audio generation

Google DeepMind has released Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, text-to-speech models that generate custom voices from natural language prompts and support line-by-line performance direction. The models top Hume AI's Voice Design Benchmark at 71.4 and claim first and second place on its Overall Quality Index.

MiniMax has published MiniMax-H3, a 33-billion-parameter omni-modal generative model capable of producing up to 15 seconds of 2K video with native stereo audio. The model accepts text, image, video, and audio inputs, though its full 2K pipeline depends on a hosted preprocessing component not included in the open-source release.

Stability AI has released Stable Audio 3 Medium, a 2 billion parameter latent diffusion model capable of generating variable-length audio up to 380 seconds. The model generates music and sound effects in less than 2 seconds on an H200 GPU, trained on 1.28 million licensed and Creative Commons audio recordings.
