I want to use speech_recognition to transcribe speech from radio (FM, AM, FSK,...)

Pirates speech to text
Collect radio sounds
An attempt to collect radio sounds depending on what text accompanies them, on time, on frequencies or other factors. For example every time the software listens to streaming and recognizes a sound of voice (300 and 3000 Hz) or a word then it records down/collects.
