Introduce Math capital pitch option

I use ESpeak-NG with NVDA and have Capital pitch change percentage set to 30 (probably default) in NVDA's Voice Settings. Capitals in Math (therefore likely processed by Math CAT) are spoken at way higher a pitch than the increased pitch at which capitals are otherwise read, to the point that Math capitals can sometimes be a bit challenging to understand. While there may be an argument to be made about how Math capitals should be spoken at an even higher pitch to make the contrast clearer since capitalization is more vital in Math than in general contexts, I think: (a) the current pitch change sounds excessive with ESpeak-NG to me, and (b) making this user-customizable would overcome the subjectivity of individual preferences.
