ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a communication system provided with a user terminal connected through a communication network and a transmission server that sends prescribed information to a wireless terminal such as a pager that expresses by means of characters or voice information from a user terminal.
2. Description of the Related Art
In recent years, portable wireless terminals for individual use such as portable telephones, personal handy phone systems (PHS) and pagers have become common. With such portable wireless terminals, exchange of speech or data can be performed using wireless circuits.
Furthermore, as computer communication networks typified by the Internet have become widespread, data communication between computers has become easy.
In this connection, a technique has been proposed whereby, with a portable telephone or PHS (sending-side wireless terminal), voice data or character data is sent to the server on the provider side through the Internet and this server sends prescribed information based on the voice data and/or character data that it receives to the receiving-side wireless terminal (for example, a pager). In this technique, it is desirable that the sending terminal device should be capable of transferring prescribed information to the receiving wireless terminal.
For example, in Early Japanese Patent Publication No. H.3-289854, an electronic mail system is disclosed in which a voice input mark is inserted in received mail and the received mail is read out loud at the receiving end; when the voice input mark is detected, reading out loud is interrupted, and reply information can be received by putting the voice input mechanism into operable condition. With this system, received electronic mail can be listened to by ear and a reply thereto can be input by voice, so the effort required in replying can be reduced. Also, an electronic mail system is disclosed in which, since input can be effected by voice, replies can be sent from telephones and replies from the destination are possible.
In this system, the correspondence between the message information of the electronic mail and the voice information is one-to-one and the message information is uttered by being converted for example into standard speech. Of course, with this method also, it is information that is transmitted. However, if it is sought to transmit information more precisely, the difference between character message information and voice information must be considered. Specifically, although the intention to be transmitted is expressed by the characters contained in the message information, the intention that is expressed is subtly changed by selection of voice, selection of feeling of urgency, and selection of emotional expression of mood, in addition to the characters contained in the voice of the voice information that is uttered. For example, even the same expression, which, if pronounced clearly might be rather strong, if said rather more softly, becomes a more gentle expression. Consequently, in order to accurately express the intention, it is desirable to be able to represent emotional expressions such as tone colour, feeling of urgency and mood.
Also, when information is transferred from a sending wireless terminal through the server at the provider end to another terminal, in order to compress the amount of data, it is desirable that, rather than simply sending the voice or characters without modification, it should be possible to convert the voice or characters, depending on the conditions and the application. And for example, many varieties of humorous expression are possible by using for the language, instead of standard speech, Tohoku dialect or Kansai dialect etc. or languages such as English, French, German, Russian or Chinese.
Also, it is desirable that the user should be able to receive desired information independently of the type etc. of the receiving terminal device.
Furthermore, since the performance and efficiency of processing change depending on whether the processing is performed at the terminal or the server at the provider end, a suitable apportionment of roles is necessary.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a communication system and wireless communication terminal whereby intentions can be transmitted more accurately. A further object of the present invention is to provide a communication system and wireless communication terminal whereby desired information can be transferred independent of the type etc. of the receiving terminal.
A communication system according to the present invention comprises at least one wireless communication terminal device and provider equipment capable of information transmission between itself and this wireless communication terminal device wherein the wireless communication terminal device includes a transmission section that sends message information and selection information for selecting the form of output of the message information and the provider equipment includes a processing section that outputs the message information in an output form in accordance with the selection information. Intentions can be more accurately transmitted by means of the selection information.
A wireless communication terminal device according to the present invention comprises a voice identification section that identifies an input voice signal and converts it to message information and a transmission section which receives the message information and selection information for selecting the output form of the message information, and sends these.
According to the present invention, a voice signal is recognised by a wireless communication terminal and its output form is converted as desired and the converted voice signal is transferred through the provider equipment to another, destination wireless communication terminal device. In this way, sound quality of the input voice can be guaranteed since the voice is recognised by the wireless communication terminal device at the sending end; it is therefore possible to improve the voice recognition rate. Also, since conversion of the output form is performed by the wireless communication terminal device, this conversion does not require authentication by the provider equipment.
Furthermore, since conversion of the output form of the voice is performed at the wireless communication terminal device at the sending end, communication time with the provider equipment can be cut and, as a result, service charges can be reduced.
Even if, with this system, the output form conversion is effected by the provider equipment, voice recognition is performed by the wireless communication terminal device constituting the sending end. As a result, the voice recognition rate is not impaired.
A wireless communication terminal according to the present invention comprises: a voice identification section that identifies an input voice signal and converts it to message information; a table whereby a correspondence is set up between characters and numerals, and/or set phrases and a code matching the sending party; a code conversion section that refers to this table so as to be able to reproduce at the sending end the characters, numerals and/or set phrases constituting the character series of the message information and converts these to a prescribed code; and a transmission section that receives the converted code and the selection information that selects the output form of the message information and that sends these.
Further, objects of the present invention are achieved by a wireless communication terminal device comprising the above construction.
