Native clear speech aids speech perception for various native populations such as hearing-impaired adults (Picheny et al., 1985). Compared to native speech, little is known about the benefit of non-native clear speech (Smijlanic and Bradlow, 2011). The current study investigates whether non-native clear speech can aid both native and non-native lis...

While access to authentic input from native speakers is critical when learning to produce speech in another language (Flege et al., 1997; Flege etal., 1995; MacKay et al., 2001; inter alia), this option is not always accessible to all learners. With that in mind, this study explores how another type of naturalistic exposure, foreign film, can contr...

It is well established that some individual factors (i.e., age, amount of input, motivation, etc.) play a considerable role in second language (L2) speech perceptual learning (Akahane-Yamada, 1995; Flege et al., 1997; Flege & Liu, 2001; inter alia). However, other factors, like personality type, have received less attention. This study therefore in...

Reduction of unstressed vowels is a well-known aspect of English phonology that is not present in Spanish, and the absence of such reduction contributes to accentedness in English for L1 Spanish speakers (Flege & Bohn, 1989). Previous studies have established that stress, coarticulatory effects of the previous consonant, and sociolinguistic factors...

Voice Onset Time (VOT) and onset f0 are known correlates of voicing distinctions in stops and both contribute to the production and perception of voicing (House & Fairbanks, 1953; Abramson & Lisker, 1965). The values of VOT and onset f0 which correspond to voicing categories vary cross-linguistically. Second language (L2) learner often have to acqu...

Recent research demonstrates that second language learning can affect first language speech production. This has been shown for proficient long-term second language learners in immigration settings (Flege, 1987) as well as novice learners in the study abroad setting (Chang, 2013). The question addressed in the present study is whether learners acqu...

In spoken language, gestural overlap in speech production regularly leads to coarticulation between neighboring segments, resulting in assimilation measurable by changes in the acoustic parameters. Vowels in adjacent syllables can coarticulate in a phenomenon called vowel-to-vowel coarticulation, which is subject to variation based on environmental...

Second language learning has been shown to affect first language production (Flege, 1987; Major, 1992; Sancier & Fowler, 1997, inter alia). Less is known about whether and how experience with another language may affect first language perception. The present study examines the use of preceding vowel duration vs. voicing during closure as cues to wo...

Speech has been shown to accommodate the communicative needs of listeners, for example, for increased intelligibility compared to normal speech. Previous research shows that native speakers adapt their speech in the presence of noise (Garnier et al., 2006), and when addressing children (Biersack et al., 2005) or foreigners (Scarborough et al., 2007...

English is typically described as a language in which voicing contrast is not neutralized in word-final position. However, a tendency towards devoicing (at least partial) of final voiced obstruents in English has been reported by the previous studies (e.g., Docherty (1992) and references therein). In the present study, we examine a number of acoust...

An experimental investigation of Russian geminates revealed that intervocalic, post-stress, and word-initial geminates have an earlier perceptual boundary in relation to the average singleton duration in these positions. This provides an articulatory and perceptual advantage for geminate production and discrimination, which may explain cross-lingui...

Project
This project is an acoustic investigation of vowel-to-vowel coarticulation in three languages, with the goal of understanding the synchronic relationship between vowel harmony and vowel-to-vowel coarticulation. Studies in Spanish, Tatar, and Hungarian contrast coarticulation in languages with and without vowel harmony in target words under differing conditions of stress.
Project
In this project I design and develop machine learning algorithms for automatically measuring, with high precision, phonetic properties of speech at the level of human inter-transcriber reliability. The methods rely on several advances over existing computational systems: novel representations of the speech signal and new structured prediction and deep learning algorithms. These automatic methods allow for low-cost replication of phonetic studies (increasing the rigor of studies of speech) and expand the range of empirical and theoretical issues we can address.
