Boiling down prosody for the classification of boundaries and accents in German and English
نویسندگان
چکیده
In the focus of this paper is a comparison of the most relevant prosodic features/feature classes for the classification of boundaries and accents in German and in English. Principal components were computed based on a large prosodic feature vector; these principal components were used as predictor variables in a Linear Discriminant analysis as well as in a Classification and Regression Tree. The number of the most relevant principal components was between three and five; for both languages and for boundary and accent classification alike, most important were principal components modelling duration, in combination with energy, followed by pauses and F0.

The Prosody Module
We describe the acoustic-prosodic and syntactic-prosodic annotation and classification of boundaries, accents and sentence mood integrated in the Verbmobil system for the three languages German, English, and Japanese. For the acoustic-prosodic classification, a large feature vector with normalized prosodic features is used. For the three languages, a multilingual prosody module was developed th...
متن کاملSemantic Prosody: Its Knowledge and Appropriate Selection of Equivalents
In translation, choosing appropriate equivalent is essential to convey the right message from source-text to target-text, and one of the issues that may have a determinative role in appropriate equivalent choice is the semantic prosody (SP) behavior of words and the relation existing between the SP of a word and semantic senses (i.e. negativity, positivity or neutrality) of its collocations in ...

متن کاملIncremental Prosody Modelling for Interaction Management in Spoken Dialogue Systems
Prosody, as manifested in accents and phrasal boundaries, is a recognized and important aspect of human language understanding. Accents are supported by syllables, whereas phrasal boundaries occur between words. The influence of both accents and boundaries on the other hand, extends to surrounding syllables and, in the case of boundaries, preceding words (even as far back as the last accent in ...
متن کاملAnalysis of emotion in speech using perceived and automatically extracted prosodic features
This study investigates the relationship between emotional states and prosody. A prosody detection algorithm was applied to emotional speech to extract accents and intonational boundaries automatically and these were compared with hand-labeled prosodic units. The measurements used in the detection algorithm are derived from duration, pitch, harmonic structure, spectral tilt, and amplitude. The ...
