This deck provides cards with the letters of Spanish, diphthongs and some combination of letters, with a condition when letters or clusters of letters should be pronounced in some particular way.
A lot of sounds and words in examples have a video example of pronunciation.
The resources I used are the book 'Modern Spanish Grammar: A Practical Guide. Second Edition' and this site

If you have some concerns about my deck, you can write them down in the comment section, I will be happy to read them and update my deck so other people may make more profit out of it.
