To improve convenience when issuing a voice instruction to an in-vehicle device.SOLUTION: An in-vehicle device (in-vehicle audio device 100) includes: a first speech recognition unit configured to recognize a word indicating the in-vehicle device and a word indicating first instruction contents among words indicating instruction contents for operating the in-vehicle device by speech recognition, based on an input voice; and a second speech recognition unit configured to operate in response to the word indicating the in-vehicle device recognized by speech recognition and recognize a word indicating second instruction contents for operating the in-vehicle device by speech recognition, based on a voice input after the word indicating the in-vehicle device. The first speech recognition unit recognizes the word indicating the first instruction contents, regardless of an occurrence order in relation to the word indicating the in-vehicle device.SELECTED DRAWING: Figure 3

    【課題】車載装置に対して音声指示を行う際の利便性を向上させる。【解決手段】車載装置(車載オーディオ装置100)は、入力された音声に基づき、車載装置を示すワード及び車載装置を操作するための指示内容を示すワードのうちの第1の指示内容を示すワードを音声認識する第1の音声認識部と、車載装置を示すワードが音声認識されたことで動作し、車載装置を示すワードに続いて入力された音声に基づき、車載装置を操作するための第2の指示内容を示すワードを音声認識する第2の音声認識部と、を有する。第1の音声認識部は、車載装置を示すワードに対する出現順序に関わらず、第1の指示内容を示すワードを音声認識する。【選択図】図3
