となっていた。Since the conventional device is configured as described above, it is necessary to register the voice and registration number in the speaker verification device (4) in advance. It is registered as basic data based on the voice.However, when actually using intercoms at gates located in various places, the voice characteristics may deteriorate (distortion, S/N, etc.) depending on the performance of the microphone and the intercom line. This makes it difficult to extract stable feature quantities.For this reason, it is necessary to set a wide threshold for matching, resulting in an unreliable device.

ことができる。The entrance/exit control device of this invention uses a specific microphone to digitize and transmit the voice, which eliminates sound quality deterioration due to microphone performance and sound quality deterioration due to transmission line (type, distance), and provides stable voice data. It is possible to extract stable speech features (without fluctuations due to external factors) based on the above.
以下、この発明の一実施例を第２図と同一部分は同一符
号を付して示す第１図により説明する。Hereinafter, one embodiment of the present invention will be described with reference to FIG. 1, in which the same parts as in FIG. 2 are denoted by the same reference numerals.

るようになっている。In the figure, (6) indicates a microphone (5), a key (1) for inputting the recitation code, an A/D converter (γ) for converting analog audio into digital, and an output section (for outputting the recitation code and audio digital signal). The transmission device (2) receives the digital signal from this portable voice input device and sends it to the speaker verification device (4) at the center via the intercom line (8). It is designed to transmit information.
