Telephone accessory for generating conversation utterances to a remote listener in response to a quiet selection

摘要

A user conducts a telephone conversation without speaking. It does this by moving the participant in the public situation to a quiet mode of communication (e.g., keyboard, buttons, touchscreen). All the other participants are allowed to continue using their usual audible technology (e.g., telephones) over the existing telecommunications infrastructure. The quiet user interface transforms the user's silent input selections into equivalent audible signals that may be directly transmitted to the other parties in the conversation.
