Introduction : There exists a space between verbal and non-verbal communication systems, which is inconspicuous in the current taxonomy.  Through my research, I propose the use of the term Liminal Space of Communication (LSC) to indicate this position.

​

People in the Liminal Space of Communication system (PLSC) have a single or combination of speech variances with/without long term auditory impairments, along with childhood developmental and sensorineural hearing loss, excluding deafness, in which these conditions are not typically categorised as disability, but affect their quality of life on many fronts. Vowels are relatively easily accessible elements of verbal communication system for PLSC. 

Liminal space, along the milieu of interpersonal communication, is a place for 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 “aah”, "oh" , "oo" and  “ee” and the audience. Each of these digital entities respond to distinct vowel sounds and react to certain intonations and volume of the vowels sounds . This work uses AI (custom trained CNN machine learning model), and the vintage optical technology 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.
