Scripts Usage

As any python script any of these tree scripts (.py files) can be run with the following command: python script_name.py parameter1, parameter2 ....

Every script has two parameters:

• first (required) - name of the .wav file to recognize
• second (optional) - name of the text file to write recognized text. If not specified, uses first_parameter.txt

Examples:

• python script_online_sr.py audio.wav (writes text in audio.txt)
• python script_online_sr.py audio.wav audio_outout.txt
• python script_vosk.py 'sounds\filename.wav' (recognize current_folder\sounds\filename.wav)
• python script_offline_sr.py 'D:\sounds\filename.wav'
