Model Details of EchoX-3B

EchoX: Towards Mitigating Acoustic-Semantic Gap via Echo Training for Speech-to-Speech LLMs

🐈‍⬛ Github | 📃 Paper | 📼 Online Demo (8B)

Model Description

EchoX is a Speech-to-Speech large language model that addresses the acoustic-semantic gap. This is the 3B version. By introducing Echo Training , EchoX integrates semantic and acoustic learning, mitigating the degradation of reasoning ability observed in existing speech-based LLMs. It is trained on only 10k hours of data while delivering state-of-the-art results in knowledge-based question answering and speech interaction tasks.

Key Features
  • Mitigates Acoustic-Semantic Gap in Speech-to-Speech LLMs
  • Introduces Echo Training with a Novel Three-Stage Pipeline (S2T, T2C, Echo)
  • Trained on Only 10k Hours of Curated Data, Ensuring Efficiency
  • Achieves State-of-the-Art Performance in Knowledge-Based QA Benchmarks
  • Preserves Reasoning and Knowledge Abilities for Interactive Speech Tasks
Usage

Load the EchoX model and run inference with your audio files as shown in the GitHub repository .
