Abstract

To control an arbitrary system by speech recognition, it is proposed that speech recognition be implemented in the form of a predefined sequence of states, such that, upon recognition of an appropriate voice command, the system changes from one state to another state, and this change takes place in dependence on at least one speech recognition parameter. The speech recognition parameters can influence, for example, the so-called “false acceptance rate” (FAR) and/or the “false rejection rate” (FRR), which thus are set to state-specific values for the individual states, in order to achieve improved recognition accuracy.
