I connect my phone to a Bluetooth speaker to play music. When engage Siri or try to use dictation, the phone wants to use the microphone on the Bluetooth device, which is either too crappy or too far away for it to understand what I am saying.
So, I would like a way to restrict the iPhone to using its own microphone even when connected to a Bluetooth speaker.
I am open to doing this via a setting, buying an app, or jailbreaking or whatever.
Is there a way to do this?
