TTSFM is an open-source text-to-speech client that mirrors OpenAI’s TTS service, offering a free and compatible interface. The latest v3.4 version brings several important updates: optimized speed and built-in audio format conversion; the product has been split into two variants – a full version with built-in ffmpeg support for automatic long text merging and format conversion, and a lite version that retains core functions for users with limited resources. This project provides developers and researchers with a free OpenAI TTS alternative, suitable for integration into personal projects for development and testing. The author mentions this is their first long-term maintained open-source project, and while thanking the community for their support, they are also holding a giveaway event to give back to users. For developers and enthusiasts in the AI speech synthesis field, TTSFM offers a practical and economical choice.
