Gemini 2.5 pushes the boundaries of AI-powered audio by introducing real-time, expressive voice interaction and advanced text-to-speech (TTS) generation, all handled natively within the model itself.
Immersive Real-Time Conversations with AI
Gemini 2.5 is designed to understand and produce high-quality speech, mimicking the richness of human dialogue. It interprets tone, rhythm, and emotional cues, making interactions more natural and responsive. With near-zero latency, conversations with AI feel fluid and remarkably human-like.
Key Features of Native Audio Dialog:
- Expressive Speech: Gemini adapts its speech for tone, rhythm, and style, offering more lifelike interactions.
- Custom Style Control: Users can prompt the model with natural language to switch accents, whisper, or adopt specific tones mid-conversation.
- Tool Integration: Gemini can access tools or fetch real-time data during conversation, enhancing its utility as a smart AI assistant.
- Context Awareness: The system intelligently filters background noises and irrelevant chatter, responding only when appropriate.
- Audio-Video Sync: Gemini can interpret and discuss ongoing video or screen-sharing content in real time.
- Multilingual Support: Converse in over 24 languages, with seamless code-switching between multiple languages in a single phrase.
- Affective Dialog: The model detects the speaker’s emotional tone, making responses more empathetic and context-aware.
- Advanced Reasoning: Deep reasoning enhances the depth and coherence of responses, especially in complex discussions.
Next-Level Text-to-Speech Capabilities
Gemini 2.5 also redefines TTS by offering fine-grained control over how audio is generated. From emotional storytelling to formal news reading, the output can be tailored for any scenario using simple prompts.
Highlights of Controllable TTS:
- Dynamic Audio Performance: Generate emotionally rich audio for poetry, podcasts, or complex narratives.
- Pace and Pronunciation Control: Users can adjust speed and pronunciation accuracy for clarity and tone.
- Multi-Speaker Dialogues: Create engaging two-person conversations from plain text, ideal for summaries or educational content.
- Language Versatility: Produce high-quality audio in more than two dozen languages with native fluency.
Developer Access and Tools
For developers, Gemini 2.5 opens new doors for innovation. Native audio features are now available via the Gemini API in Google AI Studio and Vertex AI. Developers can experiment with real-time dialog using the live stream tab, or generate custom speech in the media tab.
Prioritizing Safety and Transparency
Google has implemented comprehensive safety protocols for Gemini’s new audio features. Risk assessments, internal and external evaluations, and rigorous red teaming have guided the responsible rollout. All AI-generated audio is marked with SynthID, a watermarking technology to help identify synthetic content and ensure transparency.
