1. Introduction

Transformers and their variants have achieved great success in speech processing. However, their multi-head selfattention mechanism is computationally expensive. Therefore, one novel selective state space model, Mamba, has been proposed as an alternative. Building on its success in automatic speech recognition, we apply Mamba for spoofing attack detection. Mamba is well-suited for this task as it can capture the artifacts in spoofed speech signals by handling long-length sequences. However, Mamba’s performance may suffer when it is trained with limited labeled data. To mitigate this, we propose combining a new structure of Mamba based on a dual-column architecture with self-supervised learning, using the pre-trained wav2vec 2.0 model. The experiments show that our proposed approach achieves competitive results and faster inference on the ASVspoof 2021 LA and DF datasets, and on the more challenging In-theWild dataset, it emerges as the strongest candidate for spoofing attack detection.

2. Setup Environment

You need to create the running environment by Anaconda. First, create and activate the environment:

conda create -n XLSR_Mamba python=3.10
conda activate XLSR_Mamba
