Yes. Look for a attorney that specializing in ADA and does free consultations; should not be hard to find. From the quick description you gave she said it was because of your stutter. And she equated lack of confidence because of your stutter to do. I'm positive you would not have applied for the job unless you thought you could speak on the phone; not some person applying for job just to sue (like a guy applying for a Hooters waitress).
