Web Speech API output should use Cortana's voice
For Consistency, the Web Speech API for voice output to read page content should be Cortana
Erin Young commented
I think we users should have a chose of the voice. Cortana's voice is monotone and I personally like British speaking man or woman. Furthermore how about our own voice or other we know. More comfort in directions and taking to, when the voice is a familiar person.
Thanks, Erin Young
