Natural Language Processing in Everyday Applications Natural language processing (NLP) helps computers understand and use human language. It powers many apps you use every day, often in ways you do not notice. From spell checkers to voice assistants, NLP makes language smart and helpful. Text input and search are common places where NLP shows up. When you type on a phone or computer, NLP predicts your next word and fixes mistakes. Auto-correct, autocomplete, and smart replies rely on models that learn from language patterns. In email clients or chat apps, NLP can summarize long messages or pull out key ideas so you can skim quickly. It also helps search systems understand questions, so you find the right information faster. ...

Speech Recognition and Synthesis Techniques and Applications Speech recognition turns spoken language into text, while speech synthesis converts text into spoken words. Together, they power voice assistants, accessibility tools, and real-time transcription. Modern systems adapt to different voices, languages, and environments through neural networks trained on large data sets. Techniques in recognition Early systems used hidden Markov models with Gaussian mixtures. Since then, deep neural networks have transformed the field. Today, end-to-end models combine acoustic and language tasks using CTC or attention, or rely on Transformer architectures. Key ideas include robust feature extraction (spectrograms, MFCCs), data augmentation, and streaming inference for live use. ...
