fishaudio/fish-speech is a TTS repository that turns text into speech. The latest release shown on GitHub is v1.5.1. The provided material does not cover what changed in this version. The repository describes generating conversational speech from text and a reference voice, and states that it supports multi-speaker generation, voice cloning, and voice control through natural-language instructions. Python is listed as the repository's primary language.
According to the README, Fish Audio Drama 3 builds scenes with several characters and long dialogues, applies revision instructions over multiple passes, and edits audio. S2-Pro is introduced as supporting fast inference and speech generation in about 100 languages. This shows the repository covers not only single-sentence synthesis but also dialogue scene production and voice control. Installation, weight download, and Docker deployment instructions are included, and the command line, an API server, and the WebUI are documented as inference paths.
However, the feature descriptions are the ones presented in the README, and the provided material contains no independent performance comparison or audio quality evaluation. Only the fact that this is the latest release can be confirmed, and the changes in v1.5.1 cannot be confirmed. The license field also reads NOASSERTION, so the terms of use cannot be stated with certainty. It is therefore difficult to judge the specific release changes, the usage conditions, and the quality of the results from this material alone.
