Gemini 3.1 Flash Live: Making audio AI more natural and reliable
Google DeepMind has shipped an upgrade to Gemini 3.1 Flash Live, the voice AI layer that powers real-time conversations across the Gemini ecosystem, with a focus on the problems that have made audio AI painful to use in practice: background noise, conversational context drift, and the uncanny tendency of AI voices to sound like they are reading a script.
On ComplexFuncBench Audio, a benchmark that tests multi-step function calling under real-world constraints, Gemini 3.1 Flash Live scored 90.8 percent, ahead of the previous model, according to the DeepMind blog post announcing the release on March 26, 2026. The model can now track a conversation thread for twice as long as before, keeping context intact through longer exchanges without losing the thread.
On Scale AI Audio MultiChallenge benchmark, which tests how well models handle complex tasks in audio form, the model reached 36.1 percent with thinking enabled. On Scale AI Voice Showdown, a broader real-world evaluation of voice AI systems, Google current Gemini 3 Pro and Gemini 3 Flash are statistically tied at the top of the Dictate leaderboard with an Elo score around 1043 to 1044, with GPT-4o Audio trailing, according to VentureBeat coverage of the benchmark results.
The practical test is what happens when someone talks over background noise, interrupts, or wanders across three topics mid-sentence. The DeepMind team, led on the blog post by Valeria Wu, a product manager, and Yifan Ding, a software engineer, frames the improvement as natural and reliable, which is exactly the gap that has made voice AI feel like a demo feature rather than a production tool. Three companies have given positive feedback on the model in their workflows: Verizon, LiveKit, and The Home Depot. LiveKit involvement is notable, the company builds the real-time voice AI infrastructure that developers actually use, not just a reference deployment.
Google is also watermarking all audio output from 3.1 Flash Live with SynthID, its detection tool for AI-generated content, addressing a concern that grows with every voice AI release. The model is based on Gemini 3 Pro with a 128K input context window and 64K output. With this launch, Search Live in Gemini Live is now available in more than 200 countries and territories, the company said.
The benchmarks are what they are. What matters is whether the model actually holds up when someone talks over a dishwasher, interrupts mid-sentence, or circles back to an earlier point three turns later. The feedback cohort, a real-time audio infrastructure company, a retailer, a telecom, suggests Google is pushing into deployment, not just evaluation.
Voice AI has spent two years as a benchmark star and a production disappointment. Whether this closes that gap is the only number that matters.
