Python 3 和袖珍狮身人面像

Question

我正在尝试通过对音频控制的音乐播放器进行编程来为我的祖父创建一个简单的音乐播放器，他的按钮有问题。我正在使用带有 Python 3 和 Pocket Sphinx 的 Raspberry Pi 3。因为 Pocket Sphinx 不需要 Internet，所以我会使用它，因为我的祖父无法访问 Internet。

我的问题是如何获取“说”的值，例如：“播放按钮”并让它播放波形文件“按钮”？

这是我必须构建的基本程序：

import speech_recognition as sr
import pygame
from pygame import mixer
mixer.init()

r = sr.Recognizer()
m = sr.Microphone()

Button = pygame.mixer.Sound('/home/pi/Downloads/button8.wav')

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:
            # recognize speech using Sphinx
            value = r.recognize_sphinx(audio)
            print("You said {}".format(value)) #uses unicode for strings and this is where I am stuck
            pygame.mixer.Sound.play(Button)
            pygame.mixer.music.stop()
        except sr.UnknownValueError:
            print("Oops! Didn't catch that")
        except sr.RequestError as e:
            print("Uh oh! Couldn't request results; {0}".format(e))
except KeyboardInterrupt:
    pass

非常感谢您提供的任何帮助。请善待，因为我是初学者。

尝试将其与“播放按钮”进行比较：

# recognize speech using Sphinx
value = r.recognize_sphinx(audio)
print("You said {}".format(value))

if value.lower() == 'play button':
    pygame.mixer.Sound.play(Button)
    pygame.mixer.music.stop()
