python - 语音识别python代码不起作用

Question

我在安装了 pyAudio 的 Python 2.7 中运行以下代码。

import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:                # use the default microphone as the audio source
    audio = r.listen(source)                   # listen for the first phrase and extract it into audio data

try:
    print("You said " + r.recognize(audio))    # recognize speech using Google Speech Recognition
except LookupError:                           # speech is unintelligible
    print("Could not understand audio")

输出给出了一个闪烁的指针。就是这样。

可能的原因可能是 recognizer_instance.energy_threshold 属性设置的值可能太高而无法开始。您应该降低此阈值，或调用 recognizer_instance.adjust_for_ambient_noise(source, duration = 1)。您可以在 Speech Recognition 了解更多信息
