In this study we show that the perception of lateral variants by Puerto Rican listeners changes according to who the listener believes is speaking. Puerto Rican listeners heard sentences with target words featuring either rhotic [voiced alveolar tap or flap] or lateral [l] (amo[voiced alveolar tap or flap] -- amo[l]) codas, a sociophonetic…

The practice of second language (L2) speech perception has traditionally relied on equal-interval perceptual scales and novice listeners' (NLs) impressionistic judgments of constructs such as accentedness and comprehensibility (Munro & Derwing, 2011). However, issues have surfaced with respect to how well NLs can use these scales, whether they…

Factors that affect comprehension of accented English (e.g., Harding, 2011) have been well studied, but little research examines how listeners' proficiency affects their sensitivity to second language (L2) accent. The current study investigated the effect of test takers' English proficiency on their comprehension ratings and ability to correctly…

The purpose of this case study is twofold: it (1) explores multilingual raters' judgements regarding the accentedness and comprehensibility of second language speech and (2) examines how the raters' language backgrounds influence their judgements. In this study, six multilingual Singaporean raters judged the accentedness and comprehensibility of…

Purpose: Previous studies reported that children acquire Cantonese tones before 3 years of age, supporting the assumption in models of phonological development that suprasegmental features are acquired rapidly and early in children. Yet, recent research found a large disparity in the age of Cantonese tone acquisition. This study investigated…

This study explores the most perceivable phonological features of Hong Kong (HK) L2 English speakers and how they affect the perception of HK L2 English speech from the perspective of both native and non-native English listeners. Conversational interviews were conducted to collect speech data from 20 HK speakers of English and 10 native speakers…

A fundamental issue in speech science concerns the extent to which speech sounds are mentally represented by articulatory-motor and/or auditory-acoustic features. This dissertation aims to expand upon the current literature by investigating changes in production and perception following visual feedback training with either articulatory or acoustic…

The speech of second language learners is often influenced by phonetic patterns of their first language. This can make them difficult to understand, but sometimes for listeners of the same first language to a lesser extent than for native listeners. The present study investigates listeners' awareness of the accent by asking whether accented speech…

Where native speakers supposedly are fluent by default, nonnative speakers often have to strive hard to achieve a nativelike fluency level. However, disfluencies (such as pauses, fillers, repairs, etc.) occur in both native and nonnative speech and it is as yet unclear how fluency raters weigh the fluency characteristics of native and nonnative…

Research in second language speech has often focused on listeners' accent judgment and factors that affect their perception. However, the topic of listeners' application of specific sound categories in their own perceptual judgments has not been widely investigated. The current study explored how listeners from diverse language backgrounds weighed…

Previous research has argued that fundamental frequency is a critical component of phonetic accommodation. We tested this hypothesis in an auditory naming task with two conditions. Participants in an Unfiltered Condition completed an auditory naming task with a single male model talker. A second group of participants was assigned to a Filtered…
