Suno mishears lyrics the same way a person would: dense lines, odd spellings, and tongue-twisters get garbled. The fix is writing lyrics that are easy to sing, not just easy to read.
1. Simplify the problem line. Play the bad take and write down exactly what it sang. Nine times out of ten, one or two words are the culprits — unusual spellings, homophones (right/write), or consonant clusters. Rewrite just those words simply.
2. Break up dense lines. If a line has 14 syllables at 140 BPM, Suno will drop or merge words. Split it into two shorter lines. The lyric still says the same thing; it just gives the singer room.
3. Punctuate. Commas and periods tell the vocal where one thought ends. Run-on lyrics with no punctuation are where misheard words breed.
4. Avoid homophones in exposed spots. 'Right,' 'write,' 'rite' all sound identical — Suno picks one. In a chorus hook, use words with only one possible hearing.
5. If one word keeps failing, respell it phonetically (see the 'Majesty' → MAD-jest-ee trick) or swap in a synonym. Don't burn ten generations on one stubborn word.
