I’m a bit stunned that Apple hasn’t taken this low hanging fruit (pardon the pun). Siri is there hiding in the right hand side of my screen and there could be an easier way of interacting with it.
Yes, there are ways of creating a macro to get Siri to run via voice. It’s a hack and the latency / response time is likely long. However, this is something that could allow Siri to jump closer to Cortona/Alexa/Google Assistant, especially among non-iPhone users.
Apple voice team, where are you?
