VOICE ACTING
Crossing the uncanny valley of voice acting
[laughing softly] So, I told my AI to “sound more human,” and it replied [burst of laughter] “define human!” [snorts] I mean, fair point! [chuckling uncontrollably] Then it started judging my spotify playlist [wheezing laugh] Said my taste was… algorithmically tragic. [giggles] Oh no, it even made a PowerPoint about it. [tries to stop laughing but fails] I think I’ve created my own sassier clone.
Multi-lingual
Switch languages and accents with ease
Well, howdy there, partner! Down in Texas, we like our boots dusty and our skies wide open. But switchin’ gears now. Oi mate, fancy a cuppa? London fog’s thicker than gravy out here, innit? See, easy as pie, from cowboy to cobblestone. Oh, but wait ¿Sorpresa? Claro que sí. Puedo hablar español también, con ritmo, con corazón, y con un toque de pasión. Didn’t expect that, did ya? From Houston to Hackney to Madrid,I can go global without missin’ a beat.
Style Prompt: Speak like a Texan, Speak in a cockney accent
MULTI-SPEAKER
Feels like a real conversation
Elena : [whispering shakily] Did you… hear that? Marcus : [soft, eerie tone] Hear what? The house settling? Or the footsteps that stopped when you did? Elena : [voice trembling] Don't joke, Marcus. The air's colder here. I can see my breath. Marcus : [whisper] That's not air, Elena. Look! by the mirror. Elena : [panicked] Oh God… it's smiling back at us. Marcus : Don't move. It only copies what's alive. [evil laughter]

Voices that can win Audie awards
Mr. Jones, of the Manor Farm, had locked the hen-houses for the night, but was too drunk to remember to shut the pop-holes. With the ring of light from his lantern dancing from side to side, he lurched across the yard, kicked off his boots at the back door, drew himself a last glass of beer from the barrel in the scullery, and made his way up to bed, where Mrs. Jones was already snoring.
Style Prompt: Speak in British accent
PROMPT YOUR WAY
Prompt the voices to speak like you want
In the heart of the Serengeti, dawn breaks over a golden horizon. The grass sways gently, kissed by the first light of day. Herds of wildebeest move as one, their hooves drumming softly across the plains. A lioness watches from the shadows, patient, poised. Nearby, a newborn gazelle takes its first trembling steps, a fragile life in a world where survival is written in instinct and silence.
Style Prompt: Narrate this in the calm, authoritative tone of a nature documentary narrator.
