If you want to practice your American English pronunciation skills on your own, then this site may be just the answer!  The site offers videos, descriptions and audio files so you can see, read and listen to how to make different vowel and consonant sounds.  It also offers lessons and gives information on how use stress, rhythm and intonation within words and sentences.  These skills are also very important to know, since these make up the “music” of the language and significantly help listeners understand you when you speak in English.  I hope you find this site useful!
