Summary:To realize voice recognition by separating voices of multiple speakers.SOLUTION: The voice recognition device is a voice recognition device having a processor and a memory, which includes a voice feature amount calculation unit which calculates a first voice feature amount from first voice data in which voices of a plurality of speakers are mixed, utterance order information which stores dictation data of each voice contained in the first voice data and an utterance order of each voice, and a learning unit which learns an acoustic model based on the first voice feature amount and the utterance order information.SELECTED DRAWING: Figure 2 【課題】複数の話者の音声を分離して音声認識を実現する。【解決手段】プロセッサとメモリを有する音声認識装置であって、複数の話者の音声が混合された第１の音声データから第１の音声特徴量を算出する音声特徴量算出部と、前記第１の音声データに含まれる各音声の書き起こしデータおよび各音声の発話の順序を格納した発話順序情報と、前記第１の音声特徴量と前記発話順序情報に基づいて音響モデルを学習する学習部と、を有する。【選択図】図２
