CodecFake+: Codec-Based Resynthesized Data as a Proxy for Detecting CodecFake Speech

Xuanjun Chen, Jiawei Du, Haibin Wu +8

With the rapid advancement of neural audio codecs, codec-based speech generation (CoSG) systems have become highly powerful. Unfortunately, CoSG also enables the creation of highly…

How Does Instrumental Music Help SingFake Detection?

Xuanjun Chen, Chia-Yu Hu, I-Ming Lin +8

Although many models exist to detect singing voice deepfakes (SingFake), how these models operate, particularly with instrumental accompaniment, is unclear. We investigate how inst…

Codec-Based Deepfake Source Tracing via Neural Audio Codec Taxonomy

Xuanjun Chen, I-Ming Lin, Lin Zhang +4

Recent advances in neural audio codec-based speech generation (CoSG) models have produced remarkably realistic audio deepfakes. We refer to deepfake speech generated by CoSG system…
