In the drawings, the same components as those of the conventional radio broadcast receiving device are denoted by the same reference numerals.

In FIG. 1, 1 is an antenna, 2 is an amplifier, 3 is a radio signal demodulation unit, 4 is an error correction unit, 5 is a signal separation unit, 6 is an audio output unit, 7 is a display processing unit, and 8 is a display device. , 9 is a control device, 10 is a storage device, and 11 is operation instruction means (buttons and the like), which have the same configuration and operate in the same manner as in the above-described conventional example, and thus description thereof will be omitted.

The configuration of the first embodiment is characterized in that a voice recognition device 12, a voice input unit 13, and a voice synthesis device 15 are connected to the control device 9 in addition to the connection of the storage device 10 and the operation instruction means 11. It is in. The voice input unit 1
The A / D converter 14 is inserted in the signal path 3.

The function of automatic selection of the receiving frequency in the radio broadcast receiving apparatus having the above configuration will be described with reference to the flowchart of FIG. 2 and the tables of FIGS.

In step 1-1 shown in FIG. 2, the radio broadcast receiving apparatus decodes the radio signal received from the antenna 1 through a process such as demodulation and error correction. (Step 1-2). In this state, the wireless broadcast receiving apparatus waits for a voice or an input from the operation instruction unit 11 as an operation instruction of the user (step 1-3).

The user's instruction may be issued by voice and instructing means such as a switch, but here, only the case where the voice instruction is given will be considered. When the user utters a word indicating the field of the broadcast to be received toward the voice input unit 13,
The voice data is quantized by the A / D converter 14 and subjected to recognition processing by the voice recognition device 12 based on the data (step 1-4), and the recognition result is transmitted to the control device 9 (step 1-5). ). The control device 9 compares the word of the recognition result with the heading word of the field-specific word table as shown in FIG. 3 described below according to the program stored in the storage device 10 and searches for a matching word (step 1). -6).

Next, in step 1-7, the control unit 9 searches for a frequency that can be received at a certain level or higher while adjusting the frequency to a preset frequency or scanning the frequencies sequentially. Receive one broadcast. Next, during the reception, the voice data of the broadcast is input to the voice recognition device 12, and a continuous word voice recognition process is performed. The process of step 1-7 is continued for a fixed time, and the recognized words of the voice being broadcast are accumulated in the storage device 10 (step 1-8). After a lapse of a predetermined time (step 1-9), the recognition process is stopped (step 1-10), and the accumulated recognition words (see FIG. 4).
Then, the word group in the word table previously searched in step 1-6 is compared with the word group stored in step 1-8, and the number of common words is counted (step 1-).
11).

Next, at step 1-12, it is determined whether or not the counted number exceeds a preset threshold value, and if so, the process at step 1-13 is performed. If the frequency does not exceed the threshold value, it is determined in step 1-14 whether there is a frequency that can be further tuned. If so, the flow returns to step 1-7 to repeat the subsequent processing. If not, proceed to step 1-15. In step 1-13, it is determined that the currently received broadcast is in the field desired by the user, and the frequency of the broadcast is stored.

Thereafter, the process proceeds to step 1-14. In step 1-15, it is determined whether or not the frequency stored in step 1-13 is present.
If the following processing is not performed, the message to the user is output as voice by the voice synthesizer 15 in step 1-18.

For example, if the user desires baseball broadcasting, the message will be something like "There is no baseball broadcasting". Then, step 1-1
In step 9, the voice synthesizer 15 is used to output voice guidance such as "Do you have any other desired broadcasts?", And wait for a response from the user before processing. If the user replies affirmatively such as "Yes", the processing from step 1-3 is performed, and if the user replies negatively such as "No", all the processing is performed in step 1-20. finish.

In step 1-16, the broadcast of the stored frequency is received and output to an output device or a display device. Next, in step 1-17, the voice synthesizing device 15 is used to give a guidance message such as "Is this broadcast acceptable?" And wait for the user to make a decision. If there is an affirmative reply such as "Yes" here, the process ends in step 1-20. If the answer is negative, such as "No", the process returns to step 1-15 to receive the stored broadcast of the next frequency and repeat the same number of times as the stored frequency.

The operation described here as an example can be performed manually from the operation instructing means 11 as a matter of course.

Although the genre of the broadcast is estimated using characteristic words used in the broadcast, the genre of the music is estimated based on the same idea, for example, for the same music broadcast. It is possible to In other words, melodies and rhythms that represent the characteristics of music for each genre such as "rock" and "enka" are stored in the word table in the above example, and matching is performed based on information on music being broadcast. That is to look for.
