Problems solved by technology

For example, due to the noisy recording environment, various environmental noises that are difficult to remove are easily introduced into the recording signal
At the same time, the recording application requires that the user's voice be preserved as much as possible, and the traditional recording noise reduction algorithm is easy to misjudge the singing voice as noise, which in turn affects the recording sound quality.

Abstract

The present disclosure provides a method of processing an audio signal, a user terminal, an electronic device, a computer readable storage medium, and a computer program product. For example, intelligent noise reduction can be carried out on the recording (especially the recording containing singing), whether the current recording frame is used for recording human voice or not is intelligently determined, and different noise reduction schemes are adaptively applied to different segments in the recording based on the determined result; therefore, the human voice signal in the recording is reserved as much as possible while the environmental noise is suppressed.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence services, and more specifically relates to a method for processing audio signals, a user terminal, an electronic device, a computer-readable storage medium, and a computer program product. Background technique [0002] With the rapid popularization of short video and live broadcast business applications, recording applications (such as recording and sharing applications - online karaoke, etc.) are becoming popular among users. For example, a recording app can play an accompaniment, and the user can sing while listening to the accompaniment. The recording application can use a hardware device with a recording function (such as a mobile phone or a sound card device connected to a microphone) to record the user's singing voice to generate a recording signal. [0003] However, the recording signal contains not only human voice but also various noises (eg, environmental noise). For exa...
