To be fair, it's to help. I stutter due to genetics and improved it by singing and speaking to myself and others on words that's difficult, I'm not 100% fluent and it could just be placebo, but I usually reference a scientific paper that backs up singing as a means to repair and activate neural plasticity for speaking(after brain injury to be specific).
