Different voice for punctuations?
His appears to be something new in 9.3 tha is VO related. I'm noticing that punctuations and paces are being announced in a different voice now. I use Alex for my main voice, and am hearing Daniel announcing if I read over a punctuation. Not sure if this is a setting with VO, or with the speak screen option or what, and if any setting regarding this can be changed.
This is a known bug that has been talked about in the main page relating to iOS 9.3.
