You can change how quickly or when Siri responds, use text to make requests to Siri, have Siri listen for atypical speech patterns, have Siri audibly share notifications, and announce and end calls.
Go to Settings Change when Siri responds.
Go to Settings activate Siri, then interact with Siri using the keyboard and text field.
You can have Siri listen for atypical speech. This may be helpful if you have an acquired or progressive condition that affects speech, such as cerebral palsy, amyotrophic lateral sclerosis (ALS), or stroke.
Go to Settings supported headphones, and on > Accessibility > Siri, tap Call Hangup, then turn on Call Hangup.
