Japanese · Pronunciation Guide
sa-mu-i, three beats — the u is unrounded and the final i is a beat of its own.
samui
The mirror of 暑い in shape as well as sense: three even beats, this time with the crest on mu. This is the mirror image of 暑い in both meaning and shape: same number of beats, same bare final i, different middle. Drilling the pair together makes both rhythms stick.

今日は寒いですね closes with ですね, a devoiced su plus a short ね — and the pitch on that final particle does the work of the English tag "isn't it?" The rest of the sentence has no length in it at all, so the whole line is short, even beats with one whispered vowel near the end.
"sa-MOO-ee" rounds the u, stresses it, and stretches the final vowel. Flatten the lips — check in a mirror that they don't push forward after the m — level the three beats, and cut the closing i short. Learners often treat adjective-final i as an emphatic ending; it's just a mora like any other.
