after IOS13.1 update, phone still makes 'bubble ' 'autocorrect ' noise

Hi
Please help?
after updating have noticed some improved stability with BSI on iphone, I have turned every single variant of predictive text I can think of off, apart from the, ' check spelling ' feature, but still, phone makes noises, when typing in BSI, like my phone has autocorrect/predictive text, switched on
I like to think of myself as fairly knowledgeable when it comes to VO on IOS, but please, someone tell me there's something I'm doing wrong?
Many thanks for reading, and in advance for responses
