., D115 of the multipliers 201, 202, 203,..., 215 are set by the weight coefficient setting unit 52.
This makes it possible to easily correct the received signal in the audible frequency band.
FIG. 6 is a diagram for explaining the weight coefficient holding unit 16C of FIG. As shown in the figure, the weighting factor holding unit 16C stores weighting factors Ai (i = 101 to 115) of the language used by the communication partner for each output of the BPFs 101, 102, 103,. The coefficient Bi (i = 101 to 115) and the weight coefficient Ci (i = 101 to 115) of the feature (loudness) are held.
[0028]
The weighting coefficient Ai of the language used is Ai = 1 (i = 101 to 115) with the case of "Japanese" as a standard.
The gender weighting coefficient Bi is Bi = 1 (i = 101 to 115) with the case of “female” as a standard.
The weight coefficient Ci of the feature (loudness) is Bi = 1 (i = 101 to 115) with the case of “normal” as a standard.
[0029]
When the language used is “English”, as an example, the weighting factors for the BPFs 113 to 115 (bulks 15 to 17) are reduced to 0.5 times, and high-frequency components are attenuated. This is for removing the high frequency components of 2.5 kHz or more contained in the English conversation for the Japanese user, facilitating the listening, and improving the clarity during the call.
[0030]
Next, when the gender is “male”, as an example, the weighting factors for the BPFs 111 to 115 (bulks 13 to 17) are doubled to increase the components in the high frequency range. This is because it is possible to improve clarity by setting a weighting factor while paying attention to a frequency at which a voice formant based on gender exists. That is, for example, in the case of a male utterance, the voice formant generally has a lower tone than that of a female, so that it often has a muffled sound with lower clarity than a female.
[0031]
Next, when the feature of the utterance (loudness of the utterance) is “large”, for example, it is reduced to 0.5 times (Bi = 0.5; i = 101 to 115).
When the feature of the utterance (the magnitude of the utterance) is “small”, for example, it is increased to twice (Bi = 2; i = 101 to 115).
In this way, by adjusting the level of the entire frequency band in accordance with the characteristics of the individual utterance (loudness of the utterance) during the call, the received voice level during the call can be adjusted to a certain width. This is to eliminate the necessity of performing operations such as volume adjustment of the camera.
[0032]

The weight coefficient is selected from the weight coefficient holding unit 16C.
[0033]
The weighting factor calculation unit 52B reads out the weighting factor from the weighting factor holding unit 16C of the memory 16 for the reception parameter selected by the weighting factor selection unit 52A, and converts the reception signal weighting factors D101, D102, D103,. The calculation is performed as follows.
Di = Ai × Bi × Ci (i = 101 to 115)
[0034]
The weighting factor setting unit 52 sets the received signal weighting factors D101, D102, D103,..., D115 calculated by the weighting factor calculation unit 52B in the multipliers 201, 202, 203,. I do.

Although the above description has been made with respect to a portable telephone radio, the present invention can be used as it is for a communication device such as a PHS (Personal Handy Phone System), a digital home telephone, or the like.
[0047]
In addition, by using the correction means of another language for an audio / video device such as a television and a stereo, it is possible to correct a broadcast of another language and to improve the clarity of conversation.
[0048]
【The invention's effect】
As described above, according to the present invention, in accordance with the name and telephone number of the telephone directory, the language, gender, and utterance characteristics of the other party are stored as reception parameters, and are stored in the parameter storage unit. Holds weighting factors for correcting the level of the divided frequency band for each language, gender, and utterance feature, searches for the caller of the other party from the telephone number included in the received signal, and Weighting factors are selected for each language, gender, and utterance feature based on the search information, and the selected weighting factors are calculated to calculate the received signal weighting factors. The received signal weighting factors are multiplied by the received signal weighting factors. In order to improve the clarity during the call, the difference between the language used and the frequency characteristics of the auditory sense, the difference in the frequency characteristics of the utterance due to gender, and the difference in the volume of the transmitted voice to the other party are improved. Can be improved.
[0049]
For example, it is generally known that auditory characteristics differ depending on the language used. Specifically, because English has a wider frequency band than Japanese (especially many high-frequency components of 2.5 kHz or more), Japanese listen to high-frequency components of 2.5 kHz or more compared to Westerners. It tends to be difficult. In the case of Japanese, it is generally known that when the high-frequency component (2.5 kHz or more) of an English tape is attenuated by the auditory characteristics, English is easier to hear than the original tape.
[0050]
By utilizing the above fact, that is, when the language used by the other party is English, it is possible to enhance the clarity by attenuating the high frequency range of the receiving audio signal divided by the BPF in the DSP. It becomes.
Even in other languages, clarity can be improved by setting parameters in consideration of the frequency characteristic difference from Japanese.
[0051]
Next, in voice correction based on gender, it is possible to improve clarity by paying attention to frequencies at which voice formants based on gender exist and setting parameters.
For example, in the case of a male utterance, the sound formant generally has a lower pitch than that of a female, so that it often sounds low and full as compared with a female. By configuring a parameter that corrects this difference in frequency characteristics, clarity during a call can be improved.
[0052]
In addition, in the correction of utterance characteristics, the level of the entire frequency band is adjusted in accordance with the characteristics of each individual utterance (large or small utterance) during a call so that the received voice level during the call can be adjusted to a certain width. Since the adjustment can be performed, it is not necessary to perform operations such as volume adjustment during a call.

Dividing the frequency band of the received signal and multiplying the level of the divided frequency band by the received signal weighting factor to correct the received signal,
According to the name and telephone number of the telephone directory, Japanese language used by the other party, information on the language used in various foreign languages, information on the gender of the other party, information on the size of the utterance of the other party as the reception parameter. Holding in advance ;
For the frequency band divided by the received signal correction unit, Japanese, a weighting factor for various foreign languages, a weighting factor for women and men , a step of holding a weighting factor for the magnitude of the utterance ,
A step of searching for a reception parameter of a caller of a communication partner held in the reception parameter holding unit from a telephone number included in a reception signal,
Based on the information of the searched reception parameter of the caller, the weight coefficient holding unit checks the language used by the caller who uses Japanese and various foreign languages, the gender of the caller, and the magnitude of the utterance of the caller. Then, the weight coefficient of the language used by the confirmed caller, the weight coefficient of the caller's gender, and the weight coefficient of the caller's utterance are selected, and the weight coefficient of the selected use language, the gender weight coefficient, and the utterance Obtaining a received signal weight coefficient by multiplying the received signal weight coefficient by a large and small weight coefficient, and multiplying the received signal by the received signal weight coefficient .
