Abstract
A method for coding speech at low bit rates is disclosed. As compared to the well known stochastic coding method, the method of the present invention requires substantially less computational resources. The reduction of required resources is achieved by utilizing a set of code sequences in which each code sequence is related to the previous code sequence. For example, each succeeding code sequence may be derived from the previous code sequence by removing one or more elements from the beginning of the previous sequence, and adding one or more elements to the end of the previous sequence.
