An output sound abnormality detection apparatus includes an output sound generation circuit configured to generate a first sound and a second sound, the first sound being an output target and the second sound having same content as content of the first sound; an amplifier configured to amplify and output the first sound and the second sound; a comparator configured to compare signal levels of the first sound and the second sound output from the amplifier; and an abnormality determination circuit configured to determine whether there is an abnormality in one or both of the first sound generated by the output sound generation circuit and the amplifier based on a comparison result obtained by the comparator.
