Last is the schwa, the most common sound in American English. When you work on the practice paragraph, depending on how fast you speak, how smoothly you make liaisons, how strong your into nation is, how much you relax your sounds, you will find from 50 to 75 schwas. Spelling doesn't help identify it, because it can appear as any one of the vowels, or a combination of them. It is a neutral vowel sound, uh. It is usually in an unstressed syllable, though it can be stressed as well.
