The word "Helkai" may seem peculiar at first glance, but its spelling can be explained using the International Phonetic Alphabet (IPA). The "H" represents a voiceless glottal fricative sound, similar to the "h" in "hat." The "e" is pronounced with an "eh" sound, as in "bed," followed by a "l" sound. The "k" represents a hard "k" sound, similar to "cat." Finally, the "ai" combination can be pronounced as the diphthong "eye," giving the word a unique and memorable sound.
