Under nerves, or after enough rehearsal that the words stop feeling alive, pitch tends to flatten into a narrow range near the bottom of your voice. To a listener, that reads as one of two things: disengagement, or discomfort — rarely as calm authority, which is usually what’s intended.
Natural intonation isn’t about performing enthusiasm. It’s allowing pitch to move the way it would in an ordinary, engaged conversation — rising slightly on a genuine question, falling to mark the end of a point, lifting on the word that actually matters in a sentence.
Try this now. Say the sentence “I didn’t expect that result” three times: once completely flat, once with the pitch rising and falling naturally as if telling a colleague something genuinely surprising, and once exaggerating the range further than feels comfortable. Record all three and notice which one sounds most like an actual person speaking, rather than which one felt most natural to produce.
Most people’s instinct under nerves undershoots range rather than overshoots it, which is why the exaggerated version in this exercise usually sounds closer to normal than expected.
