Failure to create model

My pre-trained en-us model downloaded from the vosk website keeps failing to build. It was working and building perfectly fine with the same model, I am not sure what to change.

This is my code.


from vosk import Model, KaldiRecognizer
import wave
import json

def transcribe(file_path): model = Model('src/vosk-model-en-us-0.22') recognizer = KaldiRecognizer(model, 16000) # includes the path to the audiofile and the bitrate

file = wave.open(file_path, "rb")

transcribed_text_list = []

while True:
    data = file.readframes(4000)
    if len(data) == 0:
        break
    if recognizer.AcceptWaveform(data):
        result = json.loads(recognizer.Result())
        transcribed_text_list.append(result['text'])

final_result = json.loads(recognizer.FinalResult())
transcribed_text_list.append(final_result['text'])

complete_text = ' '.join(transcribed_text_list)

return complete_text
