Thanks mmasny.
Well in general,I don't speak clear.I been In Uk too long and now I want to speak more clear to improve my English.I would like the most commune tongue tip when we speak English( where to put the tongue when I speak,the only one I know is ""TH""
As I Am Portuguese the world are different in some way.
There are only around 6 or 7 consonants in English that don't exist in Portuguese phonology:
/θ/
thin
/ð/
then
/w/
we
/ɹ/
run
/j/
yes
/ŋ/ ba
ng
/h/
hit
So, I think saying the only one you know is 'th' is nonsense. You know the rest (at least 15) and if you know affricates ('
chair', 'mea
sure') then at least 17 others.
It is far more likely to be a problem with your vowels as very little clarity of speech is achieved through consonants - they are omitted, altered, adapted and no clarity is lost. Vowels are much more important in intelligibility, and also much more difficult to describe. The best way to do it is to imitate.
Portuguese has similar vowels to English, indeed the vowel system in Portuguese is much richer than in English. Also, European Portuguese (if that is what you speak) is a stress-timed language and so is English. This means that the time between two stressed syllables is roughly equal and results in a language that has lots of sounds that are almost non-existant.
If you want to get a feel for the difference between a stress-timed language to it's counterpart - a syllable-times languaged; where the duration between all syllables is roughly equal - then compare European Portuguese (stress-timed) with Brazilian Portuguese (syllable-timed). You will notice that Brazilian Portuguese sounds more enunciated, or clear like most other Romance languages. Whereas European Portuguese tends to have stressed and unstressed forms for things such as articles and sounds more like English, German, Swedish or similar in it's clarity.
