Pressezitat
From the reviews:"Three techniques that can implement keyword spotting are described in this brief. ... The text is well written, with frequent references to relevant publications. The techniques and analyses are clearly presented and supported by appropriate diagrams. This brief should be of interest to practitioners in this area." (G. R. Mayforth, Computing Reviews, October, 2013)
