  The present invention relates to a voice recognition type voice guidance apparatus that answers requested guidance information by voice when a user requests provision of information by voice.

  As a voice utterance unit for the visually impaired, possess a portable wireless transmitter, handle the push button switch provided on the wireless transmitter, emit radio waves, and receive these radio waves at the radio receiver installed at the destination However, the radio receiver demodulates and identifies the signal contents, and automatically transmits a message from a speaker to guide a visually impaired person (see Patent Document 1) or a visually impaired person using a facility such as a public facility. When you have a card with a built-in transmitter that transmits a predetermined weak radio wave with a predetermined reachable range, and the person approaches the vicinity of a facility such as a toilet, the voice guidance system guides you to the facility by voice. A voice guidance system for automatically broadcasting information (see Patent Document 2) is known.

  The former is a method of obtaining guidance information by handling a push button when the person who owns the wireless transmitter wants to obtain information, and the latter is a method of automatically obtaining guidance information only by possessing the wireless transmitter. It is.

  However, although these methods can issue a request for obtaining guidance information to a user, they cannot issue a request for what information to obtain more actively. In short, the user is just waiting for the information given and has to walk around until the desired information is obtained.

  Furthermore, whether you want to obtain guidance information by handling a push button when you want to get information, or you can get guidance information automatically just by holding a wireless transmitter, voice guidance guidance at the destination Since the voice guidance information is broadcast when the device catches the radio wave emitted by the user, for example, in a place where two or more voice guidance devices are installed close to each other, Since guidance guidance information is broadcast all at once from the voice guidance and guidance device, it is extremely difficult to select or extract necessary information.

  Of course, the above-mentioned problems can be avoided by giving guidance to the broadcast time of the information of the guidance information broadcast from each guidance and guidance device, but the user must listen carefully to the broadcast contents. First, when the order of information you want is last, you must listen to the broadcast.

Also, voice guidance information is often shared within a certain area. For example, the same voice information information flows near the entrance and exit of the area, and the user knows where he is now. It was difficult.

The volume is adjusted by a volume adjustment knob 19. The portable device is not limited to the one shown in the figure, and a tie pin type microphone earphone can be used.

  An example in which a user searches for a destination point using the device of the present invention will be described below. For example, when the user M searches for a men's toilet in the facility, the user turns on the power switch 15 of the portable device 1 in the facility. When you want to receive information about the equipment in the facility at the entrance hall, for example, when you want to add a small one, you want to know the location of the men's toilet. Then talk to the wireless microphone 17 and ask, "Where is the men's toilet?" The voice is wirelessly transmitted as an information request signal through the antenna 24 of the portable device 1, and the information request signal is input from the antenna 24 to the voice recognition device 3. The voice recognition device 3 identifies the request content from the input information request signal, designates the specific voice information 5a to be provided with the specific guidance information and the guidance information as a response, and receives the guidance information from the voice voice part 5a. Is output by voice.

  This is exactly the same for the answer from the voice utterance unit 5b, 5c or 5d to the questions “Where is the girls' toilet?”, “Where is the reception counter?”, “Where is the telephone counter?”. Next, the operation of the speech recognition type speech utterance unit according to the present invention will be described with reference to the flowchart shown in FIG. In FIG. 4, the user utters a voice requesting to provide information toward the portable device (step 1). The voice is input to the voice recognition device (step 2). The speech recognition apparatus determines whether or not the input speech signal is a user request signal (step 3). If it is an information request signal, the input content is analyzed and the input speech is converted into text data ( (Hereinafter referred to as character information) and compared with the character information in the input voice data group (step 4). In the input voice data group of the voice data section, guidance information to be provided, in this embodiment, character information of destination names such as “Men's toilet”, “Women's toilet”, “Reception”, “Telephone” is stored. ing. If the destination location name of the input voice data group is included in the character information recognized by the voice recognition device, the character information of the destination location is extracted (step 5), and the corresponding destination location is output from the output voice data group. Take out the data. The data stored in the output audio data group is audio data such as “XX is here”. The extracted voice data outputs the contents of the information to be provided to the user through a voice utterance unit installed at the corresponding destination location (step 6). For example, voice guidance information is broadcast from a voice utterance unit installed in a men's toilet.

  FIG. 5 is an example in which the user reaches the destination location via several relay locations. A user at a station looks for a city hall. In this example, relay points P1, P2,... Are set at each intersection of the road from the station square to the city hall, and P4 is the city hall in front of the destination. Each relay point and destination is a place where a user's information request is issued, and at the same time a guidance providing place. Antennas 4a, 4b, 4c, and 4d and voice utterance units 5a, 5b, 5c, and 5d are installed in order at each relay point and destination, and an information request signal transmitted from the user's portable device is transmitted to each relay point and destination. The information request signal is received by the ground antenna and transmitted to the voice identification device together with the issued relay points P1, P2,... Or the position information of the destination P4.

  A command issued from the voice recognition device is transmitted to each relay point where the antenna is installed or a voice utterance unit at the destination, and the voice utterance unit receiving the command broadcasts guidance information in response to an information request. . In this embodiment, when a user who gets off the station goes through the station square and stands at the first relay point P1 at the station square intersection, he speaks to the portable device as “Where is the city hall”? Voice guidance information is broadcast from the voice utterance section 5a of “If you come from the station, please go straight across the pedestrian crossing”.

  Continue walking along the front of the station according to the guidance, and when you enter the next intersection, relay point P2, you will also hear "Where is the city hall". From the voice utterance unit 5b at the relay point P2, If you are, please go to the left. ” Because the content of the broadcast has changed, users can know that they are now at a new relay point. After that, turn left on the road according to the broadcast instructions, and go straight ahead and ask the question at the relay point P3. If there is a response, continue straight ahead to reach destination P4 and ask “Where is the city hall” in the same way, the voice utterance unit 5d responds to the question and says, “The city hall entrance is here.” It is broadcast that it reached.

  In the above embodiment, an example in which a city hall is selected as a destination is shown, but the provision procedure of guidance information is exactly the same even when another destination is selected. When another destination is selected by the user, the voice recognition apparatus recognizes the requested information from the voice data part by the voice recognition apparatus voice-recognizing the destination name keyword issued by the user. The voice guidance information necessary to reach the destination by extracting the data is provided.

  The guidance information is uttered not only from the voice utterance unit installed at the destination point and the relay point, but also from the speaker 18 of the portable device 1 shown in FIG. 3 by wirelessly transmitting a guidance information signal to the portable device 1. be able to. That is, in FIG. 6, the information request signal transmitted from the portable device 1 is received by the antenna 4 of the voice guidance device 2, and the guidance information signal as a response is built into the voice uttering unit 5 and the voice recognition device from the control unit 9. The guidance information is uttered from the voice utterance unit 5 at the relay point or the destination and is wirelessly transmitted from the transmission unit 20 through the antenna 4, and this radio wave is transmitted to the receiver of the portable device 1.
