Question

我正在尝试使用SpeechRecognition库（https://pypi.python.org/pypi/SpeechRecognition/）。在下面运行示例代码（full example）时：

#!/usr/bin/env python3

import speech_recognition as sr

# obtain path to "english.wav" in the same folder as this script
from os import path
AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "english.wav")
#AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "french.aiff")
#AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "chinese.flac")

# use the audio file as the audio source
r = sr.Recognizer()
with sr.AudioFile(AUDIO_FILE) as source:
    audio = r.record(source) # read the entire audio file

我收到此错误：

如何解决这个问题？

Answer 1

我有一段时间遇到同样的问题，我的错误是使用＆＃34下载wav文件;另存为＆＃34;。当我双击播放wav文件时，我无法使用任何播放器播放wav文件。克隆或下载整个zip文件后，我可以播放wav文件，错误消失。

Answer 2

您的wav文件可能已损坏。要进行检查，请尝试尽可能使用任何媒体播放器播放文件。将音频文件正确下载到您的环境中，然后它应该可以工作。

当我通过错误的方式下载文件而出错时，我遇到了这个问题，我在Google colab中使用以下命令下载了音频文件：

[!wget 'https://github.com/mozilla/DeepSpeech/blob/master/data/smoke_test/LDC93S1_pcms16le_1_16000.wav']

由于音频文件已损坏，这引发了错误（下载时无法在媒体播放器上播放）。通过下载以下方法，我得以解决此问题：

[!wget 'https://raw.githubusercontent.com/mozilla/DeepSpeech/master/data/smoke_test/LDC93S1_pcms16le_1_16000.wav']

Answer 3

无论如何，当我存储在存储库中的 git LFS WAV 文件没有正确克隆时，我遇到了这个问题。他们的指针存在，但文件不存在。一个

git lfs pull

解决了问题。

话虽如此，这可能只是在您指向的文件实际上不是“完整”的音频文件时发生。希望有帮助！
