Often times when English is not a person's first language, the person wishes to reduce the accent from the first language and make it less noticeable. Speech therapy can be effective in reducing the sound of that accent during conversational speech.
a tempo Voice Center offers intervention for this elective approach. It is not necessary to eradicate your original accent, but it might benefit you to learn how to speak English in an English accent in addition to your first language in its proper accent. If you are lucky enough to be bilingual or trilingual, this therapy might benefit you. It can be especially effective if you are misunderstood by listeners because of your accent.
