Accent reduction has become very popular among foreign professionals who  wish to improve their communication in English. Accent reduction  programs have been around for about twenty five years, but not all  teachers or tutors have the qualifications or experience to help change  their students' English pronunciation.  
One of the keys to  success in any accent reduction program, is to choose the instructor  wisely. Language schools which specialize in teaching ESL (English as a  Second Language), for example, have tried to hire teachers who have  experience with improving accented speech. The demand for accent reduction (also known as accent modification, or “accent improvement”) is high, especially in a challenging economy  where a job may go to another individual who is perceived to have more  clear English speaking skills.  
ESL tutors and teachers have a  range of education and experience. Some ESL tutors have formal schooling  in teaching English as a Second Language, but may have little to no  training in how to technically improve English pronunciation. An ESL  tutor more commonly has strengths in grammar and writing. Some language  schools or companies that provide ESL tutoring, may hire teachers who  have studied in unrelated  fields such as History or Science.     
The  most qualified professional who can provide accent reduction, is the  speech pathologist. A speech pathologist with a Master's degree, has  typically gone through extensive training in anatomy, physiology, the  science of phonetics, phonology, speech science, and has taken a  national exam on human communication.  
Additionally, speech  pathologists who offer accent reduction, have usually attended at least  one 15 hour certification workshop in the area of accent reduction.  The  speech pathologist has typically passed a national exam on  communication.   Some speech pathologists work in hospitals, where they may assist  patients who have suffered from a stroke, brain injury, head trauma, or  some other cause for speech or language impairment. Others have  primarily worked in the public schools with a focus on helping children  with articulation difficulties, stuttering, or other language issue or  delay. The lead accent coach for Advanced Accent Training (AAT) in Atlanta, GA, worked in both the  hospital setting and public schools as a speech-language pathologist for  approximately 20 years, prior to solely focusing on providing  communication skills training for companies and individuals.
The American Speech-Language-Hearing Association has determined  that having a foreign accent is not a “disorder” or “pathology”, so it is  not required that an accent teacher or coach be a speech pathologist.  However, speech pathologists are uniquely qualified to analyze sounds  phonetically and to plan effective programs for many areas of  communication (pronunciation, voice, dialect, and language) change. That  being said, not all speech pathologists have the same  amount or level of experience with accent training. Some speech  pathologists include accent reduction as only a small part of their  practice. While we recommend that an individual who might be interested  in accent coaching, select an instructor who is a speech pathologist,  there is a range of experience among speech pathologists, just as there  is among ESL tutors.
There are a handful of speech pathologists  who have devoted their entire practice to providing accent reduction for  foreign-born professionals, and presentation and regional dialect  coaching for native English speakers. Advanced Accent Training (AAT) is  one of the businesses that has devoted full time efforts to assist  companies and individuals to improve their English pronunciation for  work and social success.  The lead accent instructor for Advanced Accent  Training, Jon Berton, M.A.-SLP, is  speech pathologist  with over 25 years of experience. He has been trained and certified in  three accent reduction methods, as well as several dialect coaching  programs. Jon studied with the late dialect coach, Sam Chwat, who you  may know as the dialect coach to the stars. Jon started his career  as an ESL teacher in Japan. He majored in psychology and linguistics  while attending the Year in Japan program at the University of Southern  California. 
Jon also taught ESL to Japanese business people and was the lead  ESL teacher at Asian Rehabilitation Services in Los Angeles, while  completing his Masters degree in Communication. Jon has  worked as a clinical speech pathologist, as an ESL teacher, and during  the last fifteen years as a lead accent trainer with 100% focus on  helping his clients to achieve their communication goals. Jon’s unique  combined experience  has made him one of the most sought after accent  and speech consultants around the United States. 
There  has been a resurgence of interest in accent reduction classes since they  first started being offered in the late eighties and nineties. The  wavering economy here in the United States and around the world has led  to more and more professionals wanting to improve their communication  skills. Competition is more fierce for higher paying jobs, so any  advantage can potentially increase the chances of being hired. Accent training is offered as an online accent class, making it even easier for the busy professional to fine tune his/her  speech skills, without having to battle traffic after work. Accent  lessons can be taken from the comfort of one’s own home on weekdays or  weekends. Yet, some things have not changed. Choosing the most qualified  and experienced teacher remains one of the most important ways to  maximize successful communication in the new year.
