NemotronLabs VoiceChat: An Open Full-duplex Speech-to-Speech Model with Tool Calling Capabilities

The results demonstrate that full-duplex interaction, speech recognition and generation, general language capabilities, and external tool use can be integrated in a single open speech-to-speech model without sacrificing real-time conversational behavior.

Voice Memory for Agentic Speech Recognition

Voice Memory, a inference-only scheme for agentic speech recognition: at stream time, a frozen corrector reads a single per-domain memory and decides per utterance whether to act on the hypothesis or abstain and keep the 1-best, and transfers across corrector families and adds zero parameters to the inference path.

Enabling Streaming User Transcription in Full-Duplex Speech-to-Speech Models

This work proposes an efficient method to add streaming ASR capabilities to an existing duplex S2S model by introducing a lightweight ASR head in parallel to the agent text head, enabling real-time user transcription while preserving full-duplex conversational capabilities including turn-taking and barge-in handling.

JarvisBench: Always-on Intelligence Between Humans and Agents

This work proposes an always-on attention-coordination layer that mediates this interface and allocates human attention across one or more working agents, and introduces JarvisBench to evaluate both directions of this coordination.

Just A Rather Very Intelligent Spoken Agent

JarvisBench, a benchmark for measuring the dual value of mediation in long-horizon agent workflows, is introduced and preliminary results suggest that Jarvis-style mediation can provide trace-grounded responses to user questions and improve task performance when sparse user guidance is injected at appropriate moments.
