Embodiment Construction

[0071] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0072] For a highly robust audio fingerprint recognition method provided by an embodiment of the present invention, see figure 1 As shown, including steps 101-105:

[0073] Step 101: Obtain audio data to be identified, and perform preprocessing on the audio data to be identified to remove special signals, which include one or more of ringing tone, color ring tone, busy tone, and silence.

[0074] In the embodiment of the present invention, the audio data to be identified may specifically be audio data related to the calling tone or the called tone; taking the called tone as an example, there are many types of the called tone, generally at least 30 Various, by remov...

Abstract

The present invention provides a highly robust audio fingerprint identification method and system, wherein the method includes: acquiring audio data to be identified, and performing preprocessing on the audio data to be identified; Domain transformation and Bark domain transformation, using all subband energy as the original features of the audio data to be identified; modifying the original features, and using the modified original features as the robustness features of the audio data to be identified; according to the audio data to be identified The robustness of the data is used to model the voice fingerprint, and the audio fingerprint to be recognized corresponding to the audio data to be recognized is generated; the preset audio fingerprint library is loaded, and the audio fingerprint to be recognized is matched with the standard audio fingerprint in the audio fingerprint library. Identify the audio fingerprint to be recognized. The method uses the robustness feature to generate and match the audio fingerprint to be recognized, which can improve the robustness of the recognition process and make the recognition result more accurate.

Description

technical field [0001] The invention relates to the technical field of audio recognition, in particular to a highly robust audio fingerprint recognition method and system. Background technique [0002] At present, the audio fingerprint technology extracts the invariant features in the audio signal and uses them as a unique identifier to describe the signal. This feature is called an audio fingerprint. Audio fingerprint, as the core algorithm of automatic content identification technology, has been widely used in song identification, content monitoring, content deduplication, file identification and other fields. [0003] Audio fingerprint technology has the characteristics of content-based, less fingerprint data, and certain robustness against attacks, so it can better solve the problem of audio retrieval and matching. After the fingerprint technology was proposed, it has developed rapidly, and many technical solutions have been proposed, and good commercial applications ha...
