The device’s built in microphone parses a user’s voice to be registered using natural language processing (NLP). The requests made by users are stored in data centres, which aid in the service delivery to the software’s users. Based on a user’s request history, digital assistants are now using pre-existing information to deliver services to users with higher accuracy. For example, “several times a day, Amazon uses the entire stack of Alexa queries to educate its A.I. about dialects and casual speech.”<ref>Moynihan, T. (2016, December 5).

   <p>Generally, voice activated digital assistants are constantly operating at a low processing rate until a key word is heard to notify the DA that a request is about to be made. For example, Google Home listens to its surroundings until the words “Ok Google” are said aloud. Digital assistants then translate a user’s proceeding commands into text that is analyzed by multiple algorithms to execute a task. These algorithms break up the requests into key parts, which make it easy to send emails, messages, or store records.</p>

(2019, September 6). Natural-language generation. Retrieved from en.wikipedia.org: https://en.wikipedia.org/wiki/Natural-language_generation</ref>. NLP deals with how to write computer programs to collect and process large amounts of natural language data. This can be a difficult task when some languages like Japanese and Chinese use characters that represent words and letters with no spaces between which makes it harder for the computer to understand what’s being said. It is easier in languages like English to identify words since they are almost always separated by a space. Another challenge is when the same word can be used as a different part of the sentence (noun, verb, etc). For example, you can turn on a light (noun), something can be light (adjective) (not heavy), you can light a candle (verb).</p>
