Step 1 - (Try Step 1, then return to this syllable page using the page back on the top left)
Find the placement and rhythm accent Speak simultaneously with this short clip. Simply put on headphones so you can hear the speakers voice & not your own as you speak with the text. Note the jaw aperture, tension in the tongue and lips and the relative length of the syllables.
Your conclusion? There is a distinctly frontal placement in the British accent, with a lot of tension and use of the lips and front facial muscles. You will find that to keep in pace with the native speaker the sounds and speech will feel 'penned in' to a certain area in the mouth and that you need to "stretch" some syllables and reduce others. English is a stress timed language, whereby native speakers only stress certain syllables, and as Swedish is a stress timed accent as well, this makes the rhythm and intonation more similar to English than some other non native languages, though subtle rhythmic differences still need to be addressed.
Step 2 - Ear train with the phonetic sounds of the British Accent. Test and record yourself
Step 8 -Test again with monologues, and if not satisfied, repeat above steps.
