How do you keep a character's voice the same across shots?

Without Higgsfield: Choose one voice source once, a preset or a cloned voice, and have every generation pull from it with the delivery and tone kept fixed, since switching sources mid-project is where consistency breaks first. Seedance 2.5 locks a character's voice along with its look from the character sheet, and for Hailuo 3.0 a clean audio clip of the voice gives the model something to hold.

Axis: let the model derive the voice from the character sheet … lock a chosen voice and reuse it

Concept: character sheet
