The current is input to the input end of the at least one stage of amplifier circuit prior to the current stage of amplifier circuit, and the quiescent operating current of the at least one stage of amplifier circuit prior to the current stage of amplifier circuit is controlled, so that the radio frequency power amplifier operates in a state in which the gain and the output power are stable.

Abstract: A voice enhancement method and apparatus, and a computer device and a storage medium. The voice enhancement method comprises: converting original voice information to obtain a digital voice signal (S10); obtaining a Hankel matrix on the basis of the digital voice signal (S20); performing a singular value decomposition operation on the Hankel matrix to obtain at least two singular values (S30); performing an inverse singular value decomposition operation on the at least two singular values to obtain a target voice signal (S40); and performing reduction processing on the target voice signal to obtain target speech information (S50). The voice enhancement method can effectively inhibit the noise interference, so as to improve the recognition accuracy of the target voice information in the voice recognition process.
