Generation and perception in conversational speech with adv
نویسنده
چکیده
Aiming at natural F0 control for conversational speech synthesis, F0 characteristics are analyzed from both generation and perception viewpoints. By systematically designing conversational situations and utterances with adverb phrases expressing different degree of markedness, their F0 characteristics are compared. The comparison shows the consistent F0 control dependencies not only on adverbs themselves but also on the attribute of neighboring adjective phrases. Strong positive/negative correlation is observed between the markedness of adverbs and F0 height when an adjective phrase with a positive/negative image is followed to the current adverb phrase. These consistencies have been perceptually confirmed by naturalness evaluation tests using the same two-phrase samples with different F0 heights. These results indicate the possibility of F0 control for natural conversational speech using lexical markdness information and adjacent word attributes.

Ethnomethodology and Conversational Analysis
In a speech community, people utilize their communicative competence which they have acquired from their society as part of their distinctive sociolinguistic identity. They negotiate and share meanings, because they have commonsense knowledge about the world, and have universal practical reasoning. Their commonsense knowledge is embodied in their language. Thus, not only does social life depend...
متن کاملOn the Evaluation of the Conversational Speech Quality in Telecommunications
We propose an objective method to assess speech quality in the conversational context by taking into account the talking and listening speech qualities and the impact of delay. This approach is applied to the results of four subjective tests on the effects of echo, delay, packet loss, and noise. The dataset is divided into training and validation sets. For the training set, a multiple linear re...
متن کاملCorrelation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
متن کاملReliability of Interaural Time Difference-Based Localization Training in Elderly Individuals with Speech-in-Noise Perception Disorder
Background: Previous studies have shown that interaural-time-difference (ITD) training can improve localization ability. Surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (ITD ENV). We sought to investigate the reliability of an ITD ENV-based training program in speech-in-noise perception a...
متن کاملTemporal properties in clear speech perception.
Three experiments were conducted to study relative contributions of speaking rate, temporal envelope, and temporal fine structure to clear speech perception. Experiment I used uniform time scaling to match the speaking rate between clear and conversational speech. Experiment II decreased the speaking rate in conversational speech without processing artifacts by increasing silent gaps between ph...
