Alternatives to Whisper
OpenAI's open source speech recognition
Whisper ranks #8 of 8 in Transcription tools, with an Alt Score of 55. It is licensed under MIT, free and available on Windows, macOS and Linux. 10 of 10 checklist rows are verified against a public source.
Developers and researchers who need to add speech-to-text transcription or translation to an application, or who want to run automatic speech recognition locally without a hosted API.
An open-source, general-purpose speech recognition model trained on 680,000 hours of multilingual and multitask supervised audio data. It transcribes speech in many languages and can translate that speech into English text. Whisper is released as pretrained checkpoints in multiple sizes (tiny through large), letting users trade off speed, resource usage, and accuracy, along with the training/inference code.
Install the Python package (with ffmpeg) and run the `whisper` command-line tool on an audio file, or call the Python API directly, choosing a model size; Whisper's encoder-decoder Transformer then outputs a transcript or English translation, optionally with timestamps.
