使用 OpenAI Whisper 和 GPT 的 YouTube 视频摘要器

此 Python 脚本允许您使用 OpenAI 的 Whisper 进行音频转录，并使用 GPT 生成简洁的视频摘要来总结 YouTube 视频。该管道涉及下载 YouTube 视频的音频，使用 Whisper 进行转录，然后使用 GPT 生成摘要。

先决条件

在开始之前，请确保您拥有必要的 Python 库和 OpenAI API 密钥：

Python (>=3.6)
whisper库（用于音频转录）
openai库（适用于 GPT）
pytube库（用于下载 YouTube 视频）

您还应该将 OpenAI API 密钥设置为环境变量。

脚本概述

1. 下载 YouTube 视频

该脚本首先从 YouTube 视频下载音频。它使用pytube库来获取视频，选择纯音频流，并将其保存为音频文件。

 youtube_video = YouTube ( YOUTUBE_VIDEO_URL )
streams = youtube_video . streams . filter ( only_audio = True )
# taking first object of lowest quality
stream = streams . first ()
stream . download ( filename = OUTPUT_AUDIO )

2. 使用 Whisper 进行音频转录

接下来，使用 Whisper 模型转录音频。 Whisper库用于加载Whisper模型、转录音频并获取转录本。

 model = whisper . load_model ( WHISPER_MODEL )
transcript = model . transcribe ( OUTPUT_AUDIO . as_posix ())
transcript = transcript [ 'text' ]
print ( f'Transcript generated: n { transcript } ' )

3.用GPT总结

然后，该脚本使用 GPT 生成转录文本的简明摘要。它提供系统提示和用户提示来指示 GPT 生成有意义的摘要。

 model = whisper . load_model ( WHISPER_MODEL )
transcript = model . transcribe ( OUTPUT_AUDIO . as_posix ())
transcript = transcript [ 'text' ]
print ( f'Transcript generated: n { transcript } ' )    system_prompt = "I would like for you to assume the role of a Life Coach"
    user_prompt = f"""Generate a concise summary of the text below.
    Text: { transcript }
    
    Add a title to the summary.

    Make sure your summary has useful and true information about the main points of the topic.
    Begin with a short introduction explaining the topic. If you can, use bullet points to list important details,
    and finish your summary with a concluding sentence"""
    #
    print ( 'summarizing ... ' )
    response = openai . ChatCompletion . create (
        model = 'gpt-3.5-turbo-16k' ,
        messages = [
            { 'role' : 'system' , 'content' : system_prompt },
            { 'role' : 'user' , 'content' : user_prompt }
        ],
        max_tokens = 4096 ,
        temperature = 1
    )
    #
    summary = response [ 'choices' ][ 0 ][ 'message' ][ 'content' ]

用法

将 OpenAI API 密钥设置为环境变量。
使用 pip 安装所需的 Python 库（whisper、openai、pytube）。
修改脚本，将 OPENAI_API_KEY 和 YOUTUBE_VIDEO_URL 替换为您的 OpenAI API 密钥和您要摘要的 YouTube 视频的 URL。
使用 python summarise_youtube_videos.py 运行脚本。
