Slide 1 of 4
Real-time action
Agents can use tools and retrieve real-time information from sources like Google Search, or even custom developer-built apps, making conversations more useful.
Proactive listening
Knows the difference between direct engagement and background chatter. Understands the rhythm of speech, knowing precisely when to talk – and when to stay silent.
Consistent responses
Maintains specific personas and follows directions during long interactions. Even in complex, winding conversations, the model stays on track – and in character.
Alphanumeric accuracy
Handles complex alphanumeric data – like flight codes or pricing – reliably and accurately.
Live speech translation
Uses Gemini’s speech-to-speech translation capabilities to break down language barriers.
Broad language coverage
Delivers fluid speech-to-speech translation across 70+ languages and 2,000 language pairs, dissolving communication barriers in real-time.
Consistent intonation
Preserves the original speaker’s intonation, pacing and pitch, to convey not just what’s said, but how it’s said.
Multilingual input
Understands multiple languages in a single session, to help you follow multilingual conversations without changing any settings.
Automatic language detection
Identifies the language being spoken and starts translating – so you don’t need to figure it out yourself.
Noise robustness
Filters out ambient noise so you can hold conversations comfortably, even in loud outdoor environments.

Integrating Google Gemini’s 3.1 audio models has improved The Home Depot’s contact center experience. This conversational AI enables natural, intuitive dialogue, moving away from rigid scripts to foster deeper engagement. The platform accurately captures complex details—like alphanumeric product codes—even in noisy environments. And real-time translations allow our customers to switch languages seamlessly, making our "orange-apron" expertise more accessible and scalable than ever.
Using Gemini 3.1 Flash Live in our Miri AI makeup and outfit assistant has noticeably raised the bar for real-time conversational interactions — instruction adherence in long 20+ turn sessions improved by ~25% over 2.5 Flash, and tool calls for memory recall and structured entry executed reliably in our tests. Voice responses feel significantly more natural, with clearer sentence-level intonation and stable persona performance, making a real difference in how users engage with the app.
The biggest win with the new Gemini 3.1 audio model is consistency over time. Longer sessions stay on-persona with far less speaker drift, and the experience feels both more natural and more dependable for production-style voice agents.
Google's Audio-to-Audio capability moved the sound of our Virtual Agents to more natural sounding agents. It enabled us to have more control of its pitch and intonation. And just moving to Audio-to-Audio removes the huge latency we experience when the Virtual Agents have plenty to convey back to the customers. Planning ahead, we've seen the preview of the Gemini 3.1 voice model, and this would just further improve the experience, towards a more natural conversation that Verizon is striving for.
YouTube is transforming its contact center operations by deploying Google’s Gemini CX Agent Studio. Leveraging the Gemini 3.1 Flash Live native audio model, the platform now delivers ultra-low latency and natural voice interactions, delivering positive customer engagement and significantly increasing support capacity. This AI-driven evolution enhances the entire lifecycle—from acquisition to retention—by ensuring rapid, high-quality resolutions. Notably, during high-demand events like NFL Sunday Ticket, viewers now receive near-instantaneous support through kickoff, proving that YouTube can deliver reliable, top-tier service at any scale.
Performance
Our live dialogue models can be used to build powerful, low-latency voice applications, capable of complex reasoning. High-performance, reliable deployment.

Audio MultiChallenge
This multi-turn benchmark assesses the conversational proficiency of audio-language models and spoken dialogue systems, including speech-to-speech variants. It evaluates their capacity to follow instructions, maintain self-consistency, integrate previous context, and manage natural speech corrections throughout long-form dialogues.
Original text prompts were converted to audio and then function calling accuracy was evaluated according to original benchmark methodology.

ComplexFuncBench Audio
This static context multi-turn benchmark measures the model's ability to perform a sequence of interdependent function calls related to travel booking. Since this was originally a text-to-text evaluation, we synthesized audio for each prompt. Then used the published scoring apparatus to evaluate the performance of the Gemini realtime API. More details on ComplexFuncBench can be found here.

Big Bench Audio
This single turn benchmark consists of 1,000 audio recordings that pair an audio clip (ranging from speech to natural sounds) with a text question. It measures five diverse audio comprehension skills: audio captioning, speech understanding, audio scene understanding, accent/language identification, and sound recognition.
