A participant can be an effective speaker in a group discussion by speaking clearly and confidently, using simple language and staying focused on the main topic. They should also listen actively to others and build on their points instead of interrupting, which shows respect and collaboration. Maintaining positive body language, such as eye contact and an attentive posture, helps keep others engaged. Finally, contributing brief, well‑structured points and sometimes summarizing key ideas makes their input more impactful for the whole group.
