Liberating LLM Capabilities in Full-Duplex Speech Models

arXiv:2606.07547v1 Announce Type: cross Abstract: Speech-based large language models are typically constrained to spoken replies, which limits their user-facing outputs to what can be verbalized and suppresses text-native capabilities such as code generation, structured analysis, and multi-step reasoning in realtime interaction, for tasks that require persistent, structured, and inspectable intermediate outputs. Existing work improves spoken reasoning or full-duplex turn-taking, but still treats text as a hidden intermediate state or a subordinate modality rather than a first-class output chan

Why this matters
Why now

Ongoing advancements in large language models (LLMs) and speech processing are enabling exploration into more integrated and versatile AI interaction modalities.

Why it’s important

This development addresses a critical limitation of current speech-based AI, unlocking text-native capabilities for real-time, inspectable human-AI interaction in complex tasks.

What changes

AI systems can now potentially leverage their full reasoning and generation capabilities in spoken conversations, moving beyond simple verbal responses to include structured outputs and multi-step processes.
