2. Description of the Related Art As the use of a radio selective call receiver becomes widespread, its service contents are also required to have higher functions and diversification. Examples of the service contents currently being provided include calling, transmission of numeric and character information, and the like. Transmission of shorter audio information is also going to be performed. Japanese Patent Laid-Open Publication No. Hei 3-60227 discloses that A / D conversion is performed on audio data input via a telephone network, and the digital data is transmitted wirelessly. A technique is described in which digital data received by a paging receiver is converted back to analog data by a D / A converter and output as audio from a speaker.
[0003]
In a radio selective call receiver capable of storing voice information in addition to numeric and character information, the reproduction of numeric information and voice information is usually performed by the operation of a radio selective call receiver carrier. Then, it is displayed on a display device or converted into an audio signal. In this case, when the mixed information of the numeric message and the voice message or the single information of either is transmitted, the called party does not know the whole of the stored information, reads the numeric message on the display, and reads the voice information on the speaker or the like. You need to do everything you hear. Although the numeric message is obvious at a glance, the voice message does not know the existence of the information unless it is reproduced. In addition, there is also a problem that the end of the audio information is not known at the time of the audio reproduction, so that there is a feeling of irritation as to how long the audio information will continue. Furthermore, the radio selective calling receiver is required to have low power consumption in order to reduce the frequency of battery replacement.
[0004] It is an object of the present invention to provide a radio selective call receiver that allows a called party to quickly ascertain the type of stored information received. It is another object of the present invention to provide a radio selective call receiver which allows a called party to quickly grasp the amount of received voice information. Still another object of the present invention is to provide a radio selective call receiver which can prevent useless reproduction operation and consumes less power.
[0005]
In order to achieve the above object, the present invention provides a radio selective call receiver having at least a means for receiving and storing voice information, a means for checking the information amount of voice information, Display means for displaying the amount of audio information. The means for checking the information amount of the voice information includes a case where only the presence or absence of the voice is obtained and a case where the information amount of the voice information stored in the storage means is obtained. Although the display means is not particularly limited, the presence / absence and the amount of the audio information are displayed in a display form that can be easily identified by symbols, colors, and graphs.
Further, when other information such as character information, numerical information, and symbol information is added to the transmission information in addition to the voice information, a means for identifying the type of the reception information is added to the display means. The type of the received information is displayed on the display means. The display form is arbitrary, but it is preferable that the information of the type of the received information is displayed in characters, colors or symbols so that it can be easily identified instantly.
Further, the reproducing section of the receiving apparatus has driving means for the user to select and reproduce based on the information amount of the audio information and the display result of the type of the received information, that is, a selection switch, a reproduction switch. Is provided. The means for examining the information amount of the audio information, the means for identifying the type of the received information, and the means for driving the display means may be provided with a dedicated device, but a microprocessor which also serves as a demodulation operation of the receiver (Microcomputer) function.
[0008]
When the character or symbol indicating that the voice information is stored in the storage means is displayed on the display, the called party who is the receiver of the receiver can recognize the voice information contained in the incoming message. Can be discriminated, so that useless reproduction operation for listening to audio information can be prevented. Also, since the called party can grasp the information amount of the stored voice information, the irritation of not knowing the end of the voice information can be eliminated, and the time to move to the next action can be predicted, thereby wasting time. . In addition, since the reproducing circuit does not operate even if the reproducing operation is performed by mistake when there is no audio information, unnecessary current consumption of the circuit can be suppressed, the built-in battery can be saved, and the actual battery life can be extended. it can.
