چکیده
L'introduction de connaissances dans les systèmes de reconnaissance de parole (RAP) est un bon m yen d'aeôliorer les performances des systèmes actuels . Dans cet article nous proposons le système ORION dans le cadre d'une application de reconnaissance multilocuteur de mots isolés . ORION est un système hybride à deux passes intégrant plusieurs sources de connaissances : psychoacoustiques, physiologiques et phonétiques. Pendant la première passe un modèle d'analyse acoustique perceptivement fondé (PLP), combinant des caractéristiques instantanées et des caractéristiques spectrales dynamiques, est utilisé pour fournir des vecteurs de paramètres à un algorithme de programmation dynamique . A l'issue de cette première passe plus de 98 % de mots ont été

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...
متن کاملمدل میکروسکوپی دوگوشی مبتنی بر فیلتر بانک مدولاسیون برای پیش گویی قابلیت فهم گفتار در افراد دارای شنوایی عادی
In this study, a binaural microscopic model for the prediction of speech intelligibility based on the modulation filter bank is introduced. So far, the spectral criteria such as the STI and SII or other analytical methods have been used in the binaural models to determine the binaural intelligibility. In the proposed model, unlike all models of binaural intelligibility prediction, an automatic ...
متن کاملSpeech Recognition using Acoustic Landmarks and Binary Phonetic Feature Classifiers
In spite of decades of research, Automatic Speech Recognition (ASR) is far from reaching the goal of performance close to Human Speech Recognition (HSR). One of the reasons for unsatisfactory performance of the state-of-the-art ASR systems, that are based largely on Hidden Markov Models (HMMs), is the inferior acoustic modeling of low level or phonetic level linguistic information in the speech...
متن کاملThe Effect of English Vowel-Recognition Training on Beginner and Advanced Iranian ESL Learners
This study was an attempt to investigate the effect of vowel-recognition training on beginner and advanced Iranian ESL learners. A total of 36 adult Iranian ESL learners (18 advanced and 18 beginners) who were students of various majors at Memorial University (MUN) were recruited for the study. Advanced participants had the experience of living in Canada for at least three years while beginners...
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 ...
