I am interested in self-study resources to improve my mandarin pronunciation (improve pinyin syllabes and also tone pronounciation).
There are many resources to self study writing/reading skills here but I haven't found anything too advanced for phonetics (i.e. most people just record themselves).
Is there any app/software that shows your tones/syllabe pronunciation and gives you advice on what to correct? Recording oneself can be good but I am looking for something better.
