Document Type and Number:
WIPO Patent Application WO/2019/076313
Kind Code:
A1
Abstract:
An audio recognition method, comprising: acquiring an audio file to be recognized (S100); extracting audio feature information of the audio file to be recognized, the audio feature information including audio fingerprints (S200); searching, in a fingerprint index database, audio attribute information matched with the audio feature information, the fingerprint index database including an audio fingerprint set in which invalid audio fingerprint removal has been performed on audio sample data (S300). As the audio fingerprint set in the fingerprint index database has been subjected to invalid audio fingerprint removal of audio sample data, the storage space of audio fingerprints in the fingerprint index database can be reduced, and the audio recognition efficiency can be improved. Further provided are an audio recognition device and a server.
