• Contact sales  Developing an Isolated Word Recognition System
in MATLAB  By Daryl Ning, MathWorks  Speech-recognition
technology is embedded in voice-activated routing systems at
customer call centres, voice dialling on mobile phones, and many
other everyday applications. A robust speech-recognition system
combines accuracy of identification with the ability to filter
out noise and adapt to other acoustic conditions, such as the
speaker’s speech rate and accent. Designing a robust speech-
recognition algorithm is a complex task requiring detailed
knowledge of signal processing and statistical modeling.  This
article demonstrates a workflow that uses built-in functionality
in MATLAB® and related products to develop the algorithm for an
isolated digit recognition system. The system is speaker-
dependent—that is, it recognizes speech only from one particular
speaker’s voice.  Classifying Speech-Recognition Systems  Most
speech-recognition systems are classified as isolated or
continuous. Isolated word recognitio
