Round your lips into a tight circle. Lift the back of your tongue toward the soft palate and add voice.

Americans pronounce wishes as WIH-shuhz (/ˈwɪʃəz/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "I wanted to express my warmest wishes on this joyous occasion".
Record yourself saying "wishes" and play it back. The mic stays on your device — nothing's uploaded.
2 syllables, 5 sounds. Tap a syllable to jump to its row, then explore each sound's mouth shape and how it's made.
The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch WIH — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
