How often do we think of vowel sounds given that we use them in every single utterance we make? What if vowels are the only sounds we could produce and in that case how can we communicate using only vowels?

Liminal space' along the milieu of interpersonal communication, is a place of exchanges of dispositions between verbal and non-verbal communication systems.  Linking these two agencies are Vowels from verbal communication system and Gestures from non-verbal communication system. In this work, an introductory relationship is formed between the artificial digital entities called Liminilians “aaaah” and  “eee…ee..eeee” and the audience. Each of these digital entities respond to separate vowel sounds and sometimes react to intonations and volume of the vowels sounds . This work uses AI (custom trained CNN  machine learning model), and ancient technique of holographic projection -Pepper’s ghost effect (named after the inventor John Henry Pepper ), to create a temporary liminal space and to establish an intimate and relatively 'natural' relationship through and with vowels.
