    ❗ Project Status: Community-Driven

    This project is no longer being actively maintained by me due to time constraints. I've taken on too many projects and I have to step back. I will no longer be implementing new features or providing user support.

    I will continue to review and merge high-quality, well-written Pull Requests from the community from time to time. Your contributions are welcome and appreciated!

    RealtimeSTT listens to the microphone and transcribes voice into text.

    Hint: Check out Linguflex, the original project from which RealtimeSTT is spun off. It lets you control your environment by speaking and is one of the most capable and sophisticated open-source assistants currently available.
