Based on the intent, a response is returned, again within a larger JSON response, either as a string or as SSML (more on that later). The JSON is then processed (usually in the cloud) to work out the context and intent of the request.By the magic of AI (Specifically Speech-To-Text), these phonemes are converted into a string of the approximated request, this is kept within a JSON file which also contains extra information about the user, the request and the session.The software receives an audio request from a user, processes the sound into phonemes, the building blocks of language.In recent years the scope of how you can engage with an assistant is expanding and evolving, but the crux of the technology is natural language in, lots of computation, natural language out. It receives a voice command and returns an answer in audio format. ‘today’, ‘now’, ‘when I get home’.Ī voice assistant is a piece of software capable of NLP (Natural Language Processing). The pieces of contextual information within an utterance, that helps the skill fulfill an intent, e.g. The word or phrase used to start a voice assistant listening, e.g. Intended action for the skill to fulfill, what the user wants the skill to do in response to what they say. Understanding Voice Jargon ( Large preview) KeywordĪ voice application, which can fulfill a series of intents Both have seen a massive rise in uptake over the last decade thanks to advances in Natural Language Processing (NLP). This key difference in using human language makes CUI more natural for people it requires little knowledge and puts the burden of understanding on the device.Ĭommonly CUIs comes in two guises: Chatbots and Voice Assistants. A GUI requires humans to learn its specific syntaxes of the interface (think buttons, sliders, and drop-downs). It is tipped to be a more natural interface for the general public than the Graphic User Interface GUI, which front end developers are accustomed to building.
