python 使用语音识别后无法删除音频文件

Question

这是我的语音转文本测试代码，语音转文本有效，唯一的问题是在

之后删除音频文件

   import os
from os import walk
import speech_recognition as sr


def remove_spaces(string) : # removes all spaces in a string
    return string.replace(" ", "")


def search_name() : # search for any file in path
    _, _, filenames = next(walk('C:\audios\')) 
    return filenames[0]


def remove_file(name) : # should look for the file and removes it 
    print(('C:\audios\' + name))
    if os.path.isfile(('C:\\audios\' + name)) :
        os.remove(('C:\audios\' + name))
        print("success, file .waw removed!")
    else :
        print("File doesn't exists!")


def main() :
    r = sr.Recognizer()  
    audio_name = search_name() #get the name of file
    print("Filename of Audio:", audio_name)
    with sr.AudioFile(f'C:\audios\{audio_name}') as source :
        audio_text = r.listen(source)
        text = r.recognize_google(audio_text, language='de-DE')
        print('Converting audio transcripts into text ...')
        code = remove_spaces(text)
        print(code)
        remove_file(audio_name)
        return code


if __name__ == '__main__' :
    main()

错误，在使用语音转文本后我想删除 'audio.waw' 但它说该文件仍在使用中

    C:\Users\J-Roc\AppData\Local\Programs\Python\Python39\python.exe C:/speech_to_text.py
Filename of Audio: xyz.wav
Traceback (most recent call last):
  File "C:\speech_to_text.py", line 43, in <module>
    main()
  File "C:\speech_to_text.py", line 38, in main
    remove_file(audio_name)
  File "C:\speech_to_text.py", line 20, in remove_file
    os.remove(('C:\audios\' + name))
PermissionError: [WinError 32] The process cannot access the file because it is used by another process: 'C:\audios\xyz.wav'

Answer 1

您正在删除文件上下文中的文件。您应该在上下文完成后删除。在你的主要功能中：

with sr.AudioFile(f'C:\audios\{audio_name}') as source :
        audio_text = r.listen(source)
        text = r.recognize_google(audio_text, language='de-DE')
        print('Converting audio transcripts into text ...')
        code = remove_spaces(text)
        print(code)
        remove_file(audio_name) #Still inside the file context. Can't remove file. 
remove_file(audio_name)
return code

还强烈建议使用 try-except。

现在对我有用了，谢谢 :)

  def main() :
    r = sr.Recognizer()
    audio_name = search_name()
    print("Filename of Audio:", audio_name)
    with sr.AudioFile(f'C:\ms_acc_creator_\audios\{audio_name}') as source :
        audio_text = r.listen(source)
        text = r.recognize_google(audio_text, language='de-DE')
        print('Converting audio transcripts into text ...')
        code = remove_spaces(text)
        print(code)

    remove_file(audio_name)
    return code


if __name__ == '__main__' :
    main()
