If you have a publication that comes with good farm vocabulary, but no tape, have a native speaker from the target country tape it for you. Or perhaps you have some words and expressions you want translated. These homemade tapes will help you maximize the time you spend with your tutor. I have learned that it does not hurt to ask, and most people will be more than glad to help. You may want to check with several persons to make sure the translation is correct before you have it taped.
Vowels are often the major expression of an accent.
When words are sung, vowels are drawn out so their major pronunciation points are emphasized. There are specific songs that help people improve their accents. Try overly exaggerating the sound as if you were imitating a motorcycle engine and do not expect to be successful right away. Listening to short wave broadcasts in Spanish, or local Spanish radio stations and television are a great help. The advantage of television is that one can catch body language and facial expressions and can capture the context of what is being said a little better.
