One of the first challenges facing the young language learner is the task of segmenting words from a natural language speech stream, without prior knowledge of how these words sound. Studies with younger children find that children find it easier to segment words from fluent speech when the words are presented in infant-directed speech, i.e., the…

Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

A growing literature has demonstrated that prosodic sensitivity is related to early literacy development; however, the precise nature of this relationship remains unclear. It has been speculated in recent theoretical models that the observed relationship between prosodic sensitivity and early literacy might be partially mediated by children's…

Discusses a word-onset gating technique to investigate the role of prosody in word recognition. Subjects were asked to identify words based on onsets followed by information about full word prosody. Results showed that words were correctly recognized with significantly less segmental onset information when word prosody was available. (Author/VWL)

Two experiments sought to extend the demonstration of English-learning infants' abilities to segment nouns from fluent speech to a new lexical class: verbs. Moreover, we explored whether two factors previously shown to influence noun segmentation, stress pattern (strong-weak or weak-strong) and type of initial phoneme (consonant or vowel), also…

This analysis describes the phonology and grammar of the contact vernacular referred to as Roper Creole, spoken at Ngukurr on the Roper River. The analysis deals primarily with the creole used between native Roper Creole speakers. The phonology is similar to that of the Aboriginal languages of the area, with the addition of a few English sounds.…
