Scaling Properties of Continuous Diffusion Spoken Language Models

Jason Ramapuram, Eeshan Gunesh Dhekane, Amitis Shidani +6

Speech-only spoken language models (SLMs) lag behind text and text-speech models in performance, with recent discrete autoregressive (AR) SLMs indicating significant computational…

Path-Constrained Mixture-of-Experts

Zijin Gu, Tatiana Likhomanenko, Vimal Thilak +2

Sparse Mixture-of-Experts (MoE) architectures route each token through a subset of experts at each layer independently. We propose viewing MoE computation through the lens of \emph…

Which Data Matter? Embedding-Based Data Selection for Speech Recognition

Zakaria Aldeneh, Skyler Seto, Maureen de Seyssel +8

Modern ASR systems are typically trained on large-scale pseudo-labeled, in-the-wild data spanning multiple domains. While such heterogeneous data benefit generalist models designed…

Closing the Gap Between Text and Speech Understanding in LLMs

Santiago Cuervo, Skyler Seto, Maureen de Seyssel +5

Large Language Models (LLMs) can be adapted to extend their text capabilities to speech inputs. However, these speech-adapted LLMs consistently underperform their text-based counte…

ChipChat: Low-Latency Cascaded Conversational Agent in MLX

Tatiana Likhomanenko, Richard He Bai, Zijin Gu +8

The emergence of large language models (LLMs) has transformed spoken dialog systems, yet the optimal architecture for real-time on-device voice agents remains an open question. Whi…

Omni-Router: Sharing Routing Decisions in Sparse Mixture-of-Experts for Speech Recognition

Zijin Gu, Tatiana Likhomanenko, Navdeep Jaitly

Mixture-of-experts (MoE) architectures have expanded from language modeling to automatic speech recognition (ASR). Traditional MoE methods, such as the Switch Transformer, route ex…

SpeakStream: Streaming Text-to-Speech with Interleaved Data

Richard He Bai, Zijin Gu, Tatiana Likhomanenko +1

The latency bottleneck of traditional text-to-speech (TTS) systems fundamentally hinders the potential of streaming large language models (LLMs) in conversational AI. These TTS sys…

What Makes the Preferred Thinking Direction for LLMs in Multiple-choice Questions?

Yizhe Zhang, Richard Bai, Zijin Gu +5

Language models usually use left-to-right (L2R) autoregressive factorization. However, L2R factorization may not always be the best inductive bias. Therefore, we investigate whethe…
