Hey Siri is too short: it keeps getting triggered when people talk around. Furthermore, I have several iOS devices: I would like to have a different voice command for each device. Is there any way to rename the voice command
Hey Siri to turn on Siri?
There's no official way to rename the voice command to turn on Siri.
I've heard people discussing this after jailbreaking their devices, but I have no experience of that myself and wouldn't recommend it.
