Highly Recommend this extenstion. Very good pronunciation compared to the other two of the three available. I will say i believe it sounds more like a UK English accent which i was fine with. Compared to "Speak it" and "Speak Text" sounds more unnatural and very computer like speaking. Oribi Speaks more natural compared to the other two.
