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 for the first time, announcing a relevant party confirmed at the first time for 2nd and succeeding calla and 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. 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 when the name is coincident, the driver depresses the confirmation switch 6 to apply automatic dialing to the telephone number of the opposite party. The relevant party retried and confirmed by the switch 6 is stored for the first time, and the relevant party is announced at first in the 2nd and succeeding announcements while the arrangement of the announcements is replaced. When the name is coincident, the switch 6 is depressed and the opposite telephone number is automatically dialed.

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 repeat'' is displayed and the driver is requested to speak the command again.

By the way, at present, the recognition rate of command voices is low8.
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. When there is a suitable person, operate the confirmation switch to automatically dial the number, and when there are multiple candidates with the first command and the second and subsequent announcements are made,
The purpose of the present invention is to provide a voice command type car telephone that gives priority to this person and makes an announcement first from next time onwards.

(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 does not match the registered voice, a speaker built into the headrest of the driver's seat will announce multiple candidates from among the registered voices to the reception search layer for the first time. When the confirmation switch is announced, the system automatically dials the confirmation switch, and when the confirmation switch is pressed for the second and subsequent announcements, this is memorized, and when the command of the person in question is accepted for the second time. After the search, the announcement order is changed so that the corresponding person is announced first, and from the second time onward, the corresponding person is announced first.

(Operation) When the command voice and the registered voice do not match, the control means selects a plurality of similar candidates from among the registered voices from a speaker built into the headrest of the driver's seat. -The second time will be announced to the search layer. If the confirmation switch is operated when the appropriate person is announced, the call will be made automatically. At this time, if the confirmation switch is pressed for the second or subsequent announcements, this will be memorized, and next, when the command of the relevant person is accepted for the second time, the order of the announcements will be changed after the search, and the From the second time onwards, this person will be given priority and announced first. This allows you to automatically dial the other party with the minimum necessary operations even if the voice is confusing.

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

In FIG. 1, a voice command type car phone 1 includes:
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 IO, 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 includes a computer for voice recognition,
When the registration/command switch 4 is set to the registration side, the audio input from the microphone 5 is accepted and registered in the memory, and when the registration/command switch 4 is set to the command side, the command audio from the microphone 5 is accepted and the reception is performed. The command voice is compared with the registered voice, and if they match, the telephone 2 is caused to automatically dial. In addition, when the received command voice and the registered voice do not match, all the people whose voices are similar (possible people) are searched from among the registered voices and the reception search layer is sent from the speaker 7. make an announcement.

Furthermore, the control device 3 stores this when there are multiple candidates for the other party and the corresponding person's announcement order becomes second or later due to the -th command, and from the second time onwards, the control device 3 stores this, and from the second time onwards, The announcement order is rearranged so that the announcement order is set first, and from now on, when this corresponding person is given a command, the announcement is given first over others.

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 rBJ, "E", rFJ, and "I" in the order of reception.

If the driver wants to make a phone call while driving, after setting the registration/command switch 4 to the command side (step 2), speak the other party's name into the microphone 5, such as ``Mr. ■''. The command is recognized (step 3).The control device 3 recognizes the input voice and searches for "Mr. IJ" from among the registered voices.At this time, the control device 3 recognizes the input voice and searches for "IJ. It is determined whether or not (step 4), and if the answer is affirmative (YES), the number of announcements n is set to l (n=1) (step 5).

At this time, if there are multiple candidates rBJ, rE", and "Fj" whose voices are similar to "I" in addition to "I", first in the search order, "Ms. Bj will be announced from speaker 7 (step 6)". The speaker 7 is built into the headrest 16 of the driver's seat 15 and placed near the driver's ear, so the driver can clearly hear announcements while driving.

The driver listens to the announcement made from the speaker 7 and presses the confirmation switch 6 when the announcement is made.The control device 3 determines whether or not the confirmation switch 6 has been pressed (step 7). .-The first time is "B"
Mr. J has been announced, therefore, the confirmation switch 6 is not pressed, the decision answer in step 7 is negative (NO), and the control device 3 determines whether the number of announcements n exceeds the upper limit n0 (n≧no). Determine (step 8). At this time, it is still the first announcement, and the decision answer in step 8 is negative (No), and the control device 3 advances the number of announcements n by 1 (step 9), sets nx+=n (step 10), and proceeds to step 6. I went back and announced Mr. E second after Mr. B.

Similarly, when the driver presses the confirmation switch 6 when Mr. "F" is announced third and Mr. NJ is announced fourth, the answer to step 7 becomes affirmative (YES) and the process proceeds to step 12.

Also, if you miss Mr. "■"'s announcement and the number of announcements n exceeds the upper limit n, the answer to step 8 will be affirmative (YES) and the system will announce, "Please command again." In step 11), the command is requested from the driver again, and the process returns to step 2.

In step 12, it is determined whether the announcement order of Mr. "!" is the second or later (n≧2). In this case, it is the -th search, and "Mr. IJ's announcement is the fourth, the number of announcements n is 4 (≧2),
The determination answer in step 12 is affirmative (YES). The control device 3 sets and memorizes the flag EXI as l (step 13) in order to change the order of Mr. IJ's announcement to the first, and then automatically dials Mr. r[+ (step 1
4) Do. The driver then communicates with Mr. "■" using the microphone 5 and speaker 7.

Next, in order to call Mr. “■” again for the second time, “I
When the command is recognized (step 3) by saying “Mr. ”,
The search is performed in the order of Mr. rlJ, and it is determined whether or not the command is the first time (step 4). At this time, the command is used for the second time, and the answer to step 4 is negative (No).
becomes.

The control device 3 determines in step 15 whether or not the order of announcements needs to be changed, that is, whether Ext=l. At this time, ExI=1 has already been set, and the determination answer in step 15 is affirmative (YES). Therefore, the control device 3 rearranges the order of the announcements and displays "■".
, "BJ," EJ, rFJ, and remember "■"'s announcement order flx+ as the first step 16).
Announce rlJ first (step 6)
)do.

The driver presses the confirmation switch 6 when Mr. "I" is first announced from the speaker 7. In the control device 3, the confirmation switch 6 is pressed and the answer to step 7 is affirmative (YES).
), it is determined in step 12 whether or not the announcement order of Mr. "■" is the second or later (n≧2). At this time, since Mr. "■" has been announced first, the determination answer in step 12 is negative (No). Therefore, the control device 3 sets Ext to 0 (step 17
), then automatically dial “I” (Step 14)
and return to step 2.

Then, for the third time, "■" to call Mr.
When the command is recognized (step 3), the control device 3 recognizes the candidates "B", "E", "F", and "■" in the same way as the first time based on the input voice information. A search is made for Mr. rlJ from among them, and it is determined whether or not this is the first time the command has been issued (step 4). At this time, the command is issued for the third time, and the answer to step 4 is negative (No).

The control device 3 determines in step 15 whether or not the order of announcements needs to be changed, that is, whether Ex+=l. However, in this case, Ex+=O, and the order of announcements is "I", "B", rE", "F".
”, there is no need to change the order of announcements, and therefore the answer to step 15 is negative (NO). Therefore, the control device 3 selects "B", "E",
After searching for "F" and "I", "Announce Mr. IJ first (Step 6).

The driver presses the confirmation switch 6 when "I" is announced first. The control device 3 includes a confirmation switch 6
When is pressed and the answer to step 7 is affirmative (YES),
rIJ's announcement order is second or later (n≧2)
It is determined whether or not (step 12). ``Because Mr. IJ was announced first, the discriminant answer in step 12 is negative (No), and with flag E!1 set to 0 (step 17), Mr. ``I''- is automatically dialed (
Step 14) and return to Step 2. As a result, even confusing voices can be automatically dialed with the minimum necessary operations.

Note that if the first registered person "B" is commanded, there is no need to change the order of announcements from the second time onwards, and the announcements will be made in the searched order. That is, at the -th command, the answer to step 12 is negative (No), flag EXB is set to O in step 17, and automatic dialing is performed (step 14). Next, when the second command is issued to call Mr. BJ, the answer to step 15 is negative (No), and step 5
The process proceeds to Step 12, which results in a negative result (No), and the process proceeds to Step 17, where Mr. rBJ is automatically dialed (Step 14).

When the vehicle is stopped and the ignition key is turned off, the control device 3 resets the order of announcements with "I" at the top and changes to the first reception mode (at the time of registration) rB, +, "E". ", rF", return to rIJ. this is,
This is because the frequency of announcements differs depending on the driver, and the order of announcements can be rearranged accordingly.

(Effects of the Invention) As explained above, according to the present invention, in a voice command type car telephone that manually inputs a command voice and automatically dials when it matches a registered voice, If the voice does not match, the speaker built into the headrest of the driver's seat will announce multiple candidates that are similar from among the registered voices in the order of reception search, and when the corresponding person is announced, the confirmation switch will confirm. In addition to automatically dialing the number after the second announcement, this will be memorized when the confirmation switch is pressed for the second and subsequent announcements, and when the command of the corresponding person is accepted for the second time, the announcement order will be changed after the search and the corresponding person will be dialed automatically. By providing a control means to make the announcement to the driver first, and to make the announcement to the driver first from the second time onward, the announcement is made in the driver's ear, making it easier to understand, and also by voice means alone. Automatic dialing makes it easier to make calls while driving, and when the command voice matches the registered voice, you can select the other party by simply operating the confirmation switch. By giving priority to the first caller and making the announcement first, even if the voice is confusing, it can be automatically dialed with the minimum necessary operations, making it easier to make hands-free calls while driving. effective.
