JPH02248145A - Voice dialer - Google Patents

Abstract

PURPOSE:To improve the recognition ratio and to attain automatic dialing in voice by applying automatic grouping according to an extension and an external line at registration, using only the grouped number of the extension at the extension call as the recognition object and using only the grouped number of the external line at the external line call as the recognition object. CONSTITUTION:Whether a caller designates whether a call is made to an external line or an extension at the dialing and the uttered voice is collated with a standard pattern corresponding to the dial number in the designated group to obtain the result of collation. Even at the transfer, the similar processing at the dialing is implemented and after the call is in holding, the designation of an external line or an extension is applied to make uttering. Thus, a voice dialer consists of a handset 1 incorporating a microphone section 2, a characteristic extraction section 3, a standard pattern storage section 4, a pattern collation section 5, a key input section 6, an external line/extension number identification section 7, a nominal number storage section 8, a result output section 9, a number collation section 10 and a dial circuit section 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice dialing device, and more particularly to a voice dialing device having a transfer function for use within a premises.

A voice dialing device that automatically outputs a dialing signal by voice input when making a call to make a call, instead of dialing manually, has already been proposed in, for example, Japanese Patent Laid-Open No. 6'L-144157. I'm nine.

Furthermore, dialed numbers are automatically grouped by area code, and by specifying the area code before speaking, recognition is limited to only names in the group corresponding to that area code, improving recognition rate. For example,
Unexamined Japanese Patent Publication 1986. It has been proposed in Publication No. +306748 and the like.

However, in the voice dialing device described in Japanese Patent Application Laid-Open No. 63-306748, the caller had to manually input the pJffi of the call before speaking. Furthermore, no effort has been made to distinguish between internal and external calls in local telephones.

The present invention was made in view of the above-mentioned circumstances, and
Grouping according to extensions and outside lines is automatically performed at the time of registration, and when calling an extension 11, y, only numbers grouped into extensions are recognized, and when making an outside call, only numbers grouped into outside lines are recognized. By targeting this, we aim to improve the recognition rate.

Moreover, an automatic dialing function by voice is provided by similar processing when an extension line transfer or a Tato line transfer is performed.

In order to achieve the above-mentioned object, the present invention includes a feature extraction section that extracts the feature amount of the voice for a name input by voice, and a feature amount extracted by the feature extraction section that is standardized. A standard pattern storage unit that stores the pattern as a pattern; a number storage unit that stores the dial number corresponding to the name input by voice; and the feature amount extracted by the feature extraction unit during voice input and the four votes stored in advance. A pattern matching section that recognizes which '4M$ pattern the input voice corresponds to by performing pattern matching with the feature amount in the quasi-pattern storage section, and a dial number of the name corresponding to the recognition result by the pattern matching section. in a voice dialing device co-produced with a calling circuit that reads the number from the number storage unit and outputs a dialing signal, the voice dialing device is characterized in that the dialed number at the time of registration is automatically grouped according to the extension or outside number. Furthermore, when recognizing a call or transfer, if the voice dialing device before speaking is set to make an outside line, only the standard pattern corresponding to the dial number grouped into the outside line will be recognized. To limit the target, or when recognizing the above call or transfer, if the voice dialing device before speaking is set to call an extension, use a standard pattern corresponding to the dial number grouped into the extension. If the voice dialing device before speaking is not set to a specific call target when recognizing a call or transfer, the recognition target is a standard pattern that corresponds to all groups. It is characterized by the following. Hereinafter, the present invention will be explained based on examples.

FIG. 1 is a configuration IM+ for explaining an embodiment of a voice dialing device according to the present invention, and FIG. 2 is a flowchart 1 to ILF registration, in which 1 is a handset, 2 is a microphone unit, 3 is a feature extraction unit, 4 is a standard pattern storage unit, 5 is a pattern matching unit, 6 is a key input unit, 7 is an outside line/extension number identification unit, 8 is a name number storage unit, 9 is a result output unit, 10 is a number Verification section, 11 is the transmitting circuit section, registration +1
:5: indicates that the telephone number entered from the key personnel department 6 is an outside line,
It is distinguished in the extension number identification section 7, and the name number storage section 8
is memorized. For example, the first digit of an external line number is O.
, and it is sufficient to assume that the extension starts with a number other than that (Figure 3 shows the state of the registered number storage section).

Further, the 4fF quasi-pattern inputted after this is stored in the standard pattern storage section with data indicating the extension line and outside line added thereto.

When making a call, the caller first specifies whether to make a call to an outside line or an extension. In this case, if the dialing device is already set to the desired line, there is no need to specify it. The designation method varies depending on the dialing device, such as using a dedicated button for one button, or adding a number to the beginning of the dial, but the details are omitted here.

After this, the spoken voice will only be matched against standard patterns corresponding to dialed numbers within the specified group.
Obtain recognition results.

Also, when transferring the call, it is the same as when making a call; after putting the call on hold, specify an outside line or extension, make a utterance, recognize only the dialed numbers within that group, and obtain the result.

Furthermore, when making a call or transferring a call, unless an extension or an outside line is specified before making a call, all standard patterns corresponding to dial numbers in both groups are to be recognized.

As is clear from the above explanation, according to the present invention, it is possible to automatically distinguish between internal and external lines, and during recognition, the probe (Q) corresponding to the number in the group is automatically distinguished. Since it is possible to narrow down the objects of awareness only to patterns, it is possible to improve the recognition rate.

Claims (1)

[Claims] 1. A feature extraction unit that extracts the feature quantity of the voice input with respect to the name input by voice, a standard pattern storage unit that stores the feature quantity extracted by the feature extraction unit as a standard pattern, and a name input by voice. By performing pattern matching between the number storage section that stores the dial number corresponding to the name being entered, and the feature amount extracted by the feature extraction section during voice input and the feature amount stored in the standard pattern storage section that is stored in advance. A pattern matching unit that recognizes which standard pattern the input voice corresponds to, and a transmission circuit that reads out the dial number of the name corresponding to the recognition result by the pattern matching unit from the number storage unit and outputs a dial signal. What is claimed is: 1. A voice dialing device comprising a voice dialing device, which automatically groups dialed numbers according to extensions and outside lines at the time of registration.
