It is possible to show on the .mdx the speaker’s votes, country, and sex.
The German Forvo .mdx (Full Version) shows that info:

The data about votes, speaker, sex and country is available in the metadata of Forvo Audios:
Check the folder called “Z (Tools related to Electronic Dictionaries - Scripts & Software)” > Forvo Scraping Tools.
However, it is a difficult job to use the metadata. I cannot do it by myself. IMHO, it is acceptable just to compile a “simple” .mdx that shows all the pronunciations.
The German Forvo was compiled by Xu Yinuo. He wrote a custom python script to process the metadata but the code is unreadable even for him after few months… It is messy to deal with metadata. Anyway, if you want you could use it…
