Get Rid of your Accent, General American
This book helps with clarity of speech. In this speech training manual, we teach all General American English sounds, and each chapter in the book covers one sound. The book is ideal to use with its Audible edition or with the app, American Accent Toolkit.
"Highly recommend to everyone willing to enhance his pronounciation. Exercises included in the books are fun and incredibly effective. After one month of training I barely can recognise my own speech. Many thanks to the authors!" Dawid Jachwak, Amazon customer
