Are you interested in reducing your accent? In this video you will find some useful pieces of advice from Paddy Kennedy, principal of Kennedy Communication Studio, such as:

-Your accent is not the problem
-Language has rhythm
-Hear the music in the language
-You're trying to speak my language in the rhythm pattern of your language and I can't understand it.
-English is a beat-driven language... everything we say can be drummed out.
-We speak in sound units: We-do-not-speak-word-by-word
-You don't want to "see the language"... you need to hear it, to listen to it.
-Imitate native speakers, everything they say... and exaggerate, make the sound big!!.
-You need to train the organs of articulation: your tongue, your cheeks, your mouth (that's why no chewing gum is allowed in class!)
-Tongue twisters: find them and say them as if they mean something... and say them with rhythm.
-The most important thing is the up and down of the language.
-Just keep practising... that's how we learnt our mother tongue.
