To perform proper transmission of a language sound.SOLUTION: A voice transmission environment evaluation system 1 includes: an acoustic information acquisition unit 10 which acquires an acoustic signal containing language sounds which has passed a predetermined environment； and an evaluation unit 30 which calculates an evaluation value indicating a degree of the language sounds included in the acoustic signal. When a plurality of language sound components which are a plurality of mutually different components distributed based on frequency ranges with respect to the language sound are described using the acoustic signal, the evaluation unit 30 calculates the evaluation amount indicating a degree of the included language sounds for each language sound component, and calculates the evaluation value based on the evaluation amount corresponding to each language sound component.SELECTED DRAWING: Figure 2【課題】言語音の伝達を適切に行う。【解決手段】音声伝達環境評価システム１は、所定の環境を経た、言語音が含まれた音響信号を取得する音響情報取得部１０と、音響信号に言語音が含まれる程度を示す評価値を算出する評価部３０と、を有し、評価部３０は、言語音に関して周波数範囲に基づいて振り分けられた互いに異なる複数の成分である複数の言語音成分を、音響信号を用いて記述した際に、言語音成分それぞれについて言語音が含まれている程度を示す評価量を算出し、各言語音成分に対応する評価量に基づいて評価値を算出する。【選択図】図２
