Abstract
A speed up speech recognition search method is provided wherein the number of HMM states is determined and a microslot is allocated for Hidden Markov Models (HMMs) below a given threshold level of states. A macroslot treats a whole HMM as a basic unit. The lowest level of macroslot is a phone. If the number of states exceeds the threshold level a microslot is allocated for this HMM.
Claims9
A method of speech recognition comprising the steps of:
- providing input speech;
- providing HMM models;
- and
- recognizing input speech by searching said HMM models in a search network of slot units to interpret the speech wherein said slot units are determined by determining the number of HMM states and allocating a macro slot for HMMs below a given threshold of states, wherein said macro slot treats a whole HMM as a slot unit.

A method of speech recognition comprising the steps of:
- providing input speech;
- providing HMM models;
- and
- recognizing input speech by searching said HMM models in a search network of slot units to interpret the speech wherein said slot units include slot units greater than a speech frame when the number of HMM states are below a given threshold of states.
