A speaking cuff is a device used to amplify and clarify speech. It is commonly used by people who have difficulty speaking clearly or loudly, such as those with Parkinson's disease or a speech impediment. Some synonyms for a speaking cuff include a speech amplifier, voice enhancer, talking aid, and communication device. These devices can be useful in a variety of settings, including classrooms, business meetings, and social gatherings. While a speaking cuff is an effective tool for those who need it, it's important to remember that everyone has the right to communicate and be heard, regardless of whether or not they use a device.
