For bots to recognize and be able to interpret to natural language is no easy task. This is why there are currently hurdles to overcome in this field related to speech recognition, natural language recognition and natural language generation. This, however often requires natural language understanding. Gathering user voice data and data related to how users ask questions in various ways is one way to improve these services and natural language processing on voice bots as a whole. Either way, voice recognition and smart speakers are here to stay and may speed up the overall development of natural language processing albeit at the expense of privacy.
