"Springest" is not a commonly used word, but when spelled out it looks like it should be pronounced with a hard "g" sound. In reality, the pronunciation is actually closer to "spring-ist" with a soft "g" sound. The IPA phonetic transcription for this word would be /ˈsprɪŋ.ɪst/. This is because the combination of the letters "ng" at the end of a word typically makes the "g" sound soft, as in "sing" or "ring."
