1. Get on a page
2. Click "Read Page"
3. Wait for it to buffer and read some text
4. While it's reading, change the selected voice in the dropdown list (i.e. from Male 1 to Male 2)
5. Hear that the voice stays the same even once it switches to the next paragraph
6. Hear that pausing doesn't change things either
7. Hear that only making it stop and re-read page actually changes the voice
