Include IPA in lessons?
I think it would be easier to use the International Phonetic Alphabet for choosing the sounds made letters and syllables. There's a lot of confusion in the current system.
The goal of this course is to teach Hindi through Devanagari. So, it makes sense to start with the Latin letters according to the ISO15919 transliteration scheme which has a 1-1 correspondence with the Devanagari letters. If you are familiar with IPA, refer to this page (https://en.wikipedia.org/wiki/Help:IPA/Hindi_and_Urdu) as a rough guide to the pronunciation of the letters.
@Vinay92, Thanks for sharing, I don't remember ISO15919 although I have seen the IAST -https://en.wikipedia.org/wiki/International_Alphabet_of_Sanskrit_Transliteration
An IPA learning course on Duolingo would be awesome and even better if we could see IPA in the lessons.

Although, from my understanding the way Sanskrit was originally devised it's an ingenious natural ancient IPA of sorts, is it not?
Yes. ISO15919 is mostly an extension of IAST to encompass all Indic scripts and languages.
As a phonetic language, Sanskrit could be said to be similar to IPA in many ways. However, it is to be noted that Sanskrit is not immune to vowel and consonant shifts which can be seen in the differences between Vedic and classical Sanskrit.
You make a great point about vowel and consonant shifts, etc.
