Pause Duration and Variabil
نویسنده
چکیده
Generating natural sounding synthetic speech from text requires a division of a text into IPs and assigning pauses between those phrases. A difficulty which faces attempts to model pauses quantitatively is high degree of variability exhibited by speakers in pause placement and duration. The present study seeks to investigate if Synchronous Speech (speech elicited when two speakers are asked to read a text together) can be used as a mean to reduce inter-speaker variability providing more reliable data for accurate modeling pause durations at IP breaks. We find reduced variability in pause duration when speakers read a text in synchrony. We also find an apparent dependence of pause duration on the length and/or syntactic complexity of the preceding phrase. The reduction in variability when reading synchronously is most evident for the one pause exhibiting markedly longer mean duration.

The effect of surrounding phrase lengths on pause duration
Little is known about the determining influences on the length of silent intervals at IP boundaries and no current models accurately predict their duration. The contribution of independent factors with different characteristic properties to pause duration needs to be explored. The present study seeks to investigate if pause duration is correlated with the length of sentences or phrases precedin...
متن کاملThe Role of Pause Occurrence and Pause Duration in the Signaling of Narrative Structure
This paper addresses the prosodic feature of pause and its distribution in spontaneous narrative in relation to the role it plays in signaling narrative structure. Pause duration and pause occurrence were taken as variables for the present analysis. The results indicate that both variables consistently mark narrative section boundaries, suggesting thus that pause is a very important structuring...
متن کاملDependency analysis of read Japanese sentences using pause and F0 information: a speaker independent case
This paper deals with the problem of exploiting prosodic information in syntactic analysis of sentences. Duration of pauses at phrase boundaries and relative F0 contour features have been found to be effective for parsing in speaker-dependent case. In this paper, effectiveness of pause and F0 information was examined in a speakerindependent manner by using prosodic features extracted from the s...
متن کاملDurational patterning at syntactic and discourse boundaries in Mandarin spontaneous speech.
This study focused on durational cues (i.e., syllable duration, pause duration, and syllable onset intervals (SOIs)) at discourse boundaries in two dialects of Mandarin,Taiwan and Mainland varieties. Speech was elicited by having 18 participants describe events in The Pear Story film. Recorded data were transcribed, labeled, and segmented into clauses. Discourse boundary indices were used to la...
متن کاملRole of adenosine on ventricular overdrive suppression in isolated guinea pig hearts and Purkinje fibers.
The present study was undertaken to demonstrate and characterize potentiation of ventricular overdrive suppression by adenosine. To substantiate that adenosine has an enhanced effect on overdrive suppression, it would be necessary to demonstrate that adenosine increases pause duration independent of slowing spontaneous pre-drive rate. In isolated perfused guinea pig hearts with surgically induc...
