LLMs Can Now Talk in Real-Time with Minimal Latency: Chinese Researchers Release LLaMA-Omni2, a Scalable Modular Speech Language Model

2025-05-06 AI Summary: Researchers at the Institute of Computing Technology, Chinese Academy of Sciences, have introduced LLaMA-Omni2, a family of speech-capable large language models (SpeechLMs) now available on Hugging Face. This research focuses on creating a modular framework enabling real-time spoken dialogue through the integration of speech perception and synthesis with language understanding. Unlike previous cascaded systems, LLaMA-Omni2 operates in an end-to-end pipeline while maintaining modular interpretability and low training cost. The models range from 0.5B to 14B parameters and are built upon the Qwen2.5-Instruct series.

The architecture comprises a Speech Encoder utilizing Whisper-large-v3 to transform speech into token-level acoustic representations, a Speech Adapter processing encoder outputs with a downsampling layer and feed-forward network, the core Qwen2.5 models for reasoning, and a Streaming TTS Decoder converting LLM outputs into speech tokens using an autoregressive Transformer and generating mel spectrograms via a CosyVoice2-inspired causal flow matching model. A gating mechanism fuses LLM hidden states with textual embeddings before speech synthesis, enhancing contextual fidelity. The system employs a read-write strategy, generating W speech tokens for every R tokens produced by the LLM, facilitating synchronized textual and acoustic generation and minimizing latency.

Empirical testing indicates that R=3 and W=10 provides an optimal balance between latency (~583 ms), alignment (ASR-WER: 3.26), and perceptual quality (UTMOS: 4.19). Despite training on a relatively compact dataset of 200K multi-turn speech-to-speech dialogue samples synthesized from instruction-following text datasets (Alpaca, UltraChat), utilizing diverse voices and a consistent output voice generated by FishSpeech and CosyVoice2, the models achieve competitive performance. Training proceeds in two stages: initially optimizing the speech-to-text and text-to-speech modules independently, followed by fine-tuning the speech-to-speech generation path, including the gating and decoding components. Benchmark results demonstrate that LLaMA-Omni2-14B consistently outperforms all baselines across tasks. Component analyses reveal that the gating mechanism’s removal increases ASR-WER and reduces speech quality, confirming its role in aligning textual and contextual signals. Furthermore, initializing the TTS model from Qwen2.5 and fine-tuning in a streaming setup yields the best performance, while training from scratch fails to converge effectively. The study highlights that multi-turn dialogue data is more effective than single-turn data for training speech interaction capabilities, with performance plateauing around 200K samples.

The article emphasizes the feasibility of achieving high-quality, low-latency spoken interaction with LLMs without extensive pretraining on massive speech corpora. LLaMA-Omni2’s modular architecture and autoregressive streaming synthesis offer a practical pathway for real-time speech applications.
