The spelling of the word "WEMP" is quite unique and can be explained using IPA phonetic transcription. The first letter "W" represents the voiced labio-velar approximant /w/, which is produced by rounding the lips and raising the back of the tongue to the velum. The following three letters "EMP" represent a voiceless bilabial nasal /m/ followed by an unvoiced bilabial plosive /p/. Thus, the word "WEMP" is pronounced as /wɛmp/ with emphasis on the final consonant sound.
