To appropriately determine that a user wearing an earphone is called.SOLUTION: An external sound processing device includes: a conversion section for acquiring voice uttered by an utterer on an outer side of an earphone and converting the voice into external voice data being voice data; a determination section for performing first determination to determine whether a user of the earphone is called or not based on a coincidence degree between the external voice data and registration data obtained by converting voice when a predetermined registered person calls the name of the user of the earphone into voice data, and performing second determination which is different from the first determination to determine whether the user of the earphone is called or not when it is determined that the user of the earphone is not called in the first determination; and a processing section for performing external sound fetching processing to fetch voice generated on an outer side into the earphone when it is determined that the user of the earphone is called in the first determination or the second determination.SELECTED DRAWING: Figure 2 【課題】イヤホンを装着した使用者が声を掛けられたことを適切に判定する。【解決手段】外音処理装置は、イヤホンの外部で発声者が発した声を取得し、音声データである外声データに変換する変換部と、外声データと、所定の登録者がイヤホンの使用者の呼び名を発声した声を音声データに変換した登録データとの一致度に基づいてイヤホンの使用者が声を掛けられたか否かの第１判定を行い、第１判定でイヤホンの使用者が声を掛けられていないと判定された場合、イヤホンの使用者が声を掛けられたか否かについて第１判定とは異なる第２判定を行う判定部と、第１判定又は第２判定において、イヤホンの使用者が声を掛けられたと判定された場合、外部で生じる音声をイヤホンに取り込む外音取込処理を行わせる処理部とを備える。【選択図】図２
