Summary:PROBLEM TO BE SOLVED: To reduce the possibility of confidential information leaking to the outside when uttered speech data is transmitted to a speech recognition server and also recognize the speech and turn it into text with sufficient accuracy, as well as reduce the load of a speech recognition and text conversion process performed by an internal information processing terminal and secure a processing speed.SOLUTION: A data processing device 1 comprises: a speech data replacement unit 26 for replacing specific part speech data included in acquired speech data with replacement part speech data different from the specific part speech data, and outputting it as speech data for conversion; a communication unit 30 for transmitting the speech data for conversion to a speech recognition server, and receiving text data converted from the speech data for conversion from the speech recognition server; and a text data reverse replacement unit 31 for extracting post-replacement text data, among the text data inputted from the speech recognition server, that corresponds to the replacement part speech data, and replacing the post-replacement speech data with pre-replacement text data that corresponds to the specific part speech data and outputting the resulting speech data.SELECTED DRAWING: Figure 2 【課題】音声認識サーバに発話音声データを送信する際の機密情報の外部への漏洩の可能性を低減し、かつ十分な精度で音声認識・テキスト化する。なおかつ、内部の情報処理端末が行う音声認識・テキスト化の処理の負荷を軽減し、処理スピードを確保する。【解決手段】データ処理装置１は、収音音声データに含まれる特定部音声データを、特定部音声データとは異なる置換部音声データに置換し、変換用音声データとして出力する音声データ置換部２６と、変換用音声データを音声認識サーバへ送信し、変換用音声データから変換されたテキストデータを音声認識サーバから受信する通信部３０と、音声認識サーバから入力されたテキストデータのうち、置換部音声データに対応する置換後テキストデータを抽出し、特定部音声データに対応する置換前テキストデータへ置換後音声データを置き換えて出力するテキストデータ逆置換部３１とを備える。【選択図】図２
