Youdospeak Phonetic Spelling is based on the way vowels sound in commonly spelled words called ‘Word Families’.
For example, because words commonly spelled with /aw/ like,
law saw raw
[l/aw] [s/aw] [r/aw]
have the same sound as words spelled with the short /o/ like,
got hot a lot
[gaw/t] [haw/t] [uh/law/t]
the short /o/ is represented by [aw] on the Vowel Chart.
Word Families are also used to teach English-speaking children to read and write. (See: Common Word Families)
