“…Liu and Jin 9 showed that English vowels spoken by CN and KN speakers had greater variability of F0 contours and higher VISC distances compared to those spoken by EN speakers. Jin et al 10 also found individual vowel categories spoken by KN speakers were more overlapped with each other on a vowel space than those spoken by EN and CN speakers.…”

“…7,8 Our recent study suggested that greater temporal dynamics in English vowels (more variability of F0 contours and formant movements) for non-native speakers might result in their lower intelligibility in quiet and noisy conditions than their native peers. 9 However, because this previous study measured the VISC of very few numbers of speakers (e.g., four in each non-native group), their finding was hard to generalize. Thus a main purpose of the current study was to investigate whether there are differences in the VISC of English vowels produced by native and non-native speakers and whether such a) Author to whom correspondence should be addressed.…”

The current study examined Vowel Inherent Spectral Change (VISC) of English vowels spoken by English-, Chinese-, and Korean-native speakers. Two metrics, spectral distance (amount of spectral shift) and spectral angle (direction of spectral shift) of formant movement from the onset to the offset, were measured for 12 English monophthongs produced in a /hvd/ context. While Chinese speakers showed significantly greater spectral distances of vowels than English and Korean speakers, there was no significant speakers' native language effect on spectral angles. Comparisons to their native vowels for Chinese and Korean speakers suggest that VISC might be affected by language-specific phonological structure.

“…The sampling rate of 24,414 Hz was used to be compatible with the hardware of sound processing. The monaural processing was used to be consistent with previous work in our laboratories and to facilitate comparisons with previous findings (Liu & Jin, 2011, 2013; Liu et al, 2012; Mi et al, 2013; Jin & Liu, 2014). Stimulus presentation was controlled by a Tucker-Davis Technologies mobile processor (RM1).…”

The identification of English consonants in quiet and multi-talker babble was examined for three groups of young adult listeners: Chinese in China, Chinese in the USA (CNU), and English-native listeners. As expected, native listeners outperformed non-native listeners. The two non-native groups had similar performance in quiet, whereas CNU listeners performed significantly better than Chinese in China listeners in babble. It is concluded that CNU listeners may benefit from English experience, for example, better use of temporal variation in noise and better capacity against informational masking, to perceive English consonants better in babble. Possible explanations regarding the differential noise effect on the three groups are discussed.

Purpose The goal of this study was to investigate vowel detection and identification in noise and provide baseline data regarding how vowel perception changed with signal-to-noise ratios. Psychometric functions of vowel detection and identification for 12 American English isolated vowels in long-term speech-shaped noise were examined for young listeners with normal hearing in this study. Method Vowel detection was measured at sensation levels from −10 to +5 dB (re: thresholds of vowel detection from the study of Liu and Eddins, 2008a ) with a 4-interval forced-choice procedure. Thresholds of vowel detection were computed for each listener as the speech level at which 70.7% correct performance was reached. Vowel identification was then examined at sensation levels from 0 to 12 dB relative to detection thresholds for each listener. Thresholds of vowel identification were calculated as the speech level with vowel identifiability ( d ′) equals to 1. Results Thresholds of vowel detection and identification were significantly affected by vowel category. Slopes of psychometric functions of vowel identification were significantly dependent on vowel category, whereas slopes of psychometric functions of vowel detection were not. Conclusions These results suggest that, given the same sensation levels, especially at low sensation levels, vowel sounds are not equally perceivable in terms of identifiability.
