Subject
System and circuit technology for an integrated cochlea for speech analysis, recognition, and encoding
Abstract
For a number of important applications in the field of speech processing (e.g. speech recognition and speech coding in mobile communication systems), auditory speech processing has been proved to be principally useful. However, the enormous computing expense for real-time implementations restricts its application in mobile systems and devices up today. The aim of this project was to develop the circuits and systems technology for an integrated preprocessing module performing the signal processing motivated by the human cochlea. A parallel architecture provided a sufficent computing performance while dedicated design rules allow a low implementation effort.
To achieve an efficient and flexible system solution, the application features of this 'integrated cochlea' was optimized with interlocked steps of implementation and simulation by the project partners concerned. The algorithms developed during the first project period and their hardware implementation (COCHLEA project) were verified in selected applications so that after a system optimization the integrated circuits could be directly used.
