Abstract: A quality evaluation apparatus includes: a recording unit configured to record information indicating a state of a web browser in a storage unit at a plurality of timings; and a count unit configured to count the number of times reload operation is performed as an evaluation value of quality experienced by a user with reference to the storage unit, so that validity of the evaluation of experienced quality of web browsing is improved.

Abstract: An information output apparatus that is able to communicate with a terminal used by a subject of an experiment for evaluating quality of experience related to utilization of a web browser includes: an output unit configured to output a value of designated information out of information related to processing executed by the web browser of the terminal in accordance with operations. Thus, it is possible to simply acquire information related to processing performed by the web browser in response to arbitrary operations.

Abstract: A voice quality estimation apparatus includes: a packet sequence creation unit configured to create a first sequence by applying a first characteristic indicating that quality degradation caused by packet loss is perceived by a user all at once, to a sequence consisting of elements each indicating whether or not a packet of a voice call has been lost; a smoothing unit configured to create a second sequence from the first sequence; a degradation amount emphasis unit configured to create a third sequence from the second sequence; a packet loss tolerance characteristics reflection unit configured to create a fourth sequence from the third sequence; a degradation amount calculation unit configured to calculate a degradation amount from the fourth sequence; and a listening quality estimation unit configured to estimate voice quality that is to be experienced by the user, from the degradation amount.

Abstract: A voice quality estimation apparatus according to one embodiment includes: first sequence creation means for creating a first sequence by applying a first characteristic indicating that quality degradation caused by packet loss is perceived by a user all at once, to a sequence consisting of elements each indicating whether or not a packet of a voice call has been lost; second sequence creation means for creating a second sequence by applying a second characteristic indicating that the larger the quality degradation is, the more likely the user is to perceive the quality degradation, to the first sequence created by the first sequence creation means; third sequence creation means for creating a third sequence by applying a third characteristic indicating that packet loss concealment alleviates the quality degradation to be perceived, to the second sequence created by the second sequence creation means; calculation means for calculating a degradation amount per unit time from the third sequence created by the t
