A sponsorship credit display detection device 100 according to the present invention includes: a related phrase storage unit 120 that stores related phrases included in announcement of a sponsorship credit display and related to the sponsorship credit display, in association with estimation periods; a voice recognition unit 140 that performs voice recognition on an audio signal of the broadcast program; a related phrase detection unit 150 that detects a stored related phrase from results of the voice recognition; a sponsorship credit display segment estimation unit 160 that, using an appearance time of the detected related phrase as a start point, estimates a period corresponding to the estimation period stored in association with the detected related phrase as a sponsorship credit display segment; and a detection unit 170 that, among estimated sponsorship credit display segments, detects a segment that continues for at least a predetermined time period as a sponsorship credit display segment. ## Claims ### Claim 1 A sponsorship credit display detection device for detecting, in a broadcast program, a sponsorship credit display segment where a sponsorship credit display indicating a sponsor of that broadcast program has been displayed, the device comprising: a related phrase store configured to store a related phrase included in an announcement of the sponsorship credit display and related to the sponsorship credit display, in association with an estimation period where at least one predetermined period before or after an appearance time of the related phrase is estimated as the sponsorship credit display segment; a voice recognizer configured to recognize voice on an audio signal of the broadcast program; a related phrase detector configured to detect a related phrase stored in the related phrase store from results of the voice recognition by the voice recognizer; a sponsorship credit display segment estimator configured to, using an appearance time of the related phrase detected by the related phrase detector as a start point, estimate a period corresponding to the estimation period stored in the related phrase store in association with the detected related phrase as the sponsorship credit display segment; and a detector configured to, among sponsorship credit display segments estimated by the sponsorship credit display segment estimator, detect a segment that continues for at least a predetermined time period as the sponsorship credit display segment. ### Claim 2 (depends on 1) The sponsorship credit display detection device according to claim 1, further comprising: an image recognizer configured to estimate the sponsorship credit display segment based on a video signal of the broadcast program, wherein the detector, among segments obtained by a logical sum operation or a logical product operation of the sponsorship credit display segment estimated by the sponsorship credit display segment estimator and the sponsorship credit display segment estimated by the image recognizer, is configured to estimate a segment that continues for at least a predetermined time period as the sponsorship credit display segment. ### Claim 3 (depends on 1) The sponsorship credit display detection device according to claim 1, wherein the estimation period of the related phrase is set according to a position where the related phrase is likely to appear in the announcement of the sponsorship credit display. ### Claim 4 (depends on 1) The sponsorship credit display detection device according to claim 1, wherein the detector outputs time information of the detected sponsorship credit display segment. ### Claim 5 A sponsorship credit display detection method in a sponsorship credit display detection device that detects, in a broadcast program, a sponsorship credit display segment where a sponsorship credit display indicating a sponsor of that broadcast program has been displayed, the method comprising: storing a related phrase included in an announcement of the sponsorship credit display and related to the sponsorship credit display, in association with an estimation period where at least one predetermined period before or after an appearance time of the related phrase is estimated as the sponsorship credit display segment; performing voice recognition on an audio signal of the broadcast program; detecting the stored related phrase from results of the voice recognition; using an appearance time of the detected related phrase as a start point, estimating a period corresponding to the estimation period stored in association with the detected related phrase as the sponsorship credit display segment where the sponsorship credit display has been displayed; and detecting a segment where the estimated sponsorship credit display segment continues for at least a predetermined time period as the sponsorship credit display segment. ### Claim 6 (depends on 5) The sponsorship credit display detection method according to claim 5, the method further comprising: estimating the sponsorship credit display segment based on a video signal of the broadcast program, estimating, among segments obtained by a logical sum operation or a logical product operation of the sponsorship credit display segment estimated in the first estimation step and the sponsorship credit display segment estimated in the second estimation step, a segment that continues for at least a predetermined time period as the sponsorship credit display segment. ### Claim 7 A computer program causing a computer to function as the sponsorship credit display detection device, the device comprising: a related phrase store configured to store a related phrase included in an announcement of the sponsorship credit display and related to the sponsorship credit display, in association with an estimation period where at least one predetermined period before or after an appearance time of the related phrase is estimated as the sponsorship credit display segment; a voice recognizer configured to recognize voice on an audio signal of the broadcast program; a related phrase detector configured to detect a related phrase stored in the related phrase store from results of the voice recognition by the voice recognizer; a sponsorship credit display segment estimator configured to, using an appearance time of the related phrase detected by the related phrase detector as a start point, estimate a period corresponding to the estimation period stored in the related phrase store in association with the detected related phrase as the sponsorship credit display segment;
