我想使应用程序，使字幕为视频我提取音频文件如下

import sys
from moviepy.video.tools.subtitles import SubtitlesClip
from moviepy.editor import *
video = VideoFileClip(sys.argv[1])
audio = video.audio
audio.write_audiofile()

我把它转换成文本，但我想记录的时间，使srt文件..我可以记录的时间，当有语音在音频文件或任何方式，使srt文件从音频文件，下面的代码是转换音频到文本

import speech_recognition as sr

AUDIO_FILE=("audi.wav")
r=sr.Recognizer()

with sr.AudioFile(AUDIO_FILE) as source:
    audio=r.record(source)
    # sr.recognize_api()
    googletext = r.recognize_google(audio)
    with open("audio5.txt","w") as f:
            f.write(googletext)
    with open("audio.srt","w") as f:
            f.write(googletext)
