Abstract
The HINT provides an efficient and reliable method of assessing speech intelligibility in quiet and in noise by using an adaptive strategy to measure speech reception thresholds for sentences, thus avoiding ceiling and floor effects that plague traditional measures performed at fixed presentation levels. A strong need for such a test within the Canadian Francophone population, led us to develop a French version of the HINT. Here we describe the development of this test. The Canadian French version is composed of 240-recorded sentences, equated for intelligibility, and cast into 12 phonemically balanced 20-sentence lists. Average headphone SRTs, measured with 36 adult Canadian Francophone native speakers with normal hearing, were 16.4 dBA in quiet, −3.0 dBA SNR in a 65 dBA noise front condition and −11.4 dBA SNR in a 65 dBA noise side condition. Reliability was established by means of within-subjects standard deviation of repeated SRT measurements over different lists and yielded values of 2.2 and 1.1 dB for the quiet and noise conditions, respectively.

Sumario
El HINT aporta un método eficiente y confiable de evaluación de la inteligibilidad del lenguaje en silencio y en ruido, utilizando una estrategia de adaptación para medir los umbrales de recepción del lenguaje para frases, evitando así los efectos de techo y piso que influyen en las mediciones tradicionales realizadas a niveles fijos de presentación. La gran necesidad de una prueba así para la población canadiense francófona nos llevó a desarrollar una versión francesa del HINT. Aquí describimos el desarrollo de esta prueba. La versión en francés canadiense está constituida por 240 frases grabadas, ecualizadas para la inteligibilidad, y organizada en 12 listas de 20 frases fonénicamente balanceadas. Los SRT promedio con auriculares, medidas en 36 adultos hablantes naturaies del francés canadiense y con audición normal, fueron de 16.4 dBA en silencio, de–3.0 dB SNR en una condición de ruido frontal a 65 dBA, y de–11.4 dBA SNR in una condición de ruido lateral a 65 dBA. La confiabilidad se estableció por medio de la desviación estándar intra-sujeto de mediciones repetidas del SRT con diferentes listas, lo que produjo valores de 2.2 y 1.1 dB en condiciones de silencio y de ruido, respectivamente.
