“…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.

“…For the vowel intelligibility experiment, vowel sounds were presented in quiet and in SS noise at a 0-10 dB sensation level (SL) based on the detection thresholds measured before this study (Liu & Jin, 2011; see their Figure 3) with a step size of 2 dB for each listener. For example, given the detection threshold of the vowel /oe/ for the female EN speaker was 56.3 dB SPL, the sensation level of 2 dB indicated that the vowel /oe/ of the female EN speaker was presented at 58.3 dB SPL (56.3+2 dB SPL).…”

“…Vowels were presented in quiet as well as in SS noise with sensation levels from 0 to 10 dB based on the individual listener's vowel detection thresholds for each vowel. These detection thresholds were measured by Liu and Jin (2011). The selection of the sensation levels instead of the SNRs was to equalize the audibility across all the twelve vowels.…”

Intelligibility of American English vowels of native and non-native speakers in quiet and speech-shaped noise.This study examined intelligibility of twelve American English vowels produced by English, Chinese, and Korean native speakers in quiet and speech-shaped noise in which vowels were presented at six sensation levels from 0 dB to 10 dB. The slopes of vowel intelligibility functions and the processing time for listeners to identify vowels were dependent on speakers' language backgrounds and non-native speakers' vowel intelligibility in quiet. These results indicated that noise background affected non-native speakers' vowel intelligibility more greatly than native speakers, possibly due to the acoustic deviations in non-native speech and lack of listeners' experience to non-native produced speech.

“…detection thresholds of native and non-native speech sounds for a given population like Mandarin Chinese-native listeners. Because vowel detection thresholds were primarily determined by the vowel spectrum (Liu and Eddins, 2008;Liu and Jin, 2011), different detection thresholds across stimuli may be derived from the spectral difference. Thus, to rule out the effect of spectral difference, detection thresholds of stimuli with the same spectrum of harmonic signals, but with noise carriers, were examined.…”

Detection thresholds of Chinese vowels, Korean vowels, and a complex tone, with harmonic and noise carriers were measured in noise for Mandarin Chinese-native listeners. The harmonic index was calculated as the difference between detection thresholds of the stimuli with harmonic carriers and those with noise carriers. The harmonic index for Chinese vowels was significantly greater than that for Korean vowels and the complex tone. Moreover, native speech sounds were rated significantly more native-like than non-native speech and non-speech sounds. The results indicate that native speech has an advantage over other sounds in simple auditory tasks like sound detection.
