Cognitive Computing with IBM Watson

By: Rob High, Tanmay Bakshi

Overview of this book

Cognitive computing is rapidly becoming a part of every aspect of our lives through data science, machine learning (ML), and artificial intelligence (AI). It allows computing systems to learn and keep on improving as the amount of data in the system increases. This book introduces you to a whole new paradigm of computing – a paradigm that is totally different from the conventional computing of the Information Age. You will learn the concepts of ML, deep learning (DL), neural networks, and AI with the help of IBM Watson APIs. This book will help you build your own applications to understand, and solve problems, and analyze them as per your needs. You will explore various domains of cognitive computing, such as NLP, voice processing, computer vision, emotion analytics, and conversational systems. Equipped with the knowledge of machine learning concepts, how computers do their magic, and the applications of these concepts, you’ll be able to research and apply cognitive computing in your projects.

Chapter 4. This Is How Computers Speak

Ifyou've been around Siri, Alexa, or any number of other devices, including most modern cars and TVs, you will know that computers can speak and listen. For example, you can use Alexa to order more dog food, ask Siri about the weather outside, or even talk to your car to get navigation guidance to your next appointment. They do this through what we refer to as speech synthesis and speech recognition. IBM has been at the forefront of this technology for decades.

This technology was first introduced by IBM in a product called VoiceType in 1997, and then in a more general product called ViaVoice in 1999. Later, that same technology was licensed through ScanSoft, which then became Nuance. There is a useful library of information on the science of speech processing available at

Over the years, IBM has continued to enhance speech technology to leverage deep learning models, and now...
