微软TTS（textspeech）免费开源edgetts语音合成（Python3。10）

　　不能否认，微软Azure在TTS(text-to-speech文字转语音)这个人工智能细分领域的影响力是统治级的，一如ChatGPT在NLP领域的随心所欲，予取予求。君不见几乎所有的抖音营销号口播均采用微软的语音合成技术，其影响力由此可见一斑，仅有的白璧微瑕之处就是价格略高，虽然国内也可以使用科大讯飞语音合成进行平替，但我们只想要最好的那一个，本次我们使用免费的开源库edge-tts来实现文本转语音操作，薅微软edge的羊毛。 TTS文本转语音基础使用方式
　　首先安装edge-tts库： pip3 install edge-tts
　　安装成功后，直接在终端运行edge-tts命令： edge-tts
　　显示帮助菜单即代表安装成功： ➜  Downloads edge-tts usage: edge-tts [-h] [-t TEXT] [-f FILE] [-v VOICE] [-l] [--rate RATE] [--volume VOLUME] [-O OVERLAPPING]                 [--write-media WRITE_MEDIA] [--write-subtitles WRITE_SUBTITLES] [--proxy PROXY]
　　随后输入命令： edge-tts --list-voices
　　该命令可以将Edge浏览器中，内置的语言角色列表列出来： Name: af-ZA-AdriNeural Gender: Female  Name: af-ZA-WillemNeural Gender: Male  Name: am-ET-AmehaNeural Gender: Male  Name: am-ET-MekdesNeural Gender: Female  Name:

　　一望而知，几乎支持所有主流的通用语，Gender字段为合成语音的性别，Male代表男性，Female代表女性，zh开头的就是中文语音角色，这里以微软的小伊为例子： edge-tts --voice zh-CN-XiaoyiNeural --text ＂你好啊，我是智能语音助手＂ --write-media hello_in_cn.mp3
　　该命令含义是通过zh-CN-XiaoyiNeural角色合成语音：＂你好啊，我是智能语音助手＂的内容，随后将音频流写入hello_in_cn.mp3文件。
　　程序返回： Downloads edge-tts --voice zh-CN-XiaoyiNeural --text ＂你好啊，我是智能语音助手＂ --write-media hello_in_cn.mp3 WEBVTT  00:00:00.100 --> 00:00:00.525 你好  00:00:00.525 --> 00:00:00.912 啊  00:00:01.050 --> 00:00:01.238 我  00:00:01.238 --> 00:00:01.375 是  00:00:01.387 --> 00:00:01.700 智能  00:00:01.700 --> 00:00:02.050 语音  00:00:02.062 --> 00:00:02.550 助手
　　程序会自动将时间轴和语音文本匹配输出，如此一来，连字幕文件也有了，可谓是一举两得，一箭双雕。
　　与此同时，我们也可以调整合成语音的语速： edge-tts --rate=-50% --voice zh-CN-XiaoyiNeural --text ＂你好啊，我是智能语音助手＂ --write-media hello_in_cn.mp3
　　--rate参数可以通过加号或者减号同步加快或者减慢合成语音的语速。
　　亦或者，调整合成语音的音量： edge-tts --volume=-50%  --voice zh-CN-XiaoyiNeural --text ＂你好啊，我是智能语音助手＂ --write-media hello_in_cn.mp3
　　--volume参数可以调整语音的音量。
　　遗憾的是，和微软Azure官方的语音合成库相比，开源的语音合成库并不支持基于标记语言 (SSML)的语音调优，比如语调、情绪的调整，但这毕竟是免费的，要求也不能太高了。 Python脚本语音合成
　　除了通过命令进行语音合成，edge-tts也支持在Python脚本，编辑test.py文件： import asyncio  import edge_tts  TEXT = ＂你好哟，我是智能语音助手，小伊＂ VOICE = ＂zh-CN-XiaoyiNeural＂ OUTPUT_FILE = ＂/Users/liuyue/Downloads/test.mp3＂   async def _main() -> None:     communicate = edge_tts.Communicate(TEXT, VOICE)     await communicate.save(OUTPUT_FILE)   if __name__ == ＂__main__＂:     asyncio.run(_main())
　　这里我们直接通过异步模式调用communicate实例的save方法，就可以并发异步生成语音合成的音频文件，非常方便。
　　也可以通过语音管理库来自动寻找我们需要的语言： import asyncio import random  import edge_tts from edge_tts import VoicesManager  TEXT = ＂中文语音测试＂ OUTPUT_FILE =＂china.mp3＂   async def _main() -> None:     voices = await VoicesManager.create()     voice = voices.find(Gender=＂Female＂, Language=＂zh＂)      communicate = edge_tts.Communicate(TEXT, random.choice(voice)[＂Name＂])     await communicate.save(OUTPUT_FILE)   if __name__ == ＂__main__＂:     asyncio.run(_main())
　　这里通过内置的VoicesManager库来随机挑选中文语音角色完成语音合成操作。
　　除此之外，也可以通过脚本将语音流和字母同步进行生成： import asyncio  import edge_tts  TEXT = ＂这里是语音流测试＂ VOICE = ＂zh-CN-XiaoyiNeural＂ OUTPUT_FILE = ＂test.mp3＂ WEBVTT_FILE = ＂test.vtt＂   async def _main() -> None:     communicate = edge_tts.Communicate(TEXT, VOICE)     submaker = edge_tts.SubMaker()     with open(OUTPUT_FILE, ＂wb＂) as file:         async for chunk in communicate.stream():             if chunk[＂type＂] == ＂audio＂:                 file.write(chunk[＂data＂])             elif chunk[＂type＂] == ＂WordBoundary＂:                 submaker.create_sub((chunk[＂offset＂], chunk[＂duration＂]), chunk[＂text＂])      with open(WEBVTT_FILE, ＂w＂, encoding=＂utf-8＂) as file:         file.write(submaker.generate_subs())   if __name__ == ＂__main__＂:     asyncio.run(_main())
　　这里异步调用之后，音频会写入test.mp3，而字幕文件则会写入test.vtt。后续则可以通过ffmpeg将生成的字幕文件叠加到视频中即可，请参见：基于Python3(Autosub)以及Ffmpeg配合GoogleTranslation(谷歌翻译)为你的影片实现双语版字幕(逐字稿) 结语
　　开源语音合成edge-tts库可以提高语音合成效率，并且极大地降低了语音合成门槛，为自动化视频剪辑铺平了道路，未来结合基于Stable-Diffusion算法的AI绘图框架，人工智能AI一键式绘制、配音、上字幕的一条龙服务指日可待。
