voice cloning

Zyphra released ZONOS3-Mini, an Apache 2.0 text-to-speech model with 800M total parameters and 100M active parameters. It clones voices, steers delivery word by word and runs in real time in the browser.

Edge0 released Audio8-TTS-Realistic, a 0.6B open-weight zero-shot voice cloning text-to-speech model under Apache 2.0. It supports 23 languages and adds a final GRPO stage driven by a learned realism critic.

Tencent Hunyuan has open-sourced Hy-SimulMT, a 30B-A3B mixture-of-experts model that translates Chinese and English speech in real time while cloning the speaker's voice. Tencent reports about 3 seconds of StreamLAAL lag on the long-form RealSI benchmark, the lowest among the systems it compared. The weights are listed under Apache 2.0.

Fish Audio has released Drama 3, a text-to-speech model with 35B total parameters and 3B active per token, built for multi-character, long-form audio. It supports up to 16 speakers per text, voice cloning, and streaming. Fish Audio reports first audio in under 100 ms on a single H200.

Microsoft AI released MAI-Transcribe-2-Streaming, a real-time transcription model covering 60 languages with first partial results in just over 100 milliseconds. It also launched two text-to-speech models, MAI-Voice-2.1 and MAI-Voice-2.1-Flash, aimed at voice agents.

AWS published a deployment guide for running Alibaba's Qwen3-TTS-12Hz-1.7B-Base voice cloning model as a real-time SageMaker inference endpoint. The model clones a speaker's voice from a short audio clip and generates speech in 10 languages, including cross-lingual cloning, without retraining.
