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
This is the output.
