Teacher voice and speech – UGC NET Question

Statements A, B and D are correct, whereas C is incorrect. A is true because changes in tone and emphasis alert students to key ideas and prevent boredom. B is true since a flat, monotonous voice tends to reduce attention and engagement. D is true as clear articulation allows learners to catch the wording of important concepts and definitions. C is false because speaking very fast constantly can overwhelm students and does not necessarily indicate effective teaching.

Option A:
Option A is correct because it brings together A, B and D, the three statements that accurately describe desirable aspects of teacher voice. It purposely omits C, which promotes an unhelpful view of speed over comprehension. Therefore this option reflects the correct set of statements.

Option B:
Option B is incorrect because it includes only A and B and omits D, ignoring the importance of clarity and articulation. Without D, the portrayal of effective speech in teaching is incomplete. Hence A and B only cannot be accepted.

Option C:
Option C is incorrect because it groups B and D only and leaves out A. While B and D are accurate, excluding A neglects the role of tonal variation in maintaining interest and highlighting key points. As a result, B and D only is not a full answer.

Option D:
Option D is incorrect because it treats all four statements as correct, including C. Since C wrongly claims that constant high speed is always desirable, the option mixes a false statement with true ones and must be rejected.
