I recently installed iOS 7.1 and I use the South African English voice for Voice Over. The unfortunate part is that I can no longer adjust the speaking rate on the South African Voice. all other voices, e.g British, Australian, Irish and even the US one can adjust the speaking rate.
To this end, I am forced to use the British and US voices as the south African voice speaks at an incredibly fast rate and there is no way of adjusting the rate. This, happens despite having adjusted the speaking rate at the slowest, the south african voice is not affected by this at all and continues to speak at an alarmingly fast rate. Can you do something about this?
