Good but with faults
It's one of the best to choose but makes mistakes when coming to different features of sentences. Mathematical components can be ignored especially powers so incorrectly reads a sun then can read abreviations as a non existent word in the sentence at times while another time as the abbreviation even if they are common. It also rapidly reads through bullet points never pausing one after another as they should be heard as separate sentences. Sometimes the GB voices are making pronounciation of specific words how an American or some other country would pronounce it not UK English. This is all no different on the internet browser installed or pc downloaded versions do make mistakes. If these mistakes were tidied up it would be perfected widening it's capabilities so reducing all the mistakes I've experienced it making.
