PROBLEM TO BE SOLVED: To suppress interruption of response speech by erroneous detection of noise.SOLUTION: A speech dialog apparatus includes: a speech detection unit 8 that detects a start and an end of echo removed speech obtained by removing an echo of response speech contained in input speech; a response interruption control unit 11 that outputs a response interruption command if the end is not yet detected when a predetermined period from the detection of the start passes; and a dialog control unit 3 that causes a response speech output unit to interrupt output of the response speech upon receipt of the response interruption command from the response interruption control unit 11. |
