pocketsphinx实现离线语音识别出错

最近在研究离线语音识别，在运行以下代码时：

# -*- coding:utf-8 -*-

import speech_recognition as sr 

def wav2txt(wav_file,language):
    r = sr.Recognizer()
    audio= ""
    with sr.AudioFile(wav_file) as src:
        audio= r.record(src)
    print(r.recognize_sphinx(audio,language=language))

fp1=r'D:\pythondata\recording.wav'

wav2txt(fp1,"zh-CN")

出现错误提示：speech_recognition.RequestError: missing PocketSphinx phoneme dictionary file: "D:\software\python37\lib\site-packages\speech_recognition\pocketsphinx-data\zh-CN\pronounciation-dictionary.dict
请问有谁遇到过一样的问题？是如何解决的？

根据源码代码：
if not os.path.isfile(phoneme_dictionary_file):
raise RequestError("missing PocketSphinx phoneme dictionary file: "{}"".format(phoneme_dictionary_file))
在提示的目录下没有找到pronounciation-dictionary.dict文件，在zh-CN目录下应该有如下文件才可：

参考这里安装语音包的方法。
