Bug around Chinese Mandarin in Espeak has been discovered

[Giovani93]

Hi!
I have discovered bug in Mandarin Chinese of Espeak. Here is copy of My e-mail sent to one mailing list.
OK, bug is discovered, I think It is misstake of Espeak NG.
There are two voices classified, as Mandarin Chinese. One is incorrect and countains bugs. Two voices labelled, as Mandarin Chinese in direction with chinese voices.
Please, could You look to this folder and fix the bug?
Thank You.

Please, test It in this page, there are two Chinese mandarin Espeak and this is not very good for NVDA.

There is only one instance of each Chinese voice listed by espeak-ng, and via its API:

$ src/espeak-ng --voices | grep Chinese
 5  cmn             --/M      Chinese_(Mandarin) sit/cmn              (zh-cmn 5)(zh 5)
 5  yue             --/M      Chinese_(Cantonese) sit/yue              (zh-yue 5)(zh 8)

Therefore, this is a bug in the odo.lv page and NVDA.

NOTE: If they are not removing the previous voice files when copying over the new ones, they may have added duplicate voice entries from changes to the layout of that directory in previous versions of espeak-ng, including the move from the voices directory to the lang directory. In that case, the MBROLA voices and the voice variants are listed in the voices directory, while the languages are in the lang` directory.

I fixed list of languages on the test page.
I don't know about NVDA, but invoking espeak-ng in command line, cmn or zh-cmn, and yue or zh-yue work as synonyms for voice parameters:
