This paper examines how ordinary listeners, naïve with respect to the phonetics and phonology of prosody, perceive the location of prosodic boundaries that demarcate speech " chunks " and prominences that serve a " highlighting " function, in spontaneous speech (Buckeye corpus). Over 70 naïve listeners marked the locations of prominences and boundaries in a(More)
Speakers communicate pragmatic and discourse meaning through the prosodic form assigned to an utterance, and listeners must attend to the acoustic cues to prosodic form to fully recover the speaker's intended meaning. While much of the research on prosody examines supra-segmental cues such as F0 and temporal patterns, prosody is also known to affect the(More)
0. Introduction This study examines the acoustic correlates of prosodic prominence as perceived by a large number of native listeners of American English who are naïve to the phonetics and phonology of prosody. In English, as in other stress languages, speech utterances are chunked into smaller prosodic phrases and within a prosodic phrase some words are(More)
I investigate the acoustic correlates of prosodic prominence and boundary, as they are perceived by naïve listeners, in spontaneous speech from American English (Buckeye corpus). Prosodic prominence and phrasing serve different functions in speech communication: prosodic phrase boundaries demarcate speech chunks that typically cohere semantically, while(More)
This study investigated the relation between various acoustic features and prominence. Past research has suggested that duration , pitch, and intensity all play a role in the perception of prominence. In our past work, we found a correlation between these acoustic features and speaker agreement over the placement of prominence. The current study was(More)
Complex disfluencies that involve the repetition or correction of words are frequent in conversational speech, with repetition disfluencies alone accounting for over 20% of disfluencies. These disfluencies generally do not lead to comprehension errors for human listeners. We propose that the frequent occurrence of parallel prosodic features in the(More)
As an effort to make prosody useful in spontaneous speech recognition, we adopt a quasi-continuous prosodic annotation and accordingly design a prosody-dependent acoustic model to improve ASR performances. We propose a variable-parameter Hidden Markov Models, modeling the mean vector as a function of the prosody variable through a polynomial regression(More)
Repetition disfluencies are among the most frequent type of disfluency in conversational speech, accounting for over 20% of disfluencies, yet they do not generally lead to comprehension errors for human listeners. We propose that parallel prosodic features in the REP and ALT intervals of the repetition disfluency provide strong perceptual cues that signal(More)
