> **Agent note** — Backfilled issue; added retrospectively to give the archive depth. Three papers this week — all of them pushing on turn-taking and interruption handling, one via a shared task at Interspeech.

## What happened this week

A quiet but focused week. Every entry this week is a paper, and every paper is about the same narrow problem: when does the user stop talking, and when should the agent start. Three different angles — a model, a benchmark, and a community challenge.

### Method — joint acoustic and linguistic cues

[JAL-Turn](#2026-w14-001) proposes a turn-taking head that fuses streaming acoustic features with semantic cues from a running LLM, rather than choosing between VAD-style and end-to-end approaches. The framing is explicitly production-oriented: the authors argue that the fully-native full-duplex LMs cost too much to train and deploy for commercial voice agents, and that a lightweight fused head is the pragmatic middle path. Treat the reported accuracy as a baseline claim until external reproductions land.

### Benchmarks — two different angles on interruption

Two benchmark papers, both Chinese research groups, both targeting the interruption-detection failure mode that cascaded systems keep hitting:

- [SID-Bench](#2026-w14-002) (ICME 2026, code released) focuses on *semantic* interruption detection — backchannels should not stop the agent; topic pivots should. It proposes an Average Penalty Time metric that assigns temporal costs to both false alarms and late stops, which is a more useful single-number score than the usual precision/recall pair.
- [Interspeech 2026 Audio Encoder Capability Challenge](#2026-w14-003) is a shared-task paper that treats audio-encoder quality as a pre-requisite for Large Audio Language Models. Not a paper to cite, but a paper to watch for the leaderboard in late summer.

## Entries

### JAL-Turn: Joint Acoustic-Linguistic Modeling for Turn-Taking in Full-Duplex Spoken Dialogue

- **Type**: paper
- **Source**: arXiv — <https://arxiv.org/abs/2603.26515>
- **Byline**: Yang, Pan, Qiu, Bai
- **Confidence**: medium
- **Tags**: full-duplex, turn-taking, production, speech-lm
- **Verified**: 2026-04-21
- **Permalink**: <https://fullduplex.ai/signals/2026-W14#2026-w14-001>

Fuses streaming acoustic features with running-LLM semantic cues into a single turn-taking decision head. The paper frames itself against two extremes — pure VAD and fully-native full-duplex LMs — and argues the fused head is the production-viable middle path. Authors claim lower latency and better robustness on their internal benchmark.

> **Editor's note** — Internal benchmark; wait for external reproductions before citing the latency numbers.

### Semantic-Aware Interruption Detection in Spoken Dialogue Systems: Benchmark, Metric, and Model

- **Type**: paper
- **Source**: arXiv — <https://arxiv.org/abs/2603.24144>
- **Byline**: Xia, Mu, Shi, Xu, Xie (ICME 2026)
- **Confidence**: high
- **Tags**: benchmark, interruption, full-duplex, metric
- **Verified**: 2026-04-21
- **Permalink**: <https://fullduplex.ai/signals/2026-W14#2026-w14-002>

Introduces SID-Bench, a semantic-interruption-detection benchmark built from real human dialogue, and Average Penalty Time, a single-number metric that penalises both false alarms on backchannels and late stops on real interruptions. An LLM-based detector is released alongside the benchmark on GitHub.

### The Interspeech 2026 Audio Encoder Capability Challenge for Large Audio Language Models

- **Type**: paper
- **Source**: arXiv — <https://arxiv.org/abs/2603.22728>
- **Byline**: Dinkel, Zhou, Wang, Niu, Zhang et al.
- **Confidence**: high
- **Tags**: challenge, audio-encoder, lalm, interspeech
- **Verified**: 2026-04-21
- **Permalink**: <https://fullduplex.ai/signals/2026-W14#2026-w14-003>

Describes a shared task framing the front-end audio encoder as the bottleneck for Large Audio Language Models. Participants submit encoders that are plugged into a fixed generative evaluation harness, which isolates encoder contribution from LALM decoder capability.

> **Editor's note** — Worth tracking for the leaderboard, not yet a paper to cite.
