The spelling of the word "STSTABLE" may seem confusing at first, but it can be broken down into its phonetic components. The first "ST" sounds like /st/, as in "stop" or "stay." The following "S" is more like a hiss, with the phonetic symbol /s/, as in "snake" or "sister." The final "TABLE" is easier to recognize, with the sound /teɪbl/, as in "table" or "stable." Therefore, the correct pronunciation of "STSTABLE" would be /stseɪbl/.
