# 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
|
|
see [installation](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/install.md).
|
|
|
|
You can choose one way from easy, meduim and hard to install paddlespeech.
|
|
|
|
### 2. Prepare Input
|
|
Get a video file with the speech of the specific language:
|
|
```bash
|
|
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:
|
|
```bash
|
|
ffmpeg -i subtitle_demo1.mp4 -ac 1 -ar 16000 -vn input.wav
|
|
```
|
|
|
|
### 3. Usage
|
|
|
|
- Python API
|
|
```python
|
|
import paddle
|
|
from paddlespeech.cli.asr import ASRExecutor
|
|
from paddlespeech.cli.text import 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:
|
|
```bash
|
|
Text Result:
|
|
当我说我可以把三十年的经验变成一个准确的算法，他们说不可能。当我说我们十个人就能实现对十九个城市变电站七乘二十四小时的实时监管，他们说不可能。
