On my work iphone 6 and my personal Iphone 5s the voiceover sounds very computerised suddenly. I have it on the British english voice as I am in the UK instead of it sounding natural and fluid like it always did everything sounds muffled and very computerised. It can't be the speaker as my work iphone 6 is brand new and my iphone 5s does the same thing. Even my wife's iphone 5s has it when I borrowed it and turned voiceover on. Has anyone else experienced this problum and even better do you know of a fix?
