Hey, @userOTdYnS6UTV, thanks for reaching out about this. Let's go over a few quick options to see if they help. Would you mind going to Bixby Home > tap the three dots in the top right > Settings > Voice Wake-up? On this page you will find an option to Improve voice wake-up accuracy, as well as an option to change the Wake-up Sensitivity.
Let us know if this helps. Thanks!
