Automatic intelligibility measures applied to speech signals simulating age-related hearing loss
International audienceThis research work forms the first part of a long-term project designed to provide a framework for facilitating hearing aids tuning. The present study focuses on the setting up of automatic measures of speech intelligibility for the recognition of isolated words and sentences. Both materials were degraded in order to simulate presbycusis effects on speech perception. Automatic measures based on an Automatic Speech Recognition (ASR) system were applied to an audio corpus simulating the effects of presbycusis at nine severity stages. The results are compared to reference intelligibility scores collected from 60 French listeners. The aim of this system being to produce measures as close as possible to human behaviour, good performances were achieved since strong correlations between subjective and objective scores are observed
Comparaison de mesures perceptives et automatiques de l'intelligibilité : application à de la parole simulant la presbyacousie
International audienceCet article présente une étude comparative entre mesures perceptives et mesures automatiques de l'intelligibilité de la parole sur de la parole dégradée par une simulation de la presbyacousie. L'objectif est de répondre à la question : peut-on se rapprocher d'une mesure perceptive humaine en utilisant un systÚme de reconnaissance automatique de la parole ? Pour ce faire, un corpus de parole dégradée a été spécifiquement constitué puis utilisé pour des tests perceptifs et enfin soumis à un traitement automatique. De fortes corrélations entre les performances humaines et les scores de reconnaissance automatique sont observées
Encantamento do rosto: poses e retratos de cinema
The purpose of this article is to describe a set of photographs of Eliane Lage (1928-), a movie actress featured in Caiçara, Ăngela, SinhĂĄ Moça and Ravina - the first three produced by Companhia CinematogrĂĄfica Vera Cruz (1950-1954), and the fourth by CinematogrĂĄfica Brasil Filmes. Companhia CinematogrĂĄfica Vera Cruz aspired to be one of the largest film producers in Brazil and, accordingly, its Advertising Department set out to establish Eliane Lage as a great movie star, like those in the world's dominant movie industries. This paper brings to light some photographs which, coupled with information published in the press, were intended to tell the public at large who Eliane Lage was by exploring extensively certain aspects of her "biography", such as her privileged background, her denial of stardom, her detachment, her passion for her husband, and her love of nature. The picture selection includes: a photo essay by the architect Gregori Warcharchik; studio marketing photographs; snapshots taken by photographers at the time; and pictures that are part of the actress's personal collection
