使用Python，如何用Whisper来转写音频至SRT字幕

import whisper
import json
import os
import datetime

import whisper.utils

def transcription(audioPath: str, model: whisper.Whisper) -> list:
    '''
    Transcribe the audio file at the given path. The result is in str format.
    '''
    result = model.transcribe(audioPath, verbose=False, language="en")
    return result

def batchTranscription(audioFolder: str, outputFolder: str):
    '''
    Transcribe the audio file at the given path. The result is in str format.
    '''
    model = whisper.load_model("large-v3")
    writer = whisper.utils.WriteSRT(outputFolder)

    if not os.path.exists(outputFolder):
        os.makedirs(outputFolder)
    
    for root, dirs, files in os.walk(audioFolder):
        for file in files:
            if file.endswith(".mp3"):
                scriptPath = os.path.join(outputFolder, file.replace(".mp3", ".srt"))
                audioPath = os.path.join(root, file)
                result = transcription(audioPath, model)

                with open(scriptPath, 'w') as f:
                    writer.write_result(result, f)

def main():
    audioFolder = 'Audio'
    outputFolder = 'output'
    batchTranscription(audioFolder, outputFolder)

main()
