The AzBio is a sentence test that has been widely adopted by clinical teams to evaluate speech recognition performance in adults with hearing impairment. The goal of this work was to develop and normalize an international French version of the AzBio sentence test following the same steps used in creating the original test. The initial FrBio corpus included 1000 sentences generated by in-ternational French speaking collaborators and recorded with two female and two male talkers. The mean intelligibility of each sentence was estimated by processing each sentence through a four-channel cochlear implant (CI) simulation and calculating the mean percent correct score achieved by 16 normal-hearing listeners in France and Canada. Sentences from each talker were sorted by percent correct score, and 165 sentences were selected from each talker and then sequentially as-signed to 33 lists, each containing 20 sentences (5 sentences from each talker). List equivalency was validated by presenting all lists, in random order, to 30 listeners with normal hearing and 25 listeners with varying degrees of hearing impairment in France and Canada. The 33 lists of sen-tences had a mean intelligibility score of 85% with normal hearing listeners. The results of the vali-dation study with normal hearing and hearing-impaired listeners revealed no significant differences in percent correct scores for 30 of the 33 sentence lists.
