如何在python中的波形文件中转换电报语音 [英] How to convert Telegram voice in a wave file in python

问题描述

我正在尝试使用声音文件库将 Telegram 语音文件保存在波形音频文件中:

I'm trying to save a Telegram voice file in a wave audio file using soundfile library:

def ReceiveVoice(bot, update, user_data):

   voice = bot.getFile(update.message.voice.file_id)
   voice.download('file.ogg')
   data, samplerate = sf.read('file.ogg')
   sf.write('file.wav', data, samplerate)

但我收到以下错误:

File "C:\Python27\lib\site-packages\soundfile.py", line 257, in read
subtype, endian, format, closefd) as f:
File "C:\Python27\lib\site-packages\soundfile.py", line 624, in __init__
self._file = self._open(file, mode_int, closefd)
File "C:\Python27\lib\site-packages\soundfile.py", line 1179, in _open
"Error opening {0!r}: ".format(self.name))
File "C:\Python27\lib\site-packages\soundfile.py", line 1352, in _error_check
raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace'))
RuntimeError: Error opening 'file.ogg': File contains data in an unimplemented format.

推荐答案

你可以尝试使用 ffmpeg通过使用 python 的模块子进程执行以下命令行，将 ogg 转换为 wav.

You could try to use ffmpeg to convert from ogg to wav by executing the following command line using python's module subprocess.

import subprocess
src_filename = 'captured.ogg'
dest_filename = 'output.wav'

process = subprocess.run(['ffmpeg', '-i', src_filename, dest_filename])
if process.returncode != 0:
    raise Exception("Something went wrong")
