  • Method, apparatus, and terminal device for audio processing based on a matching of a proportion of sound units in an input message with corresponding sound units in a database
    Patent number: 11133009
    Abstract: Systems and methods are provided for improving audio processing by receiving an external input sound message during playing a first audio message; matching the external input sound message with a receiving message to obtain a matching result, wherein the receiving message is associated with the first audio message in content, wherein the matching is based on a proportion of sound units in the sound message that hit sound units in the receiving message; determining whether the matching result meets a threshold; and upon determining that the matching result meets the threshold, stop playing the first audio message.

  • Audio information retrieval method and device
    Patent number: 10127309
    Abstract: Embodiments of the present invention provide an audio information retrieval method and device. The method includes acquiring a spectrogram of an audio clip, extracting a local feature of at least one energy extreme point in the spectrogram to use as a local feature sequence of the audio clip, and conducting an audio information retrieval according to the local feature sequence of the audio clip to acquire audio information. Embodiments of the present invention reduce the probability of a missed match (e.g., false negative) and improve the accuracy of audio information retrieval.
