چکیده

In this study we compare the ESTER corpus of journalistic speech [1] and the NCCF corpus of spontaneous speech [2] in terms of duration, f0 and spectral reduction in productions automatically detected as speech units between pauses. Continuation f0 rises are overall absent in spontaneous speech and speech units reveal a declination slope with less amplitude than in journalistic speech. For both corpora, lengthening starts around 60% of the sequence duration, but significantly less in spontaneous speech. Lengthening in the initial part of the sequence is observed in journalistic speech only. As expected we measure a faster speech rate in spontaneous speech with shorter vowel durations implying partly only a more important vowel reduction.

Prosodic hierarchy and spectral realization of vowels in French

The aim of this study is to relate spectral realization of vowels and prosodic hierarchy in continuous speech. The IRISA speech alignment system is used and formant values of oral vowels are automatically measured in a total of 500,000 segments from around 30 hours of journalistic broadcast speech in French. The link between the duration of vowels and their spectral realization (through their f...

A Database for Automatic Persian Speech Emotion Recognition: Collection, Processing and Evaluation

Abstract   Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...

Prosodic and syntactic structures in spontaneous English speech

In this paper we examine prosodic and syntactic structures of spontaneous English speech. By wavelet-based analysis, the prosodic structure of speech can be visually represented as a tree diagram. Combined with automatic syntactic parsing, this enables a novel method to compare prosodic and syntactic hierarchical structures in spoken language. In our research we segmented a sample of spontaneou...
