MINOR
The bill was revised to streamline its purpose by removing a redundant reference to defining terms, as those definitions are now included later in the text. Additionally, a new clause was added to the definition of a voice depiction, clarifying that the altered sound must be nearly indistinguishable from the original voice and convincing enough for a reasonable person to believe it is genuine.
Scope change
The bill's scope remains focused on protecting voice likenesses, but the definition of what constitutes a protected voice depiction has been expanded to include a 'reasonable person' standard for authenticity.
DEFINITION

Removed the phrase 'AND PROVIDING DEFINITIONS' from the bill's title summary because the definitions section is now explicitly included in the text.

Added a requirement that a synthetic voice depiction must be 'nearly indistinguishable' from the real voice and convincing enough that a reasonable person would believe it is genuine.
