‘Digital Assistants’ demystifies the technology behind AI-powered assistants like Siri and Alexa, revealing how voice commands are transformed into actions. It explores the evolution of voice recognition, from early speech processing attempts to modern deep learning breakthroughs. A key insight is that understanding meaning, or user intent, is what distinguishes today’s digital assistants, emphasizing the shift towards genuine human-computer interaction.
The book progresses by first introducing core concepts like speech processing and natural language understanding. It then dedicates chapters to the components of a digital assistant, such as acoustic modeling and dialogue management, and examines ethical implications like data privacy and algorithmic bias. Finally, it explores diverse applications in healthcare and education. This approach provides a comprehensive overview of the technology while also exploring its ethical considerations.
A unique aspect of the book is its focus on the semantic layer, going beyond speech recognition to explore how these systems infer meaning and context. By examining the linguistic nuances of human speech and the cognitive processes involved in understanding natural language, ‘Digital Assistants’ offers a holistic perspective on this rapidly evolving technology and its impact on our daily lives.
