ZipCodec achieves ultra-low-frame-rate streaming speech coding

Researchers have developed ZipCodec, a novel neural audio codec designed for ultra-low-frame-rate streaming speech. Operating at 6.25 Hz with a bitrate of 0.80 kbps and a latency of 160 ms, ZipCodec significantly outperforms existing streaming codecs in reconstruction quality and downstream tasks. The system leverages large-scale WavLM distillation, a transformer-based architecture, and a scalar spherical quantizer, enabling real-time inference on consumer CPUs despite its 842 million parameters. AI

IMPACT This development could lead to more efficient and lower-latency speech generation and coding systems.

    ZipCodec: Ultra-Low-Frame-Rate Streaming Speech Coding

    arXiv:2609.11642v1 Announce Type: cross Abstract: Neural audio codecs are a fundamental component of modern speech generation systems. While recent codecs achieve increasingly low bitrates, reducing frame rate remains challenging, as each token must preserve more information whil…
