Article Summary
The release of Gemini 3.1 Flash TTS marks a significant upgrade in synthetic voice capability, giving developers fine-grained control over AI speech generation. Key new features include the use of audio tags—intuitive natural language commands embedded in the text—to dictate vocal style, pace, and delivery with precision. The model maintains its ability to support over 70 languages while enhancing quality, evidenced by a high Elo score on industry benchmarks. Crucially, all generated audio is watermarked with SynthID, providing a verifiable mechanism to prevent the spread of deepfakes and misinformation. This advanced set of tools empowers developers to build highly immersive and controllable conversational AI experiences across platforms like Google AI Studio and Vertex AI.Key Points
- The introduction of audio tags allows developers to control speech output with granular detail, enabling natural language direction of vocal style, pace, and delivery.
- Gemini 3.1 Flash TTS improves overall speech quality and performance across 70+ languages, establishing a new benchmark for expressivity and naturalness.
- All generated audio is watermarked with SynthID, a critical safeguard mechanism designed to combat deepfakes and maintain media provenance.
