ha-ya-i, three beats — spelled identically in romaji to 速い "fast," and pronounced the same way.
hayai
Three beats of matching size. This word is a true homophone of 速い in ordinary speech — same morae, same rhythm — and the kanji is what tells them apart on the page. In conversation the context does the work, which is a reminder that Japanese tolerates far more homophony than English does.

今日は早く帰ります uses the adverbial 早く, where the final u devoices before the k of 帰ります. 今日 at the head is two morae with a long o. So the sentence opens with a held vowel and continues with a whispered one, both easy to lose.
"ha-YAI" fuses the second and third morae into an English diphthong and stresses them, dropping the word to two beats. Separate them with a deliberate pulse. And keep the h light — English speakers push far more air through it, which makes a neutral adverb sound like an exclamation.
