Deviation of real speech from grammatical ideals due to disfluency and other speech errors presents potentially serious problems for the language learner. While infants may initially benefit from attending primarily or solely to infant-directed speech, which contains few grammatical errors, older infants may listen more to adult-directed speech. In a first experiment, Post-verbal infants preferred fluent speech to disfluent speech, while Pre-verbal infants showed no preference. In a second…

Speech Disfluencies: Their Role in Comprehension and Word Learning
One of the most extraordinary aspects of human development is how children acquire their language(s) by listening to spontaneous speech. Perhaps more remarkably, they do so even though speech is…
Disfluencies in German adult- and infant-directed speech
We investigate the occurrence of disfluencies (lengthening, filled pauses, silent pauses, abandoned utterances, and repairs) in German infant-directed speech (IDS), as compared to German…

Phonetic category cues in adult-directed speech: Evidence from three languages with distinct vowel characteristics
Using an artificial language learning manipulation, Maye, Werker, and Gerken (2002) demonstrated that infants’ speech sound categories change as a function of the distributional properties of the…
I Forget What That's Called! Children's Online Processing of Disfluencies Depends on Speaker Knowledge.
TLDR
The results of this experiment suggest that, like adults, children modify their expectations about the informativeness of disfluencies on a speaker-specific basis.
Toddlers use speech disfluencies to predict speakers' referential intentions.
TLDR
The results reveal that young children reliably attend to speech disfluency early in lexical development and are able to use disfluencies in online comprehension to infer speaker intention in advance of object labeling.
The acoustic salience of prosody trumps infants' acquired knowledge of language-specific prosodic patterns.
Development in children's comprehension of linguistic register.
For socially appropriate communication, speakers must command a variety of linguistic styles, or registers, that vary according to social context and social relationships. This study examined…

Disfluency in speech input to infants? the interaction of mother and child to create error-free speech input for language acquisition
TLDR
The results suggest that younger and older infants attend differently to infant and adult- directed speech, and that older infants may be able to differentiate grammatical adult-directed input from input distorted by disfluency.
Infant-Directed Speech Facilitates Word Segmentation.
TLDR
The experiments reported here suggest that infant-directed speech facilitates word segmentation and may be useful for other aspects of language acquisition as well.
Acoustical cues and grammatical units in speech to two preverbal infants*
TLDR
Examining the syntactic and prosodic characteristics of the maternal speech to two infants between six and ten months finds infant-directed speech to be characterized by generally short utterances, isolated words and phrases, and large numbers of questions, but longer utterances are also found.

When Can Listeners Detect Disfluency in Spontaneous Speech?
TLDR
Though more common around disfluencies than at similar points in controls, failures of word identification were not reliably associated with detection and were discussed in the light of computational models of disfluency detection.

Effects of backward speech and speaker variability in language discrimination by rats.
TLDR
The extent to which rats can generalize prosodic cues that have been extracted from a training corpus to new sentences is explored and how this discrimination process is affected by the normalization of the sentences when multiple speakers are introduced is explored.

TLDR
Three experiments investigated the role of prosodic structure for infants' recognition of embedded word sequences and found that the advantage of the well-formed unit is at least partially due to infants' use of prosody to parse continuous speech.
