If any of these factors are true for your situation, you might want to go to therapy one or two times a week for an hour across several months or even a year. In general, many adults who are seeking long-term changes in stuttering will attend twice-weekly therapy anywhere from 6 to 18 months. Hourly therapy charges can range from fifty to eighty-five dollars. Again, these charges will depend on your location and the speech pathologist's hourly charges. Local university speech and hearing clinics often charge less because of their training mission. At many university programs, it is possible to get an evaluation and therapy at lower rates than those listed here.
