Abstract
An audio identification method and apparatus are disclosed within the technical field of audio processing technology. The audio identification solution includes obtaining an original pitch sequence of a to-be-identified audio, where the original pitch sequence is used to indicate a frequency of the to-be-identified audio at each time point. The audio identification solution further includes dividing the original pitch sequence into a plurality of pitch sub-sequences, respectively identifying the original pitch sequence and the plurality of pitch sub-sequences, and combining the identification results. In doing so, the audio identification solution obtains a final identification result by dividing a long pitch sequence into a plurality of short pitch sequences, thus respectively identifying the long pitch sequence and the plurality of short pitch sequences, and combining identification results.
