Abstract

|
|
In this paper, we make an experiment on speech recognition systems with barging--in and non-barging-in utterances. Barging-in capability, with which we can say voice cgmmands while voice announcement is coming out, is one of the important elements for practical speech recognition systems, Barging-in capability can be realized by echo cancellation techniques basedd on the LM (least-mean-square) algorithm. We use three kinds of telephone interface boards with barging-in capability, which are respectively made by I ialogic Company, Natural Microsystems Company and Korea Telecom. Speech database was made using these three kinds of hoards. We make a comparative recognition experiment with this speech database.
