An instrumental music detection method and apparatus, and a storage medium. The method comprises: acquiring audio to be tested (201); performing human voice separation processing on said audio to obtain an audio segment to be processed (202); then extracting audio features from said audio segment, the audio features comprising Mel features and human voice ratio features (203); inputting the audio features into a trained human voice detection network model (204); acquiring an output result of the trained human voice detection network model (205); and if determined, according to the output result, that said audio segment does not contain a human voice, then determining that said audio is instrumental music (206). The described method performs instrumental music detection on an audio segment separated from audio to be tested, without needing to perform detection on an entire song; the length of said audio is relatively short, and the method may improve the accuracy of instrumental music detection.
