Abstract: Models like GPT-4o enable real-time interaction with large language models
(LLMs) through speech, significantly enhancing user experience compared to
traditional text-based interaction. However, there is still a lack of
exploration on how to build speech interaction models based on open-source
LLMs. To address this, we propose LLaMA-Omni, a novel model architecture
designed for low-latency and high-quality speech interaction with LLMs.
LLaMA-Omni integrates a pretrained speech encoder, a speech adaptor, an LLM,
and a streaming speech decoder. It eliminates the need for speech
transcription, and can simultaneously generate text and speech responses
directly from speech instructions with extremely low latency. We build our
model based on the latest Llama-3.1-8B-Instruct model. To align the model with
speech interaction scenarios, we construct a dataset named InstructS2S-200K,
which includes 200K speech instructions and corresponding speech responses.
Experimental results show that compared to previous speech-language models,
LLaMA-Omni provides better responses in both content and style, with a response
latency as low as 226ms. Additionally, training LLaMA-Omni takes less than 3
days on just 4 GPUs, paving the way for the efficient development of
speech-language models in the future.
