I disagree. While working a crappy fast food job as a stuttering teen, I built up my confidence and started working the drive-thru window for an hour or so on a few random shifts. I developed a funny cheezy radio announcer voice and used that to not stutter while speaking through the intercom. I was very successful at this and this built my confidence up further. One of the regulars kept hearing my on the drive-thru intercom and she invited me to apply for a dispatcher job, which was 100% answering the phone and speaking on the radio. By this time I had built up my confidence and stuttering management techniques so I gave it a shot. And even though I stuttered a bit through my interview and on my first few days on the job, I stuck with it. It turned into a career in senior management and global IT consulting. All because I choose to take a chance and apply for a 100% speaking job despite my stutter. It's worth taking a shot on.
