A method for accelerating neural network execution (4) in a speech recognition system, specifically for recognition of words contained in one or more subsets of a general vocabulary, involves the following steps. - at the recognition system initialisation phase, calculating the union of vocabulary subsets and determining the acoustic-phonetic units required for recognising the words contained in that union; re-compacting the neural network eliminating all the weighted connections afferent to computation output units corresponding to unnecessary acoustic-phonetic units; - executing only the re-compacted network at each instant of time. |
