前言
Whisper 是一种通用语音识别模型。它是在大量不同音频数据集上进行训练的，也是一个多任务模型，可以执行多语言语音识别、语音翻译和语言识别。
这里呢，我将给出我的一些代码，来帮助你尽快实现【语音转文字】的服务部署。
以下是该AI模块的具体使用方式：

心得
这是一个不错的语言模型，它支持自动识别语音语种，类似中文、英文、日语等它都能胜任，并且可以实现其他语种转英语翻译的功能，支持附加时间戳的字幕导出功能......
总体来说，它甚至可以与市面上领头的语言识别功能相媲美，并且主要它是开源的。
这是它的一些模型大小、需要的GPU显存、相对执行速度的对应表
这是它在命令行模式下的使用方式，这对想要尝尝鲜的小伙伴们来说，已经够了
tips：
1、首次安装完毕whisper后，执行指令时会给你安装你所选的模型，small、medium等，我的显卡已经不支持我使用medium了
2、关于GPU版本的pytorch，可以参考如下教程（使用CPU版本会比较慢）

python调用
作为一名python从业者，我十分幸运能够读懂一些模块的相关使用，这里我通过修改了一些模块源码调用，实现了在python代码中一键导出语音字幕的功能（这些功能在命令行中已拥有，但是我希望在使用python脚本model方法后再实现该功能，可能这些你并不需要，但随意吧）。
这个模块的cli()方法或许能更好实现这一功能（因为命令行模式，其实就是运行了这个方法，但我根据经验和实际代码来看，这会重复加载model，导致不必要的资源损耗）。
1、init.py中加入get_writer，让你能通过whisper模块去使用这个方法
python
from .transcribe import get_writer2、相关功能代码
python
import os.path
import whisper
import time

# 以下命令将使用medium模型转录音频文件中的语音：
#
# whisper audio.flac audio.mp3 audio.wav --model medium
# 默认设置（选择模型small）非常适合转录英语。要转录包含非英语语音的音频文件，您可以使用以下选项指定语言--language：
#
# whisper japanese.wav --language Japanese
# 添加--task translate会将演讲翻译成英语：
#
# whisper japanese.wav --language Japanese --task translate
# 其他语言转录为英语
# whisper "E:\voice\恋愛サーキュレーション_(Vocals)_(Vocals).wav" --language ja --task translate
# 这个任务是将audio_files内的声音文件进行字幕导出，以时间戳为单位存储到captions/目录里
