We formerly proposed a new segment quantization method named LZSQ, which is a modified version of the LZ coding, so that it can be applied to a continuous information source. In this paper, LZSQ is applied to a vocoder-type speech coder for reducing its bit rate, by removing temporal redundancy in coding parameters, while preserving the quality of coded speech.
In this paper, LZSQ is applied to six coding parameters of the MELP coder, which is one of the standardized vocoder-type speech coders operating at 2.4kbit/s, to reduce its bit rate as lower as possible. As the result, the total bit rate was reduced to about 1.57kbit/s. |
