| # DuplexCascade: Full-Duplex Speech-to-Speech Dialogue with VAD-Free Cascaded ASR-LLM-TTS Pipeline and Micro-Turn Optimization |
|
|
| This repository provides the model for **DuplexCascade**, a full-duplex speech-to-speech dialogue system built on a cascaded ASR-LLM-TTS pipeline with **VAD-free interaction** and **micro-turn optimization**. |
|
|
| The backbone large language model is [Qwen2-7B-Instruct](https://huggingface.co/Qwen/Qwen2-7B-Instruct), which was further fine-tuned for our duplex dialogue setting. |

|
| ## Model Description |
|
|
| DuplexCascade is designed for full-duplex spoken dialogue, enabling more natural interaction through: |
|
|
| - A cascaded **ASR-LLM-TTS** pipeline |
| - **VAD-free** dialogue control |
| - **Micro-turn optimization** for smoother turn-taking behavior |
|
|
| This model is obtained by fine-tuning [Qwen2-7B-Instruct](https://huggingface.co/Qwen/Qwen2-7B-Instruct) for the full-duplex dialogue setting. |
