DuplexJev system enables frozen LLMs to hear beyond transcripts

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced DuplexJev, a novel system designed to improve the efficiency of full-duplex voice agents. Instead of traditional slow decoding, DuplexJev processes Automatic Speech Recognition (ASR) encoder hidden states through a small connector into a frozen Large Language Model (LLM). This allows the system to answer multiple decisions about eight utterances in approximately 0.1 seconds, significantly faster than previous methods. The system also demonstrates an enhanced ability to discern speaker emotion and gender, achieving 90% accuracy, and is made available with released weights and a training pipeline. AI

IMPACT Enhances voice agent efficiency and capabilities by enabling frozen LLMs to process speech decisions rapidly and understand non-transcriptual cues.

    Batched Speech Decisions Without Decoding: Single-Token Supervision Lets a Frozen LLM Hear Beyond the Transcript

    Full-duplex voice agents make many small, closed decisions, which current systems answer by slow autoregressive decoding. We propose DuplexJev, which feeds ASR-encoder hidden states through a small connector into a frozen LLM and reads each question as a single-token distribution…
