Are there anywhere written transcripts of what at least Daenerys says in the series?
The first time I saw Game of Thrones, there were no translations, no subtitles when they speak Valyrian, especially the long speeches of Daenerys.
So it was useless and a bit boring to listen to these long monologues, because I couldn´t figure out, what she was saying.
Maybe, the Duolingo course in addition to some another tools like memrize can help, but perhaps it may be a good exercise, trying to translate, what they say in the series.
Are there any written transcripts of what they say in Valyrian in the series availabe elsewhere?
Also, http://wiki.dothraki.org/Season_6_High_Valyrian_Dialogue (replace 6 with whatever season number, of corse)
The creator of the language David Peterson's blog has most, if not all, dialogue in Valyrian. Here is a search that will show (mainly) those posts: https://dedalvs.tumblr.com/search/valyrian%20dialogue%20episode
Heres a good video to start with https://www.youtube.com/watch?v=ICVT0ZnuKVY&t=290s
