To obtain an appropriate evaluation value in an acoustic quality evaluation by a conversational test. An acoustic quality evaluation apparatus 3 evaluates the acoustic quality of a call performed between a near-end terminal 1 and a far-end terminal 2 via a voice communication network 4. An evaluation value presenting unit 31 displays, on a display unit 13, evaluation categories obtained by classifying each of a plurality of evaluation viewpoints into a predetermined number of levels. An input unit 14 transmits the evaluation category selected by the evaluator for each of the evaluation viewpoints, to an evaluation value determination unit 32. The evaluation value determination unit 32 determines the lowest evaluation value among evaluation values assigned to the evaluation category received from the input unit 14 as a subjective evaluation value for acoustic quality.
An acoustic quality evaluation apparatus configured to obtain, from an evaluator, a subjective evaluation value of acoustic quality of a call performed between a plurality of communication terminals, the apparatus comprising:
An acoustic quality evaluation method for obtaining, from an evaluator, a subjective evaluation value of acoustic quality of a call performed between a plurality of communication terminals, the method comprising:
