The term 'SPEAKER's Need' can be broken down into three separate words: TWEETER (7 letters), Mike (4 letters), and INTRO (5 letters). TWEETER is a type of loudspeaker that produces high-frequency sound, usually used in audio systems. Mike is short for microphone, which is an electronic device used to capture sound. INTRO is short for introduction, which is the beginning of a speech or presentation. Together, these three words represent the equipment and preparation necessary for a successful public speaking event.
