speak auto text talking too fast

We tried that and it didn't change anything. Even the voice didn't change. So I just now tried installing the Alex voice and it doesn't change anything either. It was still the exact same voice. You would think the Alex voice would be a guys voice but it was still the same fast talking Siri voice. So I tried powering down the phone by holding down the home button and power button until the Apple logo shows up and wait for it to reset. Still no success. Alex still sounds like the broken Siri voice. Tried some of the other English language voices like UK and south Africa and still no success. I have spoken with 2 different Apple technicians on the phone and they keep referring it to another department higher up the food chain. It's been a couple weeks now and I don't think they are going to call me back.

So it's doing this on my iPhone 6 plus and my girlfriend's iPhone 6 plus and just out of curiosity I checked to see if it was doing it on our iPad mini 2 and sure enough it was. I don't even use the feature but my girlfriend insists on using it on her devices and it always scares the crap out of me when Siri screams out gibberish when trying to autocorrect a word. There's no volume control for Siri so whenever we're in a nice quiet setting and out of nowhere this screaming voice on fast forward blurts out......"Capital I.....Capital, Capital, Capital I. She usually stutters the word a couple times and it can really make a person jump when this happens.

I guess I'll have to call Apple back about this.
