Fish Audio · Directable TTS

Fish Audio Drama 3

Fish Audio's new flagship speech model, launched 13 October and following Fish Audio S2 (covered in week 11), built for directed performance. Delivery notes go in square brackets inside the script, seven paired tags (whisper, emphasis, soft, fast, slow, stress, forceful) change only the words they wrap, and multi-speaker scenes generate in one pass. Fish Audio reports 93.2% on Artificial Analysis' Pronunciation Robustness benchmark, first at launch, against 88.1% for its S2.1 Pro, self-reported. It runs on fish.audio, the mobile apps and the API, and open weights are on Hugging Face, free for commercial use below US$500,000 in annual revenue. Technical report arXiv 2610.18010.
