Coqui TTS 安装与测试
前言
本篇记录一下 Coqui TTS 的安装。Coqui-TTS 的主要作者是德国人,这个库似乎之前和 Mozilla 的 TTS (https://github.com/mozilla/TTS)有千丝万缕的关系,但是现在后者的 TTS 已经停止更新,而 Coqui TTS 更新一直很稳定,是目前少数几个更新比较稳定的开源语音库。(其他有 ESPNET,SpeechBrain 等)
GitHub 官网:
正文
首先直接跳到 Readme 的安装部分。
pip install TTS
或者
git clone https://github.com/coqui-ai/TTS pip install -e .[all,dev,notebooks] # Select the relevant extras
直接用 pip 感觉就不太行,当然要 git clone 一下,极客一点。结果第二行就没看懂,pip install -e 是什么,后面方括号是什么……(-e 表示拉了一个链接,目录的更新实时生效;方括号及方括号内的东西其实不加也行)
于是还是 pip install TTS 了
这里普通用户应该直接开始漫长等待就好了,注意 TTS 是依赖 torch 的,由于 torch 庞大的体积,所以可能是要等很久。但是我这里由于环境问题,只能用特定版本的 torch,否则用不了 GPU。。所以就要先安装 torch 在安装 TTS了,避免自动安装的 torch 无法使用。这里 TTS 的依赖是 torch 版本大于 1.7 即可。
下面是克隆环境的 conda 的命令:
conda create --name coquiTTS --clone espnet
--clone 命令能够复制之前的库,速度应该是稍微快一点,但是实测会重新下载 torch,不知道是什么原因,暴躁的我直接 cp 命令手动拷贝了hh(目前似乎没有什么坏的影响,本来还以为会有一些元文件被覆盖会出错 )
好,影响就是我 pip 安装的包都安装回原来的路径了,手动捂脸哭,本来想着不要影响原来的环境,正确的解法是 加上 --offline
conda create --name coquiTTS --clone original_env --offline
不知道为什么,torch 本来我本机环境有,还是会要自己下载,offline 模式会报错,说尝试 offline 模式建立远程连接。所以只能
conda create --name coquiTTS --clone original_env
复制环境后,pip 安装 TTS,会有很多乱七八糟的依赖,所以记得设置源。不然会很慢:
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
pip install TTS
安装完会有很长很长的输出。(结果是我给安装到原来的环境里了)
测试
先是官方的测试。
tts --list_models
这里的输出是(TTS版本 0.8.0):

tts --text "text for TTS" --out_path ./test_speech.wav
终于到了激动人心的时刻,要合成语音了。执行命令后,开始自动下载预训练模型,用了 3 分钟,经典连接中断报错。网络环境,哎。

During handling of the above exception, another exception occurred:
注意!Coqui 下载模型失败后,并没有检查有没有下载成功。这个再次合成,会报错。需要自己手动删掉下载的目录,再重新下载,否则会一直报错。参考链接:https://github.com/coqui-ai/TTS/issues/927
cd ~/.local/share/tts/
rm -r tts_models--en--ljspeech--tacotron2-DDC/
然后非常玄学的事情发生了,我再次尝试下载时,没有做任何修改,就下载成功了。所以同学们可以多尝试几次。
tts --text "text for TTS" --out_path ./test_speech.wav

后面这个库应该是提供 tts server 开一个 HTTP 端口做在线 demo 的,但是我这里因为环境问题可能要之后更了。
后记
20230217 更新,发现 TTS 库会限定 librosa==0.8.0,导致我的 librosa 版本不对,然后画频谱图和 Matplotlib 的 API 会不兼容,进而报错。于是默认环境的 TTS 就卸载了。
