1. A speech-processing apparatus, comprising:

  • a processor configured to;

    localize a sound source based on an acquired speech signal; and

    perform speech zone detection in which a speech start and a speech end are detected based on localization information of the localized sound source,wherein the processor is configured to perform the speech zone detection by using a plurality of threshold values with respect to the localized speech signal, and whereinthe processor is configured to;

    detect a sound source candidate by using a first threshold value of the plurality of threshold values with respect to the localized speech signal,perform a clustering process on the detected sound source candidate, andperform the speech zone detection in which a speech start and a speech end are detected, by using a second threshold value that is larger than the first threshold value of the plurality of threshold values for each cluster classified by the clustering process.
