We have been testing some stuff we'll be rolling out soon. A teammate had the idea to split test foreign accented voices vs. American for our Interactive and Messenger products. After leaving 1,000 voicemails, the British girl kicked the American girls' butt - using identical script to identical vertical. The British chick also kicked the American girls' butt in the Interactive (Press 1 on steroids) testing.

So, word to the wise; hire British actresses to do your recordings!
