement, WH-attribute (particular configuration often found on so-called WH-Questions), Direction of the pitch movement, Continuation (complex movement often found before a pause in a speech signal) and occasionally Inclination (slowly rising pitch from Mid to High level). (c) The perceptual relevance of some deviations appeared to be dependent on the linguistic structure of the utterance, viz. Overshoot (rise at end), Reset (virtual jump from Mid to High). The ultimate goal of our investigation is to come to an explicit inventory of perceptually relevant deviations. Suc an inventory would be helpful to establish an elementary set of rules concerning English intonation on behalf of Dutch learners of English.

Abstract A debate is underway regarding the perceptual and cognitive benefits of bilingualism and musical experience. This study contributes to the debate by investigating auditory inhibitory control in English-speaking monolingual musicians, non-musicians, tone language bilinguals, and non-tone language bilinguals. We predicted that musicians and tone language bilinguals would demonstrate enhanced processing relative to monolinguals and other bilinguals. Groups of monolinguals (N = 22), monolingual musicians (N = 19), non-tone language bilinguals (N = 20) and tone language bilinguals (N = 18) were compared on auditory Stroop tasks to assess domain-transferable processing benefits (e.g. auditory inhibitory control) resulting from potentially shared underlying cognitive mechanisms (Patel, 2003; Bialystok & DePape, 2009). In one task, participants heard the words “high” and “low” presented in high or low pitches, and responded regarding the pitch of the stimuli as quickly as possible. In another task, participants heard the words “rise” or “fall” presented in rising or falling pitch contours, and responded regarding the contour of the stimuli as quickly as possible. Results suggest transferable auditory inhibitory control benefits for musicians across pitch and contour processing, but any possible enhanced processing for speakers of tone languages may be task-dependent, as lexical tone activation may interfere with pitch contour processing.

The purpose of this investigation was to document acoustic characteristics of Pakistani English (PaKE) vowel sounds. The experiment was designed to examine the properties of ten vowels produced by Pakistani ESL learners. The analysis is based on the voice samples of recorded 50 CVC words. Total 5000 (10  10  50=5000) voiced samples were analyzed. The data consisted of 50 words of ten English vowel sounds [i: ɪ e ɔ: æ ə ɑ: u: ɒ ʊ]. Ten ESL speakers recorded their voice samples on Praat speech processing tool installed on laptop. Three parameters were considered i.e., fundamental frequency (F0), vowel quality (F1-F2) and duration. Formant patterns were judged manually by visual inspection on Praat Speech Processing Tool. Analysis of formant frequency shows numerous differences between male and female of F1 and F2, fundamental frequency and duration of English vowels. The voice samples provide evidence for higher and lower frequency of vowel sounds. Additionally, the data analysis illustrates that there were statistical differences in the values of short and long vowels coupled with vowel space plot showing explicit differences in locating the production of vowels of male & female vowel space acoustic realizations.
