Disentangling Linguistic and Paralinguistic Information with Routed Sparse Autoencoders

Beimnet Bekele Guta, Xiaoyu Yang, Guangzhi Sun +1

Self-supervised speech encoders contain linguistic and paralinguistic information in a shared, entangled representation space. We combine a TopK sparse autoencoder with route-speci…

SPEAR-Gen: Generation-Aware Pre-training for Unified Speech Representations

Xiaoyu Yang, Arthur Hinsvark, Antonios Alexos +3

Speech understanding and generation place different demands on speech representations, and existing models are typically optimised towards one capability or the other. To reduce th…

Text-Prompted CLAP: Learning Text-Conditioned Audio Representations via Contrastive Learning

Mohan Li, Rama Doddipatla, Philip C. Woodland

Contrastive Language-Audio Pretraining (CLAP) aligns text and audio in a shared embedding space, but encoding each modality independently limits its ability to model cross-modal se…

Spectral Allocation: Why Muon Outperforms Adam, and How to Improve Muon

Xiaodong Wu, Wenyi Yu, Chao Zhang +1

Orthogonal optimisers such as Muon can substantially accelerate large language model pretraining relative to Adam, yet the mechanism remains incompletely understood. We investigate…

SALMONN-2: Advancing General-Purpose Hearing Abilities with Self-Supervised Representations

Xiaoyu Yang, Xuenan Xu, Wenyi Yu +10

Recent audio large language models (ALLMs) are typically built upon audio encoders trained with large amounts of supervised data. Since self-supervised learning (SSL) audio encoder…

Multi-head Temporal Latent Attention

Keqi Deng, Philip C. Woodland

While Transformer self-attention offers strong parallelism, the Key-Value (KV) cache grows linearly with sequence length and becomes a bottleneck for inference efficiency. Multi-he…

SimulS2S-LLM: Unlocking Simultaneous Inference of Speech LLMs for Speech-to-Speech Translation

Keqi Deng, Wenxi Chen, Xie Chen +1

Simultaneous speech translation (SST) outputs translations in parallel with streaming speech input, balancing translation quality and latency. While large language models (LLMs) ha…

Transducer-Llama: Integrating LLMs into Streamable Transducer-based Speech Recognition

Keqi Deng, Jinxi Guo, Yingyi Ma +4

While large language models (LLMs) have been applied to automatic speech recognition (ASR), the task of making the model streamable remains a challenge. This paper proposes a novel…

Label-Synchronous Neural Transducer for E2E Simultaneous Speech Translation

Keqi Deng, Philip C. Woodland

While the neural transducer is popular for online speech recognition, simultaneous speech translation (SST) requires both streaming and re-ordering capabilities. This paper present…

Wav2Prompt: End-to-End Speech Prompt Generation and Tuning For LLM in Zero and Few-shot Learning

Keqi Deng, Guangzhi Sun, Philip C. Woodland

Wav2Prompt is proposed which allows straightforward integration between spoken input and a text-based large language model (LLM). Wav2Prompt uses a simple training process with onl…

FastInject: Injecting Unpaired Text Data into CTC-based ASR training

Keqi Deng, Philip C. Woodland

Recently, connectionist temporal classification (CTC)-based end-to-end (E2E) automatic speech recognition (ASR) models have achieved impressive results, especially with the develop…
