A more serious concern would be whether the audio/video format supports it, and if it does, whether client-side software can extract it. This approach also requires the audio/video file to be retrieved over the network, unless the textual alternatives are at the start (prior to the audio/video data). The latter is problematic for those with slow connections or strict band width quotas.
