The word "woulda" is often used as a contraction of "would have." In IPA phonetic transcription, it would be spelled /wʊdə/. The first sound is the "w" sound, followed by the short "u" sound. The "d" sound comes next, followed by the schwa sound, which is a very short and weak vowel sound. Finally, the word ends with another short "a" sound. While this contraction is commonly used in informal speech, it is important to use the correct spelling and grammar when writing formally.
