Abstract

The embodiment of the invention discloses a voice/music identifying method and voice/music identifying equipment, and relates to the technical field of audio; the voice/music identifying method and equipment are capable of enhancing the accuracy for identification of music. The voice/music identifying method comprises steps of: judging whether the energy change rate of the appointed amount of frames before the current frame and the energy of the current frame meet the condition of percussion music, and if so, determining an encoding mode of the current frame as a music mode. The embodiment ofthe invention is mainly applied to the voice/music identification process of audios, and the accuracy for the identification of the music can be enhanced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a voice / music recognition method and device. Background technique [0002] During the development of digital audio coding technology, since speech and music have different coding characteristics, it is usually necessary to adopt a coding technology suitable for their own characteristics when coding speech and music. For example, the coding technologies used for speech include GSM and CELPC, and the coding technologies used for music include MP3 and AAC. In recent years, the existing technology has proposed a voice-music joint coding technology. When using this technology to encode voice and music at the same time, it is first necessary to identify the input audio signal, that is, to identify whether the current audio signal is voice content or music. content, and then use different encoding methods for voice content and music content. Therefore, whether speech and music c...
