Fish Audio Raises $52M in Seed Funding After Turning Passion Project Into One of Voice AI's Fastest-Growing Companies

Fish Audio, an innovative AI voice platform specializing in expressive real-time text-to-speech, voice cloning, and voice agents, has successfully secured $52 million in seed funding. The funding round, which took place on July 28, 2026, was led by Coreline Ventures and Capital Today, with additional participation from 359 Capital, Play Time, HF0, 645 Ventures, Parable, Carya Venture Partners, and Alphalist Partners. This financial backing comes as Fish Audio celebrates its first anniversary, during which it has achieved remarkable growth, reaching an annual recurring revenue (ARR) of $21 million and attracting over 8 million users.

Founded by Shijia Liao, a former NVIDIA researcher, Fish Audio began as a side project aimed at improving the quality of synthetic voices, which Liao found lacking. The initial open-source project, Fish Speech, quickly gained traction on GitHub, becoming one of the most popular voice projects with over 31,000 stars. The platform's rapid ascent in the voice AI sector is attributed to its ability to clone voices from just a five-second audio clip in approximately 15 seconds, supporting more than 83 languages and offering word-level emotion control through over 15,000 natural language controls.

The recent funding will be pivotal for Fish Audio as it aims to expand its model lineup beyond text-to-speech capabilities to encompass the full audio-native stack, including voice-native large language models (LLMs) and speech-to-speech technologies. Additionally, the company plans to bolster its enterprise sales team and enhance developer tooling and integrations with partners such as LiveKit and Retell. This strategic approach aligns with the growing demand for advanced voice AI solutions across various sectors, including gaming, content creation, and enterprise applications.

Fish Audio's competitive edge lies not only in its technological advancements but also in its commitment to accessibility. The company provides high-quality, human-sounding voice AI solutions that cater to a wide range of users, from independent creators to large enterprises. Its recent model, S2.1 Pro, has been favored by nearly 67% of listeners in blind tests compared to leading competitors, highlighting the platform's superior performance and user satisfaction.

The broader implications of this funding round underscore the increasing importance of voice technology as a primary interface for artificial intelligence. As businesses across industries seek to enhance user engagement and streamline communication, Fish Audio is well-positioned to capitalize on this trend. The company's innovative approach and strong market traction suggest it will continue to lead the way in the evolving voice AI landscape, making significant contributions to the future of human-computer interaction.
