    RT @MTSlive: AssemblyAI CEO @YouveGotFox reveals how just 10 seconds of audio is enough to clone someone's voice with AI: "We have over 4,000 voices available on our API, and we also support instant voice cloning. With as little as 10 seconds of someone’s voice, you can instantly clone it. Obviously, if you have the consent to do that." "The voice for your AI, in a lot of ways, that is the user experience. I might want my voice to sound funny and sarcastic because that fits my brand." "If you’re calling into a business, you want it to sound local. If you’re in a town in the UK, you want it to have the same regional accent as where you’re living." @AssemblyAI

    Speed matters for voice agents, and open models are the fastest in the run on short transcripts: on 30-second and 2-minute inputs the fastest answer in under a second (median). Every failure counts against the quality score too: wrong format, refusal, timeout, error.
