The first stage utilizes LiquidAI's LFM2-350M as a backbone for semantic and acoustic tokenization. This model converts input text into a sequence of compressed audio tokens, analyzing semantic meaning, syntactic structure, and prosodic cues to create high-level speech representations.
The second stage employs NVIDIA's NanoCodec as a highly optimized vocoder. This lightweight generative model converts audio tokens into continuous, high-fidelity audio waveforms with near-instantaneous processing, enabling real-time operation and low latency.
The two-stage architecture provides significant advantages in speed and efficiency. The backbone generates compressed token representations that are rapidly expanded into audio waveforms, bypassing computational overhead and resulting in extremely low latency suitable for interactive applications.
