An Investigation of the Phonetic Variation of the Word-Initial /l/ and /n/ Across Regional Varieties of Mandarin
This study investigates how word-initial /l/ and /n/ are phonetically realized in Mandarin Chinese as produced by speakers from three regions: Beijing (close to Standard Mandarin), Changsha (where Xiang, which contains /l/ but not /n/, is also spoken locally), and Meizhou (where Hakka, which contains both /l/ and /n/, is also spoken locally), focusing on acoustic cue use and phonological context effects. Using acoustic analysis and random forest …
Perceptual asymmetries in the development of lexical tone perception in Thai-learning children
Discrimination of vowel and consonant pairs is influenced by their order, known as perceptual asymmetry, and recent research suggests a similar effect for lexical tones. This study tested whether discrimination of two consecutive tones is easier when a dynamic contour tone (e.g., rising/falling) precedes a static-level tone (e.g., low/high) than vice versa. Thai-speaking children aged 4, 6, and 8 years and adults completed an AX task with four to…
Historical Models and Theories of Speech Learning
Speech is the most effective means to communicate thoughts, ideas, and experiences. Unlike native language (L1) learners, adult speakers of a second language (L2) rarely produce consonants, vowels, or suprasegmental features of the target language without a detectable foreign accent. The causes of this ubiquitous and complex phenomenon have been a subject of theoretical debate and empirical research for many decades, resulting in several theoreti…

The Effect of Pitch Accent on the Perception of English Lexical Stress
The relative weighting of f0 and vowel reduction in English spoken word recognition at the sentence level were investigated in one two-alternative forced-choice word identification experiment. In the experiment, an H* pitch-accented or a deaccented word fragment (e.g., AR- in the word archive) was presented at the end of a carrier sentence for identification. The results of the experiment revealed differences in the cue weighting of English lexic…
Disentangling Effects of Memory Storage and Inter-articulator Coordination on Generalization in Speech Motor Sequence Learning
Quantitative Acoustic versus Deep Learning Metrics of Lenition
Spanish voiced stops /b, d, ɡ/ surfaced as fricatives [β, ð, ɣ] in intervocalic position due to a phonological process known as spirantization or, more broadly, lenition. However, conditioned by various factors such as stress, place of articulation, flanking vowel quality, and speaking rate, phonetic studies reveal a great deal of variation and gradience of these surface forms, ranging from fricative-like to approximant-like [β⊤, ð⊤, ɣ⊤]. Several…
Second Language Speech Learning
Including contributions from a team of world-renowned international scholars, this volume is a state-of-the-art survey of second language speech research, showcasing new empirical studies alongside critical reviews of existing influential speech learning models. It presents a revised version of Flege's Speech Learning Model (SLM-r) for the first time, an update on a cornerstone of second language research. Chapters are grouped into five thematic …
English Focus Perception by Mandarin Listeners
This study compared how well native Mandarin and native English speakers can perceive prosodically marked focus in English echo questions. Twenty-five yes-no echo questions were produced with a sentence focus, a verb focus, and an object focus. After hearing each sentence, they were asked to choose a correct response. Native English listeners were more accurate than native Mandarin on verb and object focus, but not on sentence focus. More importa…
Suprasegmentals
Voice pitch is used to change word meaning in the majority of the world's languages.
Speech Perception Among School-Aged Skilled and Less Skilled Readers
Effects of musical experience and training on pitch contour perception
Effects of two training procedures in cross-language perception of tones
Native Thai Speakers’ Acquisition of English Word Stress Patterns
Training English and Chinese Listeners to Perceive Thai Tones
The ability of native English (NE) and native Chinese (NC) speakers to identify and discriminate the mid- versus the low-tone contrast in Thai was investigated before and after auditory training. The variables under investigation were first language background and the interstimulus interval (ISI) of the presentation (500 ms vs. 1500 ms). The NC group outperformed the NE group in its ability to discriminate the two Thai tones under the ISI 500 ms …
Factors Affecting Stress Placement for English Nonwords include Syllabic Structure, Lexical Class, and Stress Patterns of Phonologically Similar Words
Seventeen native English speakers participated in an investigation of language users' knowledge of English main stress patterns. First, they produced 40 twosyllable nonwords of varying syllabic structure as nouns and verbs. Second, they indicated their preference for first or second syllable stress of the same words in a perception task. Finally, they indicated words they considered to be phonologically similar to the nonwords. Analyses of varian…

Acoustic characteristics of English fricatives
This study constitutes a large-scale comparative analysis of acoustic cues for classification of place of articulation in fricatives. To date, no single metric has been found to classify fricative place of articulation with a high degree of accuracy. This study presents spectral, amplitudinal, and temporal measurements that involve both static properties (spectral peak location, spectral moments, noise duration, normalized amplitude, and F2 onset…
Non-native Production of Thai
This paper reports a study of the production of Thai vowels, consonants, and tones by native English speakers using two forms of evaluation acoustic measurements and auditory evaluation by native Thai-speaking listeners The investigation focused on (a) the acoustic parameters along which the two groups of speakers differ, and (b) which of these acoustic parameters influenced native listeners' judgments of perceived degree of accentedness Three na…
