  Privacy is a hot topic for policymakers across the globe, including the
United States. Evolving advances in AI and emerging concerns about the misuse
of personal data have pushed policymakers to draft legislation on trustworthy
AI and privacy protection for its citizens. This paper presents the state of
the privacy legislation at the U.S. Congress and outlines how voice data is
considered as part of the legislation definition. This paper also reviews
additional privacy protection for children. This paper presents a holistic
review of enacted and proposed privacy laws, and consideration for voice data,
including guidelines for processing children's data, in those laws across the
fifty U.S. states. As a groundbreaking alternative to actual human data,
ethically generated synthetic data allows much flexibility to keep AI
innovation in progress. Given the consideration of synthetic data in AI
legislation by policymakers to be relatively new, as compared to that of
privacy laws, this paper reviews regulatory considerations for synthetic data.
