The present disclosure relates to an audio interval detection apparatus and method, and a recording medium. The audio interval detection apparatus comprises a processor and a storage. The processor isconfigured to, by executing instructions stored in the storage, detect from a target audio signal a specified audio interval including a specified audio signal representing a state of a phoneme of asame consonant produced continuously over a period longer than a specified time, and by eliminating, from the target audio signal at least the detected specified audio interval, detect from the targetaudio signal a speech interval that includes a speech signal representing a speech uttered by a speaker. 本发明涉及声音区间检测装置、声音区间检测方法以及记录介质。声音区间检测装置具备：处理器；以及存储器，构成为通过执行该存储器中存储的命令，使得上述处理器执行以下的处理：从靶声音信号检测包括特定声音信号的特定声音区间，上述特定声音信号表示在比特定时间长的时间持续发出的同一子音的音素的状态，通过从上述靶声音信号至少除去检测出的上述特定声音区间，来从该靶声音信号检测包括语音信号的语音区间，上述语音信号表示由说话人发出的语音。
