NLP is the field of using computer science and AI to process and analyze natural language data and then make machines able to interpret it as humans do. During the 1980s, when this concept started to get hyped, language processing systems were designed by hand coding a set of rules. Later, following increases in calculation power, a different approach, mostly based on statistical models, replaced the original one. A later ML approach (supervised learning first, also semi-supervised or unsupervised at present time) brought advances in this field, such as voice recognition software and human language translation, and will probably lead to more complex scenarios, such as natural language understanding and generation.
Here is how NLP works. The first task, called the speech-to-text process, is to understand the natural language received. A built-in model performs speech recognition...
