Problems solved by technology

But the human voice in the actual program does not have such a wide bandwidth in a certain short period of time, most of them are only a small part of this frequency band, so the effect of highlighting the human voice cannot be achieved very well

Embodiment Construction

[0057] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the method for highlighting vocals in audio according to the present invention, and the method includes:

[0059] S10. Perform frame division processing on the audio signal to obtain each audio frame signal.

[0060] In this embodiment, the input audio signal can be monophonic, dual-channel or multi-channel. If it is detected that the audio signal is monophonic, the audio signal sampling data sequence is directly framed according to the preset frame length Processing; if it is two-channel, even multi-channel, then each way is all processed by the method of the present invention.

[0061] When the audio signal is divided into frames, for example, a frame with a duration of 1 ms can be used, and for a sampling rate of 48 kHz, ...

Abstract

The invention discloses a human voice highlighting processing method and device in an audio. The method comprises the following steps: carrying out framing processing on audio signals to obtain audio frame signals; grouping the obtained audio frame signals, wherein every N audio frame signals are grouped into one group, analyzing characteristics of frequency band range, frequency band energy, low-energy frame rate and zero-crossing rate of the audio frame signals in each group, and determining whether the audio frame signals in each group have human voice according to the analysis result of each group, N being a positive integer larger than 1; and if the audio frame signals in some group have human voice, carrying out band-pass filtering on the audio frame signals in the group to output a first audio signal obtained after filtering. According to the human voice highlighting processing method and device, the human voice can be accurately identified and the identified human voice is highlighted.

Description

technical field [0001] The present invention relates to the field of multimedia information, in particular to a method and device for highlighting human voice in audio. Background technique [0002] With the continuous development of multimedia technology, audio and video information plays an increasingly important role in people's work, style and entertainment. However, in some program sources on TV, there may be situations where the background sound is loud and the dialogue of the characters in the program is not clear enough, such as the dialogue of the characters in the sound of rain, the dialogue of the characters in the background of the gun battle, and the live interview in the news program. For this kind of problem, the existing TV has options of "clear voice" and "news" in "sound settings". When users watch such programs, they can manually open these options, but for some program sources, the effect of calling this function will be Worse, for example, for some musi...
