This invention discloses a method for enhancing the robustness of a voiceprint retrieval model, belonging to the field of voiceprint retrieval. The invention aims to provide a method to enhance the robustness of systems using deep learning to build speech retrieval models, helping the system maintain relatively good performance even when subjected to adversarial example attacks. First, during a retrieval process, the relevance of the search results is ranked, and relatively relevant speech is selected. Then, the query statement is denoised. Next, using the denoised query speech, a second query is performed among the previously selected relatively relevant speech, selecting the most relevant speech from this second query as the final query result. This invention provides a method to enhance the robustness of voiceprint retrieval models in deep learning-based voiceprint retrieval systems, helping the system operate more effectively.
