Are there any other characters I can use in a <Say> verb to help the pronunciation (assuming I have too many options to just record them all as MP3s).
Thus far all I've found is hyphens to help with correctly detecting syllables: Adgrok is pronounced "Addbrooke" but "Ad-grok" is pronounced correctly. "PagerDuty" is "pahdgerduty" but "pager-duty" is correct.
Capitals seem to be meaningless and spaces can introduce weirdness: "Mont Re Al." is pronounced "Mont Re Alabama"
Unfortunately, at this time there are no special punctuation marks that can help with pronunciation.
