This research investigated whether observing beat gesture and hearing contrastive accenting with novel words enhances their learning in early childhood and whether these effects differ by sex in light of sex differences in the pace of language development. Fifty-three 3- to 5-year-old boys and girls learned pairs of novel words with contrasting…

In this work, based on an oral corpus of semi-directed interviews conducted in French with 40 L1 Chinese speakers learning French in France and in English with 29 L1 Chinese speakers learning English in the United States, I investigated the quotative system in non-native speech of English and French as it is used in the Chinese diaspora in Paris…

To what extent can language acquisition be explained in terms of different associative learning mechanisms? It has been hypothesized that distributional regularities in spoken languages are strong enough to elicit statistical learning about dependencies among speech units. Distributional regularities could be a useful cue for word learning even…

This dissertation investigates the effect of phonetically cued emotional information (i.e., emotional prosody) on spoken word recognition. Even words whose meanings are not emotionally laden (e.g., "pineapple") can be uttered in a way that conveys anger, happiness, or sadness through phonetic modulation, and the current work investigates…

Infants in their first year manifest selective patterns of discrimination between languages and between accents of the same language. Prosodic differences are held to be important in whether languages can be discriminated, together with the infant's familiarity with one or both of the accents heard. However, the nature of the prosodic cues that…

The current study addresses an aspect of second language (L2) phonological acquisition that has received little attention to date--namely, the acquisition of allophonic variation as a word boundary cue. The role of subphonemic variation in the segmentation of speech by native speakers has been indisputably demonstrated; however, the acquisition of…

It has been widely shown that infants and adults are capable of using only prosodic information to discriminate between languages. However, it remains unclear which aspects of prosody, either rhythm or intonation, listeners attend to for language discrimination. Previous researchers have suggested that rhythm, the duration and timing of speech…

Speech utterances are more than the linear concatenation of individual phonemes or words. They are organized by prosodic structures comprising phonological units of different sizes (e.g., syllable, foot, word, and phrase) and the prominence relations among them. As the linguistic structure of spoken languages, prosody serves an important function…

Non-native speakers of English often experience problems in pronunciation as they are learning English, many such problems persisting even when the speaker has achieved a high degree of fluency. Research has shown that for a non-native speaker to sound most natural and intelligible in his or her second language, the speaker must acquire proper…
