The word "ASLE" is spelled using four letters, with a relatively simple phonetic transcription: /æsl/. The first sound, /æ/, is similar to the "a" sound in "cat." The second sound, /s/, is a voiceless fricative, produced by forcing air through a tight opening in the mouth. The final sound, /l/, is a voiced lateral approximant, produced by touching the tongue to the alveolar ridge while allowing air to flow out around the sides. Together, these sounds make up the word "ASLE."
