This is one way to do Audio to Text Conversion / Transcription on your PC and not in the cloud.
I found these steps at: https://medium.com/illumination/how-to-transcribe-audio-to-text-using-audacity-for-free-f027b4a5a240
Start by installing Audacity. https://www.audacityteam.org/
Then you need to install an Audacity AI plugin. https://github.com/intel/openvino-plugins-ai-audacity/releases/
To enable the plugin, go to Preferences > Modules and enable mod-openvino.
Import the audio you want to transcribe into Audacity. Highlight and select the full audio.
Then choose Effect > OpenVINO AI Effects > OpenVINO Whisper Transcription
Once it is complete, then export the text via File > Export Other > Export Labels
There will be timestamps. They can be easily removed using my Rubber Band Text Editor. https://vpelss.github.io/RubberbandTextEditor/
Note that you can run Whisper from the command prompt, but it is a bit of a slog… https://github.com/ggml-org/whisper.cpp and https://github.com/ggml-org/whisper.cpp/releases
