The invention discloses a voiceprint recognition method, device and equipment and a computer readable storage medium. The method comprises the following steps of acquiring voice information used for voiceprint recognition, and decomposing the voice information to obtain a first modal signal and a modal signal except the first modality; performing noise reduction processing on the first modal signal, and carrying out adding and reconstructing on the denoised first modal signal and the modal signal except the first modality to obtain the voiceprint information to be recognized; calculating the recognition degree of the voiceprint information to be recognized; and judging whether the voiceprint information to be recognized is the target voiceprint or not according to the recognition degree. The voiceprint recognition method provided by the invention improves the problem of inaccurate voiceprint recognition in the prior art.
