Infrared lasers generate compound action potentials from neurons with heat-sensitive channels and stimulate nerves without contacting tissues; therefore, an infrared laser-based hearing aid can produce auditory perception without requiring electrode insertion into the cochlea. The purpose of this study was to develop a speech-coding scheme using infrared laser stimulation to convey intelligible speech. Because the laser stimulation has a limited capacity to stimulate auditory neurons differentially, it evokes action potentials from the entire cochlear nerve simultaneously. Thus, the stimulation may be perceived as a clicking sound. We therefore created a click-modulated speech sound to simulate infrared laser stimulation. The sound was a repetitive click with a pitch (repetition rate) and amplitude similar to the formant frequency and amplitude envelope transition of an original speech sound, respectively. Five Japanese native speakers with normal hearing participated in the experiment. First, the subjects listened to the click-modulated speech sounds and answered questions about what they perceived, selecting from four choices; second, they listened to the sound and wrote down what they perceived, using the Roman alphabet. The percentages of correct answers on both the alternative-choice and dictation tests were significantly higher than the rates obtained by chance. Our data suggests that click-modulated speech sounds were at least partially intelligible, and that a hearing aid with an infrared laser could restore speech perception in hearing-impaired individuals.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000016914","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
