using this stuff for a newbie

hello, i'm new to speech recognition, vosx and python, but i want to translate speech from a simple video i downloaded from the internet (and later even tts'ing to my language or even speech to speech).
i have tried the listen_in_background function in the example with google engine and it works although i'm not able to obtain my goal (word by word translation)

with your software, the recognize_vosx in the callback keeps giving me the same result "Please download the model etc..." and i have done it and unzipped in vosk/model/it (i'm italian) but I can't get it to work.

so i have python3.12 installed, pyaudio, speech_recognition, and my ide for now is the simple IDLE, can you please give me a simple source to begin with this stuff?
