Automatic Video Subtitiles

Introduction

Automatic video subtitles can generate subtitles from a specific video by using the Automatic Speech Recognition (ASR) system.

This demo is an implementation to automatic video subtitles from a video file. It can be done by a single command or a few lines in python using PaddleSpeech.

Usage

1. Installation

pip install paddlespeech

2. Prepare Input

Get a video file with the speech of the specific language:

wget -c https://paddlespeech.bj.bcebos.com/demos/asr_demos/subtitle_demo1.mp4

Extract .wav with one channel and 16000 sample rate from the video:

ffmpeg -i subtitle_demo1.mp4 -ac 1 -ar 16000 -vn input.wav

3. Usage

  • Python API
    import paddle
    from paddlespeech.cli import ASRExecutor, TextExecutor
    
    asr_executor = ASRExecutor()
    text_executor = TextExecutor()
    
    text = asr_executor(
        audio_file='input.wav',
        device=paddle.get_device())
    result = text_executor(
        text=text,
        task='punc',
        model='ernie_linear_p3_wudao',
        device=paddle.get_device())
    print('Text Result: \n{}'.format(result))
    
    Output:
    Text Result:
