Siri search disabling it

iOS and iPadOS

Hi all. i have an iPhone8+ and a strange issue. When I have my BARD app open, I mute sounds and turn off speech as to eliminate notifications. Anyway all of a sudden I hear this phrase, Siri search. It happens when I press home as it to get to the messages. If I swipe left, it says search field, but when i double tap nothing happens. I then see dictate, the messages, calendar, blah blah. so is there a way of getting rid of it? It makes me nuts. Thanks for any help. Oh and the version is 13.5
