AHAMask: Reliable Task Specification for Large Audio Language Models without Instructions

Yiwei Guo, Bohan Li, Hankun Wang +4

Although current large audio language models (LALMs) extend text large language models (LLMs) with generic acoustic understanding abilities, they usually suffer from prompt sensiti…

CodecSlime: Temporal Redundancy Compression of Neural Speech Codec via Dynamic Frame Rate

Hankun Wang, Yiwei Guo, Chongtian Shao +2

Neural speech codecs have been widely used in audio compression and various downstream tasks. Current mainstream codecs are fixed-frame-rate (FFR), which allocate the same number o…

Towards General Discrete Speech Codec for Complex Acoustic Environments: A Study of Reconstruction and Downstream Task Consistency

Haoran Wang, Guanyu Chen, Bohan Li +5

Neural speech codecs excel in reconstructing clean speech signals; however, their efficacy in complex acoustic environments and downstream signal processing tasks remains underexpl…

Unlocking Temporal Flexibility: Neural Speech Codec with Variable Frame Rate

Hanglei Zhang, Yiwei Guo, Zhihan Li +3

Most neural speech codecs achieve bitrate adjustment through intra-frame mechanisms, such as codebook dropout, at a Constant Frame Rate (CFR). However, speech segments inherently h…
