Abstract: Embodiments of this application provide a volume adjustment method and an electronic device. The volume adjustment method includes: receiving target volume used when a media playing device plays content; obtaining an audio signal, where the audio signal includes a first signal and a second signal, the first signal is a sound signal that is collected by a wearable device worn by a user and that is generated when the media playing device plays the content, and the second signal is a noise signal collected by the wearable device; determining adjusted volume based on the audio signal and the target volume; and sending the adjusted volume to a target device through a communication connection to the target device, where the adjusted volume is used to update volume used when the media playing device plays the content.

Abstract: A speech enhancement method includes determining a first spectral subtraction parameter based on a power spectrum of a speech signal containing noise and a power spectrum of a noise signal, determining a second spectral subtraction parameter based on the first spectral subtraction parameter and a reference power spectrum, and performing, based on the power spectrum of the noise signal and the second spectral subtraction parameter, spectral subtraction on the speech signal containing noise, where the reference power spectrum includes a predicted user speech power spectrum and/or predicted environmental noise power. Regularity of a power spectrum feature of a user speech of a terminal device and/or regularity of a power spectrum feature of noise in an environment in which a user is located are considered.
