A voice recognition apparatus is provided which includes a first detection circuit for receiving an electric signal corresponding to voice. The first detection circuit detects a voice termination point representing a time at which the input of the electric signal corresponding to the voice is terminated based on the electric signal. The apparatus further includes a second detection circuit for determining a speech period, the speech period being a period in which the voice is uttered within a whole period in which the voice is input, based on the electric signal. In addition, the apparatus includes a feature amount extracting circuit for producing a feature amount vector, on the basis of a part of the electric signal corresponding to the speech period. A memory is provided for storing feature amount vectors for a plurality of voice candidates which are previously generated. The apparatus further includes a circuit for recognizing the input voice, by comparing the feature amount vector from the feature amount extracting circuit with each of the feature amount vectors of the plurality of voice candidates stored in the memory. The speech period is determined by a detection of a speech period start point representing a time at which an utterance is started and a detection of a speech period termination point representing a time at which the utterance is terminated.
