Pronunciation: [ˈɒsts] (IPA) 
The spelling of the word "OSTS" follows the standard English pronunciation rules. The first letter "O" makes the "oh" sound and the "S" at the end makes the "ss" sound. However, the tricky part is the middle letter, which is pronounced as a "t" sound. This is because it is a silent letter "H" that follows the "t." Therefore, the IPA transcription for "OSTS" is /oʊsts/ with a silent "h" making the "t" sound in the middle.
