Speech and audio processing has undergone a revolution in preceding decades that has accelerated in the last few years generating game-changing technologies such as truly successful speech recognition systems; a goal that had remained out of reach until very recently. This book gives the reader a comprehensive overview of such contemporary speech and audio processing techniques with an emphasis on practical implementations and illustrations using MATLAB code. Core concepts are firstly covered giving an introduction to the physics of audio and vibration together with their representations using complex numbers, Z transforms and frequency analysis transforms such as the FFT.
Later chapters give a description of the human auditory system and the fundamentals of psychoacoustics. Insights, results, and analyses given in these chapters are subsequently used as the basis of understanding of the middle section of the book covering: wideband audio compression (MP3 audio etc.), speech recognition and speech coding.
The final chapter covers musical synthesis and applications describing methods such as (and giving MATLAB examples of) AM, FM and ring modulation techniques. This chapter gives a final example of the use of time-frequency modification to implement a so-called phase vocoder for time stretching (in MATLAB).
Features
A comprehensive overview of contemporary speech and audio processing techniques from perceptual and physical acoustic models to a thorough background in relevant digital signal processing techniques together with an exploration of speech and audio applications.
A carefully paced progression of complexity of the described methods; building, in many cases, from first principles.
Speech and wideband audio coding together with a description of associated standardised codecs (e.g. MP3, AAC and GSM).
Speech recognition: Feature extraction (e.g. MFCC features), Hidden Markov Models (HMMs) and deep learning techniques such as Long Short-Time Memory (LSTM) methods.
Book and computer-based problems at the end of each chapter.
Contains numerous real-world examples backed up by many MATLAB functions and code.

Fully updated and revised, this seminal book explains and illustrates what photographs are, how they were made and used in the past and, more particularly, what their place is in the creative arts and visual communications world of today.
Paul Hill looks at photographs as modes of expression and explores the diversity of approaches taken when creating photographs and what these mean for a photographer’s practice and purpose. It emphasises the importance of contextualisation to the understanding of the medium, diving into the ideas behind the images and how the camera transforms and influences how we see the world. With an impressive collection of 200 full colour images from professional practitioners and artists, it invites us to consider the foundations of photography’s past and the digital revolution’s impact on the creation and dissemination of photographs today.
Essential reading for all students of photography, it is an invaluable guide for those who want to make a career in photography, covering most areas of photographic practice from photojournalism to fine art to personal essay.
