Provided is a failure detection device (30) capable of detecting a failure of a sound generating device (10) even in a state where a sound is not output.A failure detection device (30) configured to detect a failure of a sound generating device (10) outputting a sound based on sound data from a speaker (11), includes: an electronic watermark signal generating means (23) configured to generate an electronic watermark signal including collation data used for collation of whether or not a sound is output from the speaker (11); the speaker (11) configured to output the electronic watermark signal as a sound; a microphone (12) configured to collect the sound output from the speaker (11); a collation data detection means (40) configured to detect the collation data from the electronic watermark signal included in the sound collected by the microphone (12); and a failure determination means (36) configured to determine presence or absence of the failure of the sound generating device (10), by collating the collation data detected by the collation data detection means (40), with the collation data included in the electronic watermark signal by the electronic watermark signal generating means (23).
