By default we do not speak passwords if the user has no headset. However, many users find this too restrictive and would like a way to enable password announcement. While we cannot speak the passwords all the time ,to avoid leaking them, we expose a preference so each user can choose the option that best works for him/her. bug:5712607 Change-Id: I6eb0c40834abe5297f7dc74be02d180a5bef0174
