<p>PURPOSE:To generate outputs according to coincidence and dissidence between the features of an individual voice and those of a voice input by previously storing the features of the individual voice. CONSTITUTION:A voice input via microphone 1 is sampled by sampling circuit 3 and features of voices by individuals are extracted by frequency analyzer 4. The features of individual sounds registered by individuals are stored in memory unit 14. For example, when key 16 of a door is to be unlocked, an individual name is input by keyboard 11 to attain access to the feature of a registered voice. Then, they are collated with the features of the voice input via microphone 1 by CPU12 and when the both agree with each other, a coincidence pulse is output to electromagentic lock 16.</p> |
