Abstract

PURPOSE:To facilitate a phone call in hand-free state by announcing a candidate close to a command voice when the command voice and a registered voice are dissident, using a confirmation switch so as to confirm a relevant party when the relevant party is found out thereby applying automatic dialing. CONSTITUTION:When a driver makes a phone call during driving, a registration command switch 4 is set to the position of the command and utters a name of an opposite party toward a microphone 5. A controller 3 retrieves the opposite party from the registered voice and the retrieved name of opposite party is announced from a speaker 7 built in a head rest 16. When the name is dissident, the controller 3 retrieves a candidate close to the commanded voice among other registered voices and announces them sequentially and discriminates whether or not a confirmation switch 6 is depressed. When a relevant party is announced among candidates announced sequentially from the speaker 7 at the ear, the driver depresses the switch 6. when the switch 6 is depressed, the controller 3 applies automatic dialing to the relevant opposite party.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a voice command type car telephone.

(Prior art and problems to be solved) When a driver communicates with the other party using the handset (receiver) of a car phone while driving a car, driving the car and operating the phone at the same time can cause problems for safe driving. It is preferable that the driver be able to operate the telephone without picking up the handset.

Therefore, we have a regular handset phone and a hands-free phone with a speaker and microphone placed on the instrument panel in front of the driver's seat, and when the driver uses the phone, he can switch to the hands-free phone.
2. Description of the Related Art Car telephones are known in which the driver selects and calls the other party's station by voice, and communicates with the other party using a microphone and a speaker.

A so-called voice-command car phone that uses voice to select or call the other party searches for the one that matches or most closely resembles the command voice from among a large number of registered voices, and displays the corresponding voice if one is found. If there is no command, for example, the message "Please try again" is displayed and the driver is requested to speak the command again.

By the way, currently, the command voice recognition rate is at most 8.
The range is 0 to 90%, and in some cases command voice may be requested many times, making it difficult to use.

The present invention has been made in view of the above-mentioned points. When the command voice and the registered voice do not match, a speaker built in the headrest of the driver's seat provides a plurality of approximate candidates from among the registered voices. To provide a voice command type car telephone that makes announcements sequentially and automatically dials a person by operating a confirmation switch when a corresponding person is found.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a voice command type car telephone that inputs a command voice and automatically dials when the voice matches a registered voice.
If the command voice and the registered voice do not match, a speaker built into the headrest of the driver's seat will announce several similar candidates from among the registered voices, and when a matching person is found. The configuration includes a control means for automatically dialing after confirmation using a confirmation switch.

(Function) When a command voice is input, the control means searches for the commanded party from among the registered voices, and announces the searched party from a speaker built into the headrest of the driver's seat.

If the announced name of the other party does not match the commanded name, a plurality of similar candidates are restored from among the registered voices and announced sequentially from the speaker.

When the confirmation switch is operated when there is a corresponding person, the control means automatically dials the confirmed party.

(Example) An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, the voice command type car phone l is
It is composed of a telephone main body 2 and a control device 3, and the telephone main body 2 is connected to the control device 3. Control device 3
A registration/command switch 4, a microphone 5, and a confirmation switch 6 are connected to the input side, and a speaker 7, an indicator 9, an audio No. 10, etc. are connected to the output side. Note that the speaker 7 is connected via a volume 8, so that the volume can be adjusted.

The control device 3 is equipped with a computer for voice recognition, and when the registration/command switch 4 is set to the registration side, the voice input from the microphone 5 is accepted and registered in the memory, and the registration/command switch 4 is set to the registration side. When set to the command side, it accepts the command voice from the microphone 5, compares the received command voice with the registered voice, and when they match, automatically dials the other party who gave the command. In addition, if the command voice attached and the registered voice do not match, the receiver searches for all the people whose voices are similar (possible people) from among the registered voices, and selects speaker 7 in the search order. make an announcement from

The microphone 5 is placed, for example, at a predetermined position in front of the driver on the instrument panel 11 shown in FIG. 2, so that it can effectively input the driver's voice. As shown in FIG. 2, the speaker 7 is built into the headrest 16 of the driver's seat 15, and is placed near the ears of a seated driver. Thereby, the driver can listen to the audio (announcement) output from the speaker 7 well.

The confirmation switch 6 is a switch for confirming when the voice output from the speaker 7 matches the name of the commanded party, for example, and is placed in a place that is easy for the driver to operate, such as the steering wheel 12 shown in FIG. It is located.

The indicator 9 is for displaying that the other party is being searched. Further, the control device 3 lowers the volume of the audio number 10 when making a phone call to make it easier to communicate.

The operation will be explained below with reference to the flowchart shown in FIG.

When registering the other party's name in the voice recognition computer built into the control device 3, press the registration/command switch 4.
on the registration side, and speak the other party's name into the microphone 5. The voice recognition computer receives voice information input from the microphone 5 and registers (memorizes) it (step 1). In this way, the voice recognition computer requires the name of the other party, e.g.
Register rf3J, rEJ, rFJ, and rlJ in sequence.

When the driver makes a phone call while driving, after setting the registration/command switch 4 to the command side, speak the other party's name into the microphone 5, such as 'Mr. FJ1.
command (step 2). The control device 3 searches for Mr. “F” from among the registered voices based on the input voice information (step 3), and the speaker 7 searches for “Mr.
Announce Mr. F. The speaker 7 is built into the headrest 16 of the driver's seat 15 and is placed near the driver's ear. Therefore, the driver can listen to the speaker 7 even while driving.
announcements can be heard clearly. The driver listens to this announcement and confirms whether it matches Mr. rFJ (step 4), and if the answer is affirmative (YES), presses the confirmation switch 6. When the confirmation switch 6 is pressed, the control device 3 causes the telephone body 2 to automatically dial the other party, that is, Mr. "F" (step 5), and then returns to step 2. The driver then says, ``Communicate with Mr. Fj using microphone 5 and speaker 7.

If the answer to step 4 is negative (NO), the control device 3 lights up the indicator 9 (step 6), and
Candidates “B”, “Ej,” “I” who are similar to the commanded voice among the voices registered in addition to “F”
'' and make announcements sequentially from the speaker 7 (step 7), and determine whether or not the confirmation switch 6 is pressed (
Step 8). The driver waits until the speaker 7 announces the three candidates "B", "E", rFj, and "■", that is, "Mr. Fj".

The driver presses the confirmation switch 6 when the three candidates "Mr. FJ" are announced from among the candidates sequentially announced from the speaker 7 near his ear. When the confirmation switch 6 is pressed, the control device 3 The discriminant answer of 8 is affirmative (YE
In the case of S), the process returns to step 2 after automatically dialing the other party "F" (step 9).

If the answer to step 8 is negative (No), for example, if the driver missed Mr. rFJ's announcement and did not press the confirmation switch 6, the control device 3 determines whether there are any candidates (-). If the answer is negative (NO), the process returns to step 7 and the candidate is announced (step 7). That is, the control device 3 sequentially announces "rB", "E", "F", and "I", and then announces "■" until the answer to step 10 becomes affirmative (YES). In other words, when there are no more registered candidates,
"Please give me a command" to remind the driver and return to step 2.

Therefore, at this time, the driver is already "Mr. F".
command.

(Effects of the Invention) As explained above, according to the present invention, in a voice command type car phone that automatically dials when a command voice is input and the voice matches the registered voice, the command voice and the registered voice can be used. If they do not match, multiple candidates who are similar from among the registered voices are announced using the speaker built into the headrest of the driver's seat, and when the three candidates are found, the confirmation switch is used to confirm the candidates. Equipped with a control means for automatic dialing, the announcement is made in the driver's ears, making it easier to understand, and since automatic dialing can be performed using only voice means, it is easier to make calls while driving, and commands When the voice and the registered voice match, the other party can be selected by simply operating a confirmation switch, and there are four excellent effects such as ease of making hands-free phone calls while driving.
