The spelling of the word "kolts" may seem unusual at first glance. However, the IPA phonetic transcription reveals the reasoning behind this spelling. The "k" at the beginning is pronounced as a hard "k" sound, followed by the "o" sound which is pronounced as in "no". The "l" and "t" are pronounced as they are written, and the "s" at the end is pronounced as a soft "z" sound. Thus, the phonetic transcription of "kolts" is /kɒlts/.
