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

Understand

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 realistic deepfake speech, making it easier to mimic an individual's voice and spread misinformation.
• We refer to this emerging deepfake speech generated by CoSG systems as CodecFake.
• Detecting such CodecFake is an urgent challenge, yet most existing systems primarily focus on detecting fake speech generated by traditional speech synthesis models.
