i have problems with this too ive had some fun replacement words like foot towel instead of bath mat i have found some strategies that help me a little bit  i have scripts ive made up that i follow at work i even use the same jokes with customers  my partner i ask to have patience or just acknowledge and say im getting my words together so theyre not sitting around without context but also that ill say something think of a better way to say it say no wait that sounds wrong i more mean   everyone else im practising on them to get better at talking to the important people  its not perfect but i have less speaking induced anxiety so i hope that helps someone a little bit
