Natural UK & US Voice Talent for Text-to-Speech / Conversational AI Project

I'm looking to cast a roster of natural-sounding UK and US voice talent for a text-to-speech (TTS) and conversational AI voice project. I need a diverse range of authentic, believable voices across various age groups and styles - from deep and authoritative to warm, polished, or reassuringly calm. What matters most is that your delivery sounds like a genuine human in a natural, unscripted conversation, so an acting or improv background is a big plus, while theatrical, over-the-top, or cartoonish performances should be avoided. To apply, please submit a proposal with a short, conversational audio sample or a clean clip from your existing reel that showcases your natural speaking voice - a quiet recording space and a decent mic/interface are a must, since a laptop mic or an echoey room won't work for this kind of project - and let me know your specific accent. Selected talent will be secured under a clear, non-exclusive contract that strictly prohibits deepfakes, impersonation, or unauthorised use, ensuring your voice is never used without your prior written consent.
