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：

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 = municate(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 = municate(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 = municate(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。
