PROBLEM TO BE SOLVED: To provide a person having articulation disturbance with a speech production recognition system.SOLUTION: A speech production recognition system is used for an object person and includes an accessory 3, an image acquisition device 4, an intraoral detector 5, and a speech production recognition device. The image acquisition device 4 acquires the image of the lip of the object person during speech production of the object person. The intraoral detector 5 detects contact with the tongue of the object person and a distance from the tongue of the object person to generate a contact signal and a distance signal. The speech production recognition device processes the image of the lip, the contact signal, and the distance signal to acquire content of speech production of the object person.SELECTED DRAWING: Figure 1【課題】構音障害を有する人に発話認識システムを提供する。【解決手段】発話認識システムは、対象者に用いられ、装身具３と、画像取得装置4と、口腔内検知装置5と発話認識装置とを含む。画像取得装置4は、対象者の唇の画像を対象者の発話中に取得する。口腔内検知装置5は、対象者の舌との接触と対象者の舌との距離を検知して接触信号と距離信号とを生成する。発話認識装置は、唇の画像と接触信号と距離信号とを処理して対象者の発話内容を取得する。【選択図】図１
