vosk 0.3.37 Do I need to deal with this WARNING ?

How to reproduce them?

[zxl777]

audio: https://transfer.sh/Oax5b2/temp.wav

model: https://alphacephei.com/vosk/models/vosk-model-en-us-0.22.zip

        wf = wave.open(f"temp.wav", "rb")
        if (
            wf.getnchannels() != 1
            or wf.getsampwidth() != 2
            or wf.getcomptype() != "NONE"
        ):
            print("Audio file must be WAV format mono PCM.")
            exit(1)

        model = Model("model")
        rec = KaldiRecognizer(model, wf.getframerate())
        rec.SetWords(True)

        result = []
        text = ""

        while True:
            data = wf.readframes(4000)
            if len(data) == 0:
                break
            if rec.AcceptWaveform(data):
                print(f"rec.Result() = {rec.Result()}")
            else:
                print(rec.PartialResult())
                pass

You can ignore these warnings from now, they are from large pieces of music in your recording. We might work on such audios in the future, for now it is just a warning.

Thank you, the accuracy and speed of VOSK are very good.
