Wyatt Matthew Warner:

• Wyatt: /ˈwaɪ.æt/ (This represents the typical American English pronunciation. Variations exist depending on regional dialects. For example, some might pronounce the 'y' sound more like an 'i' as in 'wit').

• Matthew: /ˈmæθ.juː/ or /ˈmæθ.ju/ (Again, variations exist. The 'th' sound can be slightly different depending on accent, and the final 'u' sound might be shorter or longer).

• Warner: /ˈwɔːrnər/ (The 'a' sound is a broad 'a' as in 'father', and the 'r' sound is a distinct 'r'. Regional variations will affect the exact pronunciation).

Therefore, a detailed phonetic spelling considering potential variations might look like this:

• Wyatt: /ˈwaɪ.æt/, /ˈwɪ.æt/ (to account for pronunciation variations)
• Matthew: /ˈmæθ.juː/, /ˈmæθ.ju/, /ˈmæθ.u/ (to account for pronunciation variations)
• Warner: /ˈwɔːrnər/, /ˈwɑːrnər/ (to account for pronunciation variations in the 'a' sound)
