Prosodic Structure Representation for Boundary Detection in Spontaneous French
نویسندگان
چکیده
Automatic speech processing has recently turned to the treatment of continuous spontaneous speech, which demands, among many other issues, a representation of its prosodic organization. This paper presents a new approach to automatic prosodic boundary detection and prosodic unit structuring, based, with certain changes, on a descriptive theory of the French prosodic system initially proposed for prepared speech. This theory had been transformed into a set of rules so as to create a hierarchical representation of a phrase in spontaneous French in the form of a prosodic tree. The method had been manually verified and then applied to a spontaneous speech database in order to obtain a statistical description of prosodic structures.

Prosodic Trees for Boundary Detection in ASR in French
Prosodic trees as a hierarchical representation of prosodic organization in French proved to be efficient for automatic processing of continuous speech. We applied this technique to the prosodic boundary detection on the output of a speech recognition application in order to test whether prosodic boundaries of different levels in tree confirm or not recognition hypotheses. Two types of tree con...
متن کاملAn evaluation of machine learning methods for prominence detection in French
The automatic detection of prosodically prominent syllables is crucial for analysing speech, especially in French where prominence contributes substantially to prosodic grouping and boundary demarcation. In this paper, we compare different machine learning techniques for the automatic detection of prominent syllables, using prosodic features (including pitch, energy, duration and spectral balan...

________________________________________________________________________________________________________ The prosodic structure of French involves a tight connection between the location of prominent syllables and locations where the flow of speech is divided into prosodic units. Researchers agree that the final (full) syllable of the smallest prosodic unit is prominent. The possibility remains...
متن کاملHow far can prosodic cues help in word segmentation?
Prosodic cues are of great importance in parsing speech signal into prosodic and lexical units. Listeners detect the changes of the prosodic parameters and interpret them to detect sentence modalities or the mood of the speaker. Some automatic speech recognition systems try to use prosodic parameters to detect boundaries of prosodic units and help thus the acoustic decoding process. Although th...
متن کاملUnsupervised Extraction of Prosodic Structure
Our approach for unsupervised extraction of prosodic structure in spontaneous speech consists of the four steps: chunking into interpausal units, syllable nucleus extraction, prosodic boundary detection, and pitch accent detection. The extraction is based on acoustic features derived from F0 parameterization, and on energy and segment duration features. Phrase boundaries and accents are detecte...
