Cued Speech Enhances Speech-in-Noise Perception

Abstract : Speech perception in noise remains challenging for Deaf/Hard of Hearing people (D/HH), even fitted with hearing aids or cochlear implants. The perception of sentences in noise by 20 implanted or aided D/HH subjects mastering Cued Speech (CS), a system of hand gestures complementing lip movements, was compared with the perception of 15 typically hearing (TH) controls in three conditions: audio only, audiovisual and audiovisual + CS. Similar audiovisual scores were obtained for signal-to-noise ratios (SNRs) 11dB higher in D/HH participants compared with TH ones. Adding CS information enabled D/HH participants to reach a mean score of 83% in the audiovisual + CS condition at a mean SNR of 0 dB, similar to the usual audio score for TH participants at this SNR. This confirms that the combination of lipreading and Cued Speech system remains extremely important for persons with hearing loss, particularly in adverse hearing conditions.
