用于桌面应用程序的 Python 语音识别

Question

我一直在尝试使用库在桌面上收听音频speech_recognition，但不知道如何实现它......例如：假设我们在后台播放 YouTube 视频，如何将语音（在桌面背景中）转换为文本？

Answer 1

尝试这个

import speech_recognition as sr

r = sr.Recognizer()

m = sr.Microphone()

try:

    print("A moment of silence, please...")

    with m as source: r.adjust_for_ambient_noise(source)

    print("Set minimum energy threshold to {}".format(r.energy_threshold))

    while True:

        print("Say something!")

        with m as source: audio = r.listen(source)

        print("Got it! Now to recognize it...")

        try:

            value = r.recognize_google(audio)

            if str is bytes:

                print(u"You said {}".format(value).encode("utf-8"))

            else:

                print("You said {}".format(value))

        except sr.UnknownValueError:

            print("Oops! Didn't catch that")

        except sr.RequestError as e:

            print("Uh oh! Couldn't request results from Google Speech Recognition service; {0}".format(e))

except KeyboardInterrupt:

    pass
