Hibiki's real-time advantage stems from its revolutionary multi-stream processing architecture. The system is designed with a parallel processing pipeline, where the input speech stream is instantly parsed into an intermediate representation while the target language generation module immediately starts the translation process. The core of the architecture contains:
- 8-16 RVQ (residual vector quantization) streams working in parallel
- Inter-stream synchronization mechanisms ensure semantic coherence
- Dynamic buffer management balances latency and accuracy
In real-world testing, the end-to-end latency of the 2B Parametric version is controlled within 800ms, and the 1B Lite version maintains a latency of less than 1.2 seconds even on mobile devices. This performance enables the system to achieve true conversation-level real-time translation, where users talk without pausing to get smooth output in the target language.
