Please Apple, Make that beep optional (through settings, perhaps at the accessibility section).
I use my iPod every day and I discovered Siri could be very useful for my mother. My mother became gradually blind a few years ago and now she can't see at all. Before purchasing her an iPhone I trained her on my iPod Touch to use Siri and finally, after saving for a few months, I purchased her an iPhone SE just last week.
I became very frustrated when I discovered that, despite having the same operating system on my iPod Touch, she cannot enjoy of a beep alerting her that she can start talking to Siri on her iPhone.
Please Apple, make that Siri beep optional. A few lines of code from your side will potentially make life far more accessible to Blind people (specially the ones that become blind in the middle of their lives which, by 2014 were about 3 million only in the United States).
Thank you in advance.
