| Abstract: | Speech recognition is an important research direction of Speech signal processing, which is related to physiology, psychology, linguistics, computer science and signal processing and many other fields. It is widely used in control, communications, digital products and other industries. This article describes a simple speech recognition algorithm. The main processes include pre-processing, endpoint detection, extraction of feature value and pattern matching. The amplitude is the standard in endpoint detection. The critical Eigen Value is used as eigenvector. DTW algorithm is used in pattern matching. Main design idea is to get the voice signal and match it with the stored pattern. A hardware system with TMS32OVCS402 chip as the core is used to implement this algorithm. |
