Tips

If application has audio indicators, such as a bell sound, a visual indicator might be required as well. For eg: Chat Window

Sounds, cues brought by musical shifts, or tone should be included in Subtitles.

If a sound is vital to the application, the mute button might flash or display a message.

Transcripts are not useful only for users with aural disabilities but for the users with quasi disabilities such as No speaker or Network restrictions
