StreamSpeech: A Direct Simul-S2ST Speech-to-Speech Translation Model that Jointly Learns Translation and Simultaneous Policy in a Unified Framework of Multi-Task Learning

Practical Solutions for Simultaneous Speech-to-Speech Translation Challenges

Introduction

Large Language Models (LLMs) are vital for low-latency communication in scenarios like international conferences and live broadcasts.

Challenges with Current Methodologies

Existing methods for simultaneous speech-to-speech translation face challenges with error propagation and joint optimization.

StreamSpeech Solution

StreamSpeech tackles these challenges with a direct SimulS2ST model that integrates translation and policy learning through multi-task learning.

Key Components of StreamSpeech

StreamSpeech’s architecture includes a streaming speech encoder, a simultaneous text decoder, and a synchronized text-to-unit generation module, along with a HiFi-GAN vocoder for speech synthesis.

Performance of StreamSpeech

StreamSpeech outperforms existing models in both offline and simultaneous S2ST tasks, showing improved translation quality and reduced latency.

Advantages of StreamSpeech

StreamSpeech offers a direct approach, reducing error accumulation and improving overall performance in SimulS2ST tasks.
