- "A DSP-based modular architecture for Noise Cancellation and Speech Recognition".
- 1998 IEEE Int. Symposium on Circuits and Systems, ISCAS'98
- Monterey, California, USA, 31-May/3-June, 1998
- Through the present paper the architecture of a low-cost Hardware Building
Block (HBB) Board for Signal Processing is presented. An overview of the algorithms
to be supported by the HBB is followed by a brief presentation of the low-cost hardware
platform based on the TMS320C31, interfacing with a host computer through a PCI bus.
A description of the modular solutions based on this board for Isolated Word Speech
Recognition in Noisy Environments is also given. Measurements of the real-time performance
of the card and several Noise-Canceling experiments are also shown. Applications of the
proposed architecture may be found in the field of Speech Training, Language Acquisition,
Phonetics, and others related.
