Logs

TTS/TTS/tts/layers/xtts/tokenizer.py", line 180, in expand_abbreviations_multilingual
    for regex, replacement in _abbreviations[lang]:
KeyError: 'zh-cn'

Environment

    for regex, replacement in _abbreviations[lang]:
KeyError: 'zh-cn'

If zh-cn and zh represent Chinese, it is recommended to use one.

如果想运行可以手动先更改TTS文件下tokenizer.py中118行和283行 zh改为zh-cn

[lucasjinreal]

I think the tokenizer these map's keys should be consistent with language codes.

before offical fix

pip uninstall TTS
pip install TTS==0.20.2

work!

可以啊兄弟，对了，兄弟知道怎么保存说话人的潜在特征和嵌入，使用这些特征生成多段对话吗？现在每次都要先生成特征，再推理，效率很低

[lucasjinreal]

@jbang2004 可以，但是官方似乎压根没有考虑这个问题

研究了一个上午，官方文档里有个直接从模型提取特征，然后用torchaudio生成wav的方法，这个可以一直沿用相同的特征进行转换，不过这种方法生成的效果比使用api差一些，不知道为什么

@jbang2004 方便分享一下代码吗

I fixed it on https://github.com/coqui-ai/TTS/pull/3216. "zh-cn" is what we have in the config and docs so I rename "zh" to "zh-cn".

[genglinxiao]

I think there are 2 places that the key code used for Chinese language are inconsistent: The model uses "zh-cn" for the Chinese (simplifed) language. However, the key defined in the _abbreviations and the _symbols_multilingual for Chinese language is "zh". These 2 structures are used in expand_abbreviations_multilingual() and expand_symbols_multilingual() respectively, resulting in key errors.

In my case, I changed the key from "zh-cn" to "zh" inside these 2 functions by adding the following lines to the functions.

    if lang=="zh-cn":
        lang="zh"

But I think there ought to be a cleaner solution.
