Fish Audio Launches Full-Duplex Voice Model Live 3

On November 11, Fish Audio released Live 3, a full-duplex real-time speech model, along with a companion voice agent platform, targeting customer service and call-center voice agents that "sound human, converse naturally, and get things done."

Confirmed

• Core capability: the model can listen while speaking, naturally produce backchannel cues like "mm-hmm," and know when to stay quiet instead of talking over the user—solving the dead loop common in traditional AI customer-service voice agents that can't hear clearly and keep asking users to repeat themselves
• According to @testingcatalog, Live 3 can distinguish simple acknowledgments from genuine interruptions: it keeps talking when the other party says "yeah" mid-reply, but stops when it hears "wait, actually"
• @aliscodes tested it: when reading out a phone number with pauses, the model wasn't interrupted by the pauses or forced to ask for a repeat, unlike traditional half-duplex voice AI
• Platform capabilities: supports inbound/outbound calls and in-app/web conversations; agents can listen to calls in any language (@drcintas)
• In the demo, users only needed to describe their needs in a single sentence, and Fish Audio Agent generated an incoming-call assistant in about 5.5 seconds

Why it matters

Full-duplex real-time listening and speaking is a key threshold for making voice agents feel human. Live 3's handling of backchannels, interruptions, and silence timing directly targets the most criticized pain points of today's phone-based AI customer service. If it holds up in real-world use, it could meaningfully improve the usability of voice customer service and calling scenarios.
