'GLIDE SLOPE' Annunciation at 500 ft. on approach below cloud deck. Deviation was due to a gust or possible wake turbulence. Aircraft was approximately one dot low on GS (glide slope); and we got the aural warning. By the time we would have executed a go-around; aircraft was back on glide slope and all other parameters. We continued the approach; as a go-around would have complicated the situation; as the deviation had already resolved.
A319 First Officer reported a momentary excursion below the glide slope on approach; due to possible wind gust or wake encounter.
