To provide technology for changing a voice recognition range to be suitable to a viewing stye of a user in a display device with a voice recognition function.SOLUTION: A display device with a voice recognition function, having a display section, comprises a voice input section which: has directivity, sets an orientation direction being a direction of directivity to a prescribed angle, performs voice acquisition in parallel for a plurality of times, in which angles of voice recognition differ, which selects candidate voice data in accordance with a feature amount of voice data from voice data acquired by the voice acquisition, sets the orientation direction of the candidate voice data to be a speaker direction, discriminates whether or not valid voice data is a keyword voice, performs the voice acquisition in which the speaker direction is set to be the orientation direction and acquires a command voice. The display device comprises: a narrow angle mode in which a voice acquisition range by the voice acquisition for the plurality of times is narrow; and a wide angle mode in which the voice acquisition range by the voice acquisition for the plurality of times is wide, and the display device is configured to allow the narrow angle mode and the wide angle mode to be switched.SELECTED DRAWING: Figure 1 【課題】音声認識機能付き表示装置において、使用者の視聴スタイルに合わせて、音声認識範囲を変えられる技術。【解決手段】 表示部を持つ音声認識機能付き表示装置であって、指向性を持ち、指向性の方向である指向方向を所定の角度に設定し音声取得を、並行して複数回行い、それぞれの該音声取得の該角度は異なり、該音声取得によって取得した音声データの中から、該音声データの特徴量に応じて候補音声データを選定し、該候補音声データの指向方向を発話者方向とし、該有効音声データがキーワード音声か否かを判別し、該発話者方向を指向方向とした該音声取得を行い、コマンド音声を取得する音声入力部を備え、複数の該音声取得による音声取得範囲が狭い狭角度モードと、複数の該音声取得による該音声取得範囲が広い広角度モードと、を備え、該狭角度モードと該広角度モードを切り替え可能であることを構成とする。【選択図】図１
