Abstract

PURPOSE:To automatically classify and retrieve the contents of a voice mail by previously specifying the key word and contents of a voice message by vocalization or character information. CONSTITUTION:A voice is inputted through a microphone 101 and amplified and converted from analog to digital to constitute a standard pattern for retrieval, which is sent to a control part 104 and further sent to a speech recognition part 106. Then, the voice mail to be retrieved is read out of a voice mail storage part 107 to the control part 104 and sent to the speech recognition part 106. The speech recognition part 106 detects the speech standard pattern of the key word to be retrieved from the voice mail to be retrieved by word spotting. Further, the control part 104 judges whether or not the voice mail to be retrieved contains the key word from the result of the speech recognition part 108, and a speech output part 109 performs D/A conversion and outputs the voice mail from a speaker 110. Further, the voice mail is classified by the retrieval result and stored again in the storage part 107.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a voice message retrieval device having a function of classifying and retrieving stored voice messages, which is used in a voice mail system or the like for storing and transmitting voice messages by patternizing voice information as it is and digitizing it. Is.

[0002]

2. Description of the Related Art A voice mail is very useful because it has a large amount of information that effectively conveys not only the meaning and meaning of the transmitted speech but also the emotion and intention of the sender.

However, in the conventional voice mail system for electronically storing and transmitting a voice message, since the information remains the voice information, it is difficult to perform a search by characters or the like, and the search is very difficult. Therefore, in order to obtain the required information, it was necessary to listen to all the stored voice messages and select the desired voice message. Moreover, even after selecting an individual voice message, it was not possible to know whether or not the necessary information was included until the end of the message was heard. As described above, in the conventional device, it takes time and difficulty to acquire information.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and automatically specifies a keyword and content for a voice message by voice or character information in advance. It is an object of the present invention to provide a voice mail search device capable of classifying and searching the contents of voice mail.

[0005]

In order to achieve this object, a voice mail retrieval apparatus of the present invention is a voice mail system for converting a voice message into pattern voice information, storing the voice message, and transmitting the voice information as needed. A voice mail search device for searching the voice information, comprising: storage means for storing the voice information; input means for inputting a keyword of the voice information; and voice information search based on the keyword, and the search. A control unit that controls to classify voice information based on the result and store the voice information in the storage unit, and automatically retrieves and classifies the voice information based on the keyword. is doing.

[0006]

The input means inputs a keyword or content specifying information represented by voice information or character information. Based on the information, the control means creates a standard pattern such as a phoneme or a word, recognizes this from a voice mail, spots it, searches it, and classifies it.

[0007]

1 is a block diagram of a voice mail search device according to the present invention.

When a keyword used for a search is input in characters, characters are input from a character input device 103 such as a keyboard, and the control unit 101 stores a standard pattern of voice corresponding to this character as a phoneme and a word acoustic pattern. It is composed of the acoustic pattern of the part 105. Here, the standard pattern may be either the voice feature series itself or any modeled one.

When the keyword used for the search is input by voice, the voice is input from the microphone 101, amplified by 102, A / D converted to form a standard pattern for search, and sent to the control unit 101.

Next, the search voice standard pattern sent by the control unit 101 is sent to the voice recognition unit 106. Next, the voice mail to be searched is read from the voice mail storage unit 107 to the control unit 101 and sent to the voice recognition unit 106. Here, the voice mail stored in the voice mail storage unit 107 is read by the telephone line or the private line 108.

The voice recognition unit 106 detects a voice standard pattern of a keyword to be searched from a voice mail to be searched by word spotting.

The word spotting method is based on a dynamic programming method such as continuous DP between speech feature sequences,
Any of word spotting based on a statistical method such as a hidden Markov model may be used.

The control unit 104 determines whether or not a keyword is included in the voice mail to be searched based on the result of the voice recognition unit 108, and the voice output unit 109 outputs D
It is output by the speaker 110 that performs A / A conversion. Also,
The search results are classified and stored again in the voice mail storage unit 107.

[0014]

According to the conventional apparatus, the retrieval and classification have to be performed manually, but according to the present invention, since the retrieval of the voice mail is automatically processed based on the keyword, desired information can be quickly obtained. It will be possible to obtain it. Further, since the information is classified and stored based on the search result, the information can be organized according to the purpose of use of the user.
