Abstract

The GPT-4o represents a significant milestone in enabling real-time interaction with large language models (LLMs) through speech, its remarkable low latency and high fluency not only capture attention but also stimulate research interest in the field. This real-time speech interaction is particularly valuable in scenarios requiring rapid feedback and immediate responses, dramatically enhancing user experience. However, there is a notable lack of research focused on real-time large speech language models, particularly for Chinese. In this work, we present KE-Omni, a seamless large speech language model built upon Ke-SpeechChat, a large-scale high-quality synthesized speech interaction dataset consisting of 7 million Chinese and English conversations, featuring 42,002 speakers, and totaling over 60,000 hours, This contributes significantly to the advancement of research and development in this field.

KE-Omni Model Architecture

KE-Omni comprises three main components: a speech encoder, a large language model(LLM), and a speech decoder.

User: What's the best way to store different types of garden produce to keep them fresh for as long as possible?

Agent: To keep your garden produce fresh, it's best to store each type according to its specific needs. For example, leafy greens like lettuce and spinach should be kept in a cool, humid environment, while root vegetables like carrots and potatoes prefer a cooler, drier place. Berries and stone fruits do well in the refrigerator, but tomatoes should be stored at room temperature. Make sure to avoid storing ethylene-producing fruits like apples and bananas with sensitive vegetables, as this can cause premature ripening.
