python - 在按键上停止语音识别

问题描述

我可以停止在键盘按下时收听音频吗？我尝试像这样更改记录函数（在init.py中）：

    def record(self, source, duration=None, offset=None):
        """
        Records up to ``duration`` seconds of audio from ``source`` (an ``AudioSource`` instance) starting at ``offset`` (or at the beginning if not specified) into an ``AudioData`` instance, which it returns.

        If ``duration`` is not specified, then it will record until there is no more audio input.
        """
        assert isinstance(source, AudioSource), "Source must be an audio source"
        assert source.stream is not None, "Audio source must be entered before recording, see documentation for ``AudioSource``; are you using ``source`` outside of a ``with`` statement?"

        frames = io.BytesIO()
        seconds_per_buffer = (source.CHUNK + 0.0) / source.SAMPLE_RATE
        elapsed_time = 0
        offset_time = 0
        offset_reached = False
        while True:  # loop for the total number of chunks needed
            if offset and not offset_reached:
                offset_time += seconds_per_buffer
                if offset_time > offset:
                    offset_reached = True

            buffer = source.stream.read(source.CHUNK)
            if len(buffer) == 0: break

            if offset_reached or not offset:
                elapsed_time += seconds_per_buffer
                if keyboard.read_key() == "p":
                    print("\nYou pressed p")
                    break

                frames.write(buffer)

        frame_data = frames.getvalue()
        frames.close()
        return AudioData(frame_data, source.SAMPLE_RATE, source.SAMPLE_WIDTH)

并像这样从我的主脚本中调用它：

def Main():
r = sr.Recognizer()
try:
    with sr.Microphone() as source:
        print("Listening....")
        audio = r.record(source)
        print("Recognizing....")
        r.adjust_for_ambient_noise(source)
    text = r.recognize_google(audio)
    print(text.lower())
    if "lock computer" in text.lower():
        ctypes.windll.user32.LockWorkStation()
    elif "joke" in text.lower():
        joke = pyjokes.get_joke()
        speak(joke)
except Exception as e:
    print(e)
    Main()

当我按 p 但无法识别时，这会收听音频并停止收听

解决方案

我想通了，我保存了输入文件，发现里面没有音频，所以谷歌无法重新识别它。错误出现在此块中：

                if keyboard.read_key() == "p":
                    print("\nYou pressed p")
                    break

我将其更改为：

                if keyboard.read_key() == "p":
                    print("\nYou pressed p")
                    pressed = True
                    break

并复制监听功能并复制它，将其名称更改为listen1 现在当我按P 时它停止监听并且识别也在工作。奇迹般有效 。
