The shift from text-based chat to streaming voice and avatar interaction has exposed a critical gap in how conversational systems are measured. The Real-Time Conversational Agents (RTCA) workshop at NeurIPS 2026 highlights that standard offline metrics fail to capture the dynamics of live, multimodal dialogue. This workshop brings together researchers from speech, vision, language, and HCI to define new evaluation standards for systems that must listen, speak, and react under strict latency constraints.
The RTCA workshop identifies three intertwined research pillars: real-time generation, naturalness in interaction, and evaluation of live systems. The organizers argue that methods designed for offline generation—such as non-causal attention, large beam search, and multi-pass refinement—do not transfer to streaming deployments. Deployed agents still feel robotic because they exhibit stilted turn-taking, missing backchannels, monotone prosody, and awkward interruption handling. These are interactional qualities that per-utterance quality metrics cannot detect.
A core tension exists between system-level constraints and human-perceived quality. Hard latency budgets force trade-offs between model size, decoding strategy, and output fidelity. Incremental and speculative decoding improve responsiveness but may degrade semantic coherence or prosodic naturalness. The workshop explicitly calls for metrics that quantify perceived latency, turn-taking precision, backchannel appropriateness, and grounding success during live conversation. Perceptual studies and interactive Turing-style tests are proposed as complements to automatic metrics.
The submission tracks reflect this pragmatic focus. Full papers, short papers, and demo papers are all welcome, with a dedicated on-stage Conversational Agents Showcase for live deployed systems. Position papers and evaluation critiques are encouraged, signaling that the community recognizes the lack of shared vocabulary and benchmarks. The non-archival format allows rapid dissemination of work that might not fit traditional conference molds.
Safety and trust introduce additional evaluation dimensions unique to real-time agents. Deepfake risk, persuasion dynamics, and consent protocols must be assessed in interactive contexts where harm can unfold rapidly. Dataset submissions require ethics statements covering voice likeness consent and provenance. These requirements acknowledge that evaluation cannot be separated from deployment reality.
The closing panel—"What does naturalness mean, and how should we measure it?"—frames the central open question. There is no consensus yet on a unified metric suite. The field currently relies on a patchwork of turn-taking metrics, perceived latency scores, and subjective MOS ratings. The workshop aims to catalyze convergence toward standardized interactive benchmarks that capture the full multimodal, temporal, and social complexity of live conversation.
In summary, evaluating real-time conversational agents demands a paradigm shift from static utterance scoring to dynamic interaction measurement. The RTCA workshop provides a venue to debate, demonstrate, and eventually standardize these new metrics. Until such benchmarks mature, researchers must combine automatic streaming metrics with rigorous human evaluation in live settings.
