Do you find your voice wavering under pressure or running out of air mid-answer? By the end of this lesson you will be able to use diaphragmatic breathing and tactical inhales to sustain clear, steady, courtroom-ready testimony, control projection for both in-person and remote hearings, and apply breath-linked intonation and phoneme practice for maximum intelligibility. The lesson breaks down physiology and grounding, teaches practical 4–6 second and tactical-breath routines, and shows how to integrate projection, intonation, mic technique and rehearsal targets — with real examples and exercises to test and consolidate your skills. Read on for concise, evidence-led steps you can rehearse immediately.
