Voice & POV Integrity
Narrator consistency, perspective clarity, and a credible speaker. Does this sound like one person talking?
What good looks like
A distinct human presence. Word choices, diction, and references that belong to one coherent narrator.
How SongForgeAI scores it
narrator-profile.ts (Build 951) extracts gender / age / relational tuple from the lyrics and flags cross-section contradictions ("my wife + my husband", "I'm 16 + I'm 40").
Common failure mode
POV drift — the speaker sounds like three different people across three verses.
What it looks like in the wild
- Verse 1 and verse 3 clearly spoken by the same person in the same emotional weather.
- Diction that matches the character — a mechanic doesn't quote Rilke.
- The narrator credibly knows what they claim to know.

Imagery Originality
#6Fresh metaphors, defamiliarized objects, governing images that haven't been written to death.
Emotional Truth
#7The ring-test: does it feel true? Earned emotion, unforced vulnerability, no borrowed sentiment.
