Research on Improved Speech Recognition Based on Whale Algorithm Isolated Words

Speech recognition is an internationally recognized and promising new technology. This paper studies the improved speech recognition based on whale algorithm isolated words. Firstly, the basic whale algorithm is introduced. U sing standard and improved whale algorithms, the BP neural network is optimized. Then the data are trained and learned respectively, and the recognition rate is compared. Finally the more suitable method for speech recognition of isolated words is determined. The self-built database experiments show that compared with the standard algorithm to optimize the BP neural network, the improved algorithm is helpful to improve the accuracy of speech recognition.
