A Korean alphabet block assembly is provided to increase a spatial perception ability of infants as well as a language learning ability, by integrating block play with audio-visual education. A Korean alphabet block assembly includes plural vowel blocks(10) and plural consonant blocks(30,31'), in which each of the vowel block and consonant block or a combined vowel and consonant block makes corresponding voice. The consonant block outputs voice information of a corresponding consonant from a memory for the consonant block, and the vowel block outputs voice information of a corresponding vowel from a memory for the vowel block. The combined vowel and consonant block outputs voice information if the combined block corresponds to a preset word.
