It realizes speech recognition using an isolated word recognition method (phrase recognition method).
When you select one phrase from the pre-registered phrases and input it via voice, the recognition engine (voice recognition LSI) compares it with the group of phrases in the database (training data) and calculates the index assigned to the closest phrase along with its likelihood value. You can choose one of three types of host serial interfaces for the connection with the host.
