I worked as a call center employee for about 9 years and a month or two. It was weird at first, but once I got more experience with it, I was able to get better at giving canned responses which I'd been able to rehearse. As I got more and more familiar with the terminology, scripts, etc, it became easier. I also found that as it got easier to say the things I had been able to practice, it also got easier to talk in general, which helped bring my anxiety down in my day to day life. Call center work isn't for everyone, but I think if you stick with it for awhile it does have its benefits for people like us who struggle with their speech. It's kind of like just being able to practice talking to people all day, and the best part is that with most call center jobs, you won't have to ever talk to that same person again after that call. Side note, I went on to become a manager at that call center, and now I'm a pilot working on my certification to become a flight instructor. The stuttering thing does get better if we work at it and don't let it control us. That's a little easier said than done, but the point is that you can be successful even with a stutter.
