How They're Made: Sigma Lenses

Audiio Voices is a new AI-driven voiceover tool that transforms voice recordings into professional voiceovers while preserving emotion and authenticity. With advanced voice-to-voice technology powered by Eleven Labs, users can upload their own audio and convert it into the voice of their choice, all while preserving the natural tone, inflection, and rhythm of the original performance.

Voices can really help assist creators who don't typically have access to voiceover talent but it's just as valuable for those who are looking to narrow a search down when looking for talent.

Voices is only available as part of a Pro+ Plan, and PetaPixel viewers can get 40% off the first year of the Pro+ Plan, bringing the price down to just $18/month — billed annually. Visit http://audiio.com/petapixel and use code VOICES40 at checkout to get the deal. Hurry, this offer is only available for a limited time!
