This document presents a proposal for a new smart bracelet device called the "Speaking Bracelet". The bracelet would allow users to receive calls and messages from their phone without needing to take their phone out, as it connects wirelessly. It has a built-in microphone so users can talk or record voice messages. The bracelet also tells time, plays music, and sends reminders. It is presented as a potential new product from a fictional company called "Qwerty" by two students as part of a school project. They conducted a survey that found many people struggle to use their phones conveniently in certain situations, so this bracelet could solve that problem while having additional useful functions.
