Babble Wall (2019). Babble is a sentimental voice assistant constantly listening to its surroundings and desperately wanting to be stimulated by humans around it. It seeks attention by expressing its emotional state through animated clips (gifs) and by talking about it. It wants to be praised, complimented and loved, which the audience can do by talking into the microphone. Else, it starts getting depressed and calls out for attention. Positive utterances elevate Babble, whereas negative utterances make it hate and curse you. Babble is developed using NLP (natural language processing) machine learning services that enables it to interpret what it hears from the audience and react to it accordingly. Talk to Babble yourself.
