abstract = "A combined quantization-interpolation of speech LSP parameters for very low bit rate coding of speech is proposed. To utilize the linear dependency between successive LSP frames, the proposed algorithm attempts to locate the frames where there is a significant spectral change; these frames are encoded by vector quantization. The remaining frames are reconstructed by linear interpolation between the vector quantized frames. A two-pass algorithm is used to couple the quantization and interpolation operations. Simulation results for the performance of the combined quantization-interpolation approach indicate that at rates below 350 bps (for coding the spectral parameters), the proposed scheme outperforms the multi-frame coding scheme of Kemp et al. The effect of maximum delay on the overall performance is studied and some discussion on the performance of the proposed system over noisy channels along with preliminary simulation results are provided.",
