OpenWhisper

OpenWhisper is an open-source voice-to-text application designed to run entirely on your local computer. It converts spoken audio into accurate, searchable text using advanced speech recognition models, without sending data to external servers. The primary purpose of OpenWhisper is to provide a private, offline transcription solution for users who need reliable speech-to-text capabilities while maintaining full control over their data.

Powered by OpenAI Whisper and NVIDIA Parakeet, OpenWhisper supports high-quality transcription across multiple languages and accents. Because it works offline, it is suitable for environments with limited or no internet connectivity, as well as for privacy-sensitive workflows. The tool is free to use and can take advantage of your system’s CPU and GPU to accelerate processing, making it practical for both short clips and longer recordings. Its open-source nature allows developers to inspect the code, extend functionality, and integrate the engine into custom applications or automation pipelines.
