We examine the ability of supervised text classification models to identify several discourse properties from teachers' speech with an eye for providing teachers with meaningful automated feedback about the quality of their classroom discourse. We collected audio recordings from 28 teachers from 10 schools in 164 authentic classroom sessions,…

Augments Michael Studdert-Kennedy's state-of-the-art report on speech perception research (EJ 227 656) with comments on categorical perception of speech and nonspeech stimuli, speech perception in context, the role of prosody, and development/impairments of speech perception. Includes a summary of a discussion on speech perception research. (RL)

The practice of playing taped spoken French just before the beginning of a regular foreign language class rests on the premise that regular exposure to unedited foreign speech sensitizes one to its unique intonation, rhythm, and sounds. It is hypothesized that the ability to identify a language may be the first step in listening. A review of…

A series of experiments investigated infants' perception of inherent structural organization in the prosody of utterances. The experiments used a listening preference procedure to test: perceptions of appropriate pauses in child-directed and adult-directed speech; perceptions of appropriate pauses in speech filtered for most segmental features but…

Reviews research on prosody and segmental perception, segmentation and invariance, categorical perception of speech and nonspeech, feature detectors, scaling speech sounds to an auditory-articulatory space, acoustic-phonetic dependencies within the syllable, higher order (nonphonetic) factors in the comprehension of fluent speech, and cerebral…

Punctuation serves as a system of visual markers that contradict previously generated false grammatical expectations. Word order conditions define the redundant or critical aspect of punctuation cues to visual display. Parsing (grouping) sentences into meaningful phrases and clauses aids language comprehension, and children who have reading…
