With continued reference to FIG. 2, a flow 200 of one embodiment of an audio playback method according to the present application is shown. The audio playing method comprises the following steps:
In this embodiment, an audio playing method execution main body (for example, the server or the terminal shown in fig. 1) may obtain the audio to be played in response to receiving an audio playing instruction or in response to some playing setting. The audio to be played may include audio to be played while the user is engaged in an entertainment activity such as listening to music, watching video, or playing a game.
In this embodiment, the executing entity may determine whether the audio to be played acquired in step 201 includes an abnormal segment, where the abnormal segment is an abnormal sound segment, and may include various dissonant sound segments, such as sounds with too large volume, and segments of annoying sounds such as glaring or unintelligent words, for example. The abnormal fragments can be detected by a preset abnormal voiceprint recognition library or a pre-trained abnormal voiceprint recognition model, and since the voiceprints also belong to the category of images, the abnormal fragments can be obtained by training by referring to a training method of a common image recognition model. In addition, since the voiceprint can be regarded as a waveform, the abnormal voiceprint can be identified by setting upper and lower limits of the waveform and the like.
In some optional implementations of this embodiment, determining whether the audio to be played includes an abnormal segment includes: determining whether the audio to be played can be played through the earphone; and responding to the determination that the audio to be played is played through the earphone, and determining whether the audio to be played comprises an abnormal segment. In this implementation manner, the execution main body may determine whether the audio to be played will be played through the earphone by detecting whether the terminal is connected to the earphone and/or by determining whether the user wears the earphone through hardware devices such as the earphone.
Because for the situation of playing audio through the loudspeaker, the influence of hearing the abnormal segment is more direct when the user wears the earphone, and the damage to the hearing ability or the experience of the user is larger, therefore, in the implementation manner, before determining whether the abnormal segment is included in the audio to be played, it is determined whether the audio to be played can be played through the earphone, and after determining that the audio to be played can be played through the earphone, it is determined whether the abnormal segment is included in the audio to be played, so that the detection of the abnormal segment is more accurate, and the audio playing efficiency is further improved.
In some optional implementations of this embodiment, determining whether the audio to be played includes an abnormal segment includes: acquiring a voiceprint to be played by audio; and determining whether the acquired voiceprints comprise abnormal voiceprints or not through a pre-established abnormal voiceprint recognition library. Voiceprint (Voiceprint) is the spectrum of sound waves carrying verbal information displayed with an electro-acoustic instrument. In this implementation manner, the abnormal voiceprint recognition library may store information that can determine the abnormal voiceprint, such as the abnormal voiceprint itself and/or the characteristics of the abnormal voiceprint, and the execution main body may determine whether a voiceprint fragment in the voiceprint to be played matches with information in the abnormal voiceprint recognition library that is established in advance. According to the implementation mode, the abnormal voiceprint recognition library is established in advance, so that whether the acquired voiceprints comprise the abnormal voiceprints can be determined more comprehensively and in an individualized mode.
In some optional implementations of this embodiment, the abnormal voiceprint recognition library comprises a recognition library established via: and carrying out statistical storage on the voiceprints of the common noise and the preset abnormal sound. In this implementation manner, the voiceprints of the common noise and the preset abnormal sound can be directly stored, and the common characteristics of the voiceprints of the common noise and the preset abnormal sound can be counted and stored to obtain the abnormal voiceprint recognition library. The preset abnormal sound may include an abnormal sound set by a user and/or an application provider.
In this embodiment, the executing entity may perform, in response to determining that the audio to be played includes the abnormal segment in step 202, optimization processing on the abnormal segment included in the audio to be played to obtain an optimized audio. The optimization processing may include volume reduction and/or replacement using preset audio content, or may perform more personalized optimization processing according to a difference of the abnormal segment or a difference of the user, for example, volume reduction processing is performed on an abnormal segment with too large volume, tone reduction processing is performed on an abnormal segment with sharp ears, deletion processing is performed on an abnormal segment repeated for many times, and replacement processing is performed on an abnormal segment of the inexplicable language.
In some optional implementation manners of this embodiment, optimizing an abnormal segment included in the audio to be played to obtain an optimized audio includes: and carrying out volume reduction on the abnormal segment included in the audio to be played and/or replacing the abnormal segment by using preset audio content. The execution main body can reduce the volume to a range comfortable for human ears, and the preset audio content can comprise common audio such as 'drop' sound or the like or can use audio content set by a user. According to the implementation mode, the abnormal segment can be optimized rapidly by reducing the volume and/or replacing the preset audio content, and the audio playing efficiency is further improved.
And step 204, playing the optimized audio.
In this embodiment, the execution subject may play the audio obtained by optimizing the abnormal segment included in the audio to be played in step 203.
