Overview:
When VoiceOver iOS 10.1 user sets focus on an ARIA slider element with aria-valuetext="68 degrees" VoiceOver will not speak "68 degrees" it only speaks "68, 36 percent". If you place a non-digit string in the front e.g. aria-valuetext="Currently 68 degrees" then VoiceOver speaks it correctly. So starting with a digit in the value breaks the support. 

This does not affect macOS. 

Steps to Reproduce:
1. Enable VoiceOver on iOS 10.1
2. Visit https://www.w3.org/TR/wai-aria-practices-1.1/examples/slider/slider-2.html in Safari iOS
3. Set VoiceOver focus to the 68 degrees slider.

Expected Results:
VoiceOver iOS speaks: "Temperature 68 degrees, adjustable, swipe up or down with one finger to adjust the value"

Actual Results:
VoiceOver iOS speaks: "Temperature 68, 36 percent, adjustable, swipe up or down with one finger to adjust the value"
