*Next time you are in a session, try to keep track by tallying or recording the number of times you say "ok."  In graduate school we were required to tally how many times "ok" was used during one of our therapy session.s Now I am more conscious of not overusing the word "ok" during sessions.  Instead I try to state something specific that I want the client to work on and/or specific positive reinforcement.  It is challenging sometimes, but I think it helps to develop the skills of the client and the therapist. 

*Example: Client produces the /b/ sound correctly.  Instead of saying "ok good" you could say, " P I really like the way you put your lips together to make the /b/ sound" or "Wow, I can see you have really been practicing the /b/ sound." 

*Reinforcement can be modified for each client, but the goal is to reduce the number of times "ok" is being used in the session.
