使用必剪API的语音字幕识别
Project description
Bcut-ASR
使用必剪 API 进行云端语音字幕识别,支持 CLI 和 module 调用
✨Feature
- 可直接上传
flac,aac,m4a,mp3,wav音频格式 - 自动调用 ffmpeg, 实现视频伴音和其他音频格式转码
- 支持
srt,json,lrc,txt格式字幕输出 - 字幕支持断句和首位时间标记
- 可使用 stdout 输出字幕文本
🚀Install
首先确保 ffmpeg 已安装,且 PATH 中可以访问,若未安装可以使用如下命令(已安装请无视):
Linux:
sudo apt install ffmpeg
Windows:
winget install ffmpeg
本项目暂时未发布 pypi,应使用本地安装,Python 版本应 >= 3.10,需要安装 poetry
git clone https://github.com/SocialSisterYi/bcut-asr
cd bcut-asr
poetry lock
poetry build -f wheel
pip install dist/bcut_asr-0.0.3-py3-none-any.whl # Example
📃Usage
CLI Interface
bcut_asr video.mp4
或
bcut_asr video.mp4 subtitle.srt
或
bcut_asr video.mp4 -f srt - > subtitle.srt
长音频指定任务状态轮询间隔(秒),避免接口频繁调用
bcut_asr video.mp4 -f srt -i 30 - > subtitle.srt
bcut_asr -h
usage: bcut-asr [-h] [-f [{srt,json,lrc,txt}]] [-i [1.0]] input [output]
必剪语音识别
positional arguments:
input 输入媒体文件
output 输出字幕文件, 可stdout
options:
-h, --help show this help message and exit
-f [{srt,json,lrc,txt}], --format [{srt,json,lrc,txt}]
输出字幕格式
-i [1.0], --interval [1.0]
任务状态轮询间隔(秒)
支持输入音频格式: flac, aac, m4a, mp3, wav 支持自动调用ffmpeg提取视频伴音
Module
from bcut_asr import BcutASR
from bcut_asr.orm import ResultStateEnum
asr = BcutASR('voice.mp3')
asr.upload() # 上传文件
asr.create_task() # 创建任务
# 轮询检查结果
while True:
result = asr.result()
# 判断识别成功
if result.state == ResultStateEnum.COMPLETE:
break
# 解析字幕内容
subtitle = result.parse()
# 判断是否存在字幕
if subtitle.has_data():
# 输出srt格式
print(subtitle.to_srt())
输入视频
from bcut_asr import run_everywhere
from argparse import Namespace
f = open("file.mp4", "rb")
argg = Namespace(format="srt", interval=30.0, input=f, output=None)
run_everywhere(argg)
