Correct.
When I first saw Peanuts comics on TV, with Finnish subtitles, I couldn't get the spelling contests. I thought: "You hear the sound, so it is obvious which letter will correspond". Then we started learning English, Swedish, German....
Finnish spelling vs. pronunciation is very consistent. When you see a letter, there's just one sound that can correspond to it, in pronunciation - with few minor exceptions. Like, in Lapua, both "a" letters produce the same sound: "ah". If you have to divide Lapua into syllables, it actually goes la-pu-a.
