An Ultra-Low-Bitrate Neural Speech Codec with Plain-to-Pseudo Synergistic Vector Quantization
P2PSynCodec replaces residual vector quantization with a plain-to-pseudo synergistic scheme that transmits only one VQ codebook index and predicts the rest, cutting bitrate by a factor of four while preserving quality.
