When the body is under stress, it contracts, which raises the pitch ! and also accentuates it.

The energy of the audience flows through you.

But if you record your own voice you will learn how you sound. You will accommodate the pressure, and lower your inflection.

It is better to approach the key tone from below, loosely, than to strike too high, “pitchy” they call it, hoping that hitting the notes is about reaching a pitch, an anxious woman hoping to please,

Instead of a confident woman who has done the work, whose voice wavers in the havoc(!) of the audience, but slides skillfully into what the audience demands.

Know and respect your parasympathetic nervous system! Loosen up, so you can tighten up!
