I've been reading on a lot of mainstream technology blogs, websites etc that Siri now vibrates when activated, as opposed to the double-beep we've all come to know and, occasionally, love, depending on how good Siri is to us. When experimenting with this, I discovered that when VoiceOver is enabled, the double-beep sounds are still there as usual. I tried disabling VoiceOver and indeed a vibration was all there was to announce Siri's activation. Additionally, since the launch of iOS 9, the double-beep has become slightly buggy, sometimes not sounding or sounding after a long delay. I presume this has something to do with the fact that it is only used by VoiceOver users. Does anyone know how I can disable the double-beep, and use the new vibrations? I must say that I prefer the virations over the beeps.
