RealtimeSTT is an open-source speech recognition model capable of converting spoken language into text in real time. It employs advanced voice activity detection technology to automatically detect the start and end of speech without manual intervention. Additionally, it supports wake word activation, allowing users to initiate speech recognition by saying specific wake words. The model is characterized by low latency and high efficiency, making it suitable for real-time transcription applications such as voice assistants and meeting notes. It is developed in Python, easy to integrate and use, and is open-source on GitHub, with an active community that continuously provides updates and improvements.
