Abstract
Audible navigation system produces direction updates, scheduled at predetermined time windows, during which the audio environment is monitored for the existence of a conversation. If no conversations are detected during an update window, or lulls in conversation are detected, the audible navigation system direction update is output. If uninterrupted conversations continue as the update window time is expiring, a system volume is lowered and the navigation system direction update is output.
