Prediction of F0 height of filled pauses in spontaneous Japanese: a preliminary report
نویسنده
چکیده
F0 values of filled pauses (FP) in the Corpus of Spontaneous Japanese were analyzed to examine the mechanism by which the F0 heights of FP were determined. Statistical analyses of the F0 values of FP occurring in between two full-fledged accentual phrases (AP) revealed correspondence between the occurrence timing of FP and the F0 height. Based upon this finding, 5 models of F0 prediction were proposed. Comparison of the mean prediction errors revealed that the best prediction was obtained in a model that linearly interpolate the phrase-final L% tone of the immediately preceding AP and the phrase-initial %L tone of the immediately following AP. This finding suggests that the F0 of FP was specified at the level of phonetic realization rather than phonological prosodic representation.

Acoustico-phonetic characteristics of filled pauses in spontaneous French speech: preliminary results
In the current analysis we examined the acoustic and phonetic characteristics of filled pauses in spontaneous French speech and their relationship to the prosody of the surrounding context. Two main results emerged : 1) There was no effect of the duration of filled pauses or their sentence location on their F0 patterns or on the differences between the highest and lowest values. 2) There was no...
متن کاملVoice-Quality Difference Between the Vowels in Filled Pauses and Ordinary Lexical Items
Acoustic differences between the vowels in filled pauses and ordinary lexical items such as nouns and verbs were examined to know if there was systematic difference of voice-quality. Statistical test of material taken from the Corpus of Spontaneous Japanese showed that, in most cases, there was significant difference of acoustic features like F0, F1, F2, intensity, jitter, shimmer, TL, H1-H2, H...
متن کاملDependency Analysis of Spontaneous Monologue Speech Using Pause and F0 Information: A Preliminary Study
This paper deals with the problem of exploiting prosodic information in syntactic analysis of spontaneous monologue utterances of non-professional speakers. Duration of pauses at phrase boundaries and relative F0 contour features, which improve parsing accuracy of read sentences, were also found to be effective for parsing spontaneous speech. Dependency analysis was performed by the minimum pen...
متن کاملA Real-time System Detecting Filled Pauses in Spontaneous Speech
This paper describes a method for detecting filled pauses (including word lengthening), which are one of the hesitation phenomena. This detection is important in speech dialogue systems because they play valuable roles in oral communication. Although there have been a few previous speech recognition systems handling filled pauses, they have not detected them individually and consequently could ...
متن کاملDetecting Filled Pauses in Tutorial Dialogs
As dialog systems become more capable, users tend to talk more spontaneously and less formally. Spontaneous speech includes features which convey information about the user’s state. In particular, filled pauses, such as um and uh, can indicate that the user is having trouble, wants more time, wants to hold the floor, or is uncertain. In this paper we present a first study of the acoustic charac...
