Well the amount of syllables depends on the language. So far I was able to put all the Japanese syllables in one card, but for English there would be at least 300. Due to there being more than 6 vowels and a lot of constants. so for example, I have 8 vowels and 20 constants, they all need to be connected. I take "k" and add all the vowels, that's 8 syllables, multiply by 20, we get 160. But I also have to leave some space for the pause button, the vowels separately and the constants separately.
