Latency when calling Voice.start() on iOS

On iOS I'm experiencing around a 0.5s delay from the moment I call Voice.start() until speech starts being recognized.

As an improvement, we could try to improve the performance of the setupAndStartRecognizing native function on iOS, since it does seem to be slower than the native dictation keyboard.

May I ask, have you been able to improve / reduce the delay?
