I (24) actually work for a huge financial firm on the phones. I’m new to this thread but I assume it’s common to only stutter in your “regular voice” not singing or yelling etc; I think I can do the phones role because I have an entire customer service personality that switches on… still can’t do drive thrus. I stuttered at my first cashiering job at first, didn’t stutter at a photography phone call job, and don’t stutter at this phone job.
