Source sound separator with spectrum analysis through linear combination and method therefor. BACKGROUND OF THE INVENTION1. Field of the Invention. The present invention relates to a source sound separator and a method therefor, and more particularly to a source sound separator and a method for separating a target voice with an interfering sound isolated which comes from a direction other than the direction of the target voice. Description of the Background Art. Such a source sound separator is applicable to, e. In exploiting voice recognition or telephone message recording, there may be raised such a problem that the voice captured by a microphone may severely be deteriorated in precision of voice recognition by ambient noise, or that the recorded voice may become hardly perceptible due to such noise.

Under such circumstances, attempts have been made to use a microphone array to control the directivity characteristics to thereby selectively get just the voice of interest. However, simply controlling the directivity characteristics is not sufficient if it is intended to take out the voice of interest in a state separated from the background noise. The solution of controlling the directivity characteristics by a microphone array is known per se. For example, solutions for directivity characteristic control by a delayed sum array (DSA) or beam forming (BF), or for directivity characteristic control by a directionally constrained minimization of power (DCMP) adaptive array have been known to date. As solutions for separating a voice remotely uttered, there has been known a solution, termed SAFIA, in which signals output from fixed plural microphones are subject to the narrow- band spectral analysis and a microphone having yielded the maximum amplitude in each of the frequency bands is allotted to capturing sound in that frequency band, as disclosed by Japanese Patent Laid- Open Publication No. In this solution of voice separation based on bandwidth selection (BS), in order to obtain a target voice, such a microphone is selected which resides closest to a sound source uttering the target voice, and the sound in the frequency band allocated to that microphone is used to synthesize voice. In the SAFIA, described above, two signals, when overlapping, may be separated from each other. In this post, we feature some of the best sound and audio equalizer apps for Android.If there are three or more sound sources, these signals could theoretically be separated one from another whereas the performance of separation would severely be deteriorated. Thus, if there are plural noise sources, it becomes extremely difficult to separate the target sound to high precision from the received sound signal corrupted with multiple noise signals. A further solution improved over the band selection has been proposed in U. S. Patent Application Publication No. US 2. 00. 9/0. 32. A1 to Kobayashi et al. In the method taught by Kobayashi et al., as will be described in detail later on, the frequency characteristics, with which the sound signals, e. However, the signal captured by a microphone may contain an interfering sound in addition to a target sound. Hence, it cannot but be said that those solutions are improper to use in the vicinity of the last stage of elimination of the interfering sound. Under such a situation, the sound quality is deteriorated after ultimate source sound separation. SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a source sound separator and a method therefor with which, even when there are plural interfering sounds, the source sound may readily be separated with the optimum sound quality of the separated target sound. In accordance with the present invention, a source sound separator for separating a target sound and an interfering sound from each other, the interfering sound incoming from an optional direction different from the incoming direction of the target sound, comprises: a first spectrum generator for using received sound signals of two of a plurality of microphones arranged spaced apart from one another to perform first processing for linear combination for emphasizing a target sound in a time or frequency domain to thereby generate at least one first target sound predominant spectrum; a second spectrum generator for using the received sound signals of the two microphones used for generating the first target sound predominant spectrum to perform second processing of linear combination for emphasizing the target sound in the time or frequency domain to thereby generate at least one second target sound predominant spectrum; a third spectrum generator for using the received sound signals of the two microphones used for generating the first target sound predominant spectrum to perform third processing for linear combination for suppressing the target sound in the time or frequency domain to thereby generate at least one target sound suppressed spectrum which is to form a set with the first and second target sound predominant spectra; a phase generator for using received sound signals of ones of the plurality of microphones to perform processing of linear combination in the frequency domain to thereby generate a phase signal; and a target sound separator for using the first target sound predominant spectrum, the second target sound predominant spectrum, the target sound suppressed spectrum and the phase signal to separate the target sound and the interfering sound from each other. Further in accordance with the present invention, a method for separating a target sound and an interfering sound from each other, the interfering sound incoming from a direction different from a direction of the target sound incoming, comprises: preparing a first spectrum generator, a second spectrum generator, a third spectrum generator, a phase generator and a target sound separator; generating by the first spectrum generator at least one first target sound predominant spectrum by using received sound signals of two of a plurality of microphones arranged spaced apart from one another to perform first processing for linear combination for emphasizing a target sound in a time or frequency domain; generating by the second spectrum generator at least one second, target sound predominant spectrum by using received sound signals of the two microphones used for generating the first target sound predominant spectrum to perform second processing for linear combination for emphasizing the target sound in the time or frequency domain; performing by the third spectrum generator processing for linear combination for suppressing the target sound in the time or frequency domain by using the received sound signals of the two microphones used for generating the first target sound predominant spectrum to thereby generate at least one target sound suppressed spectrum which is to form a set with the first and second target sound predominant spectra; performing by the phase generator processing of linear combination in the frequency domain by using received sound signals of ones of the plurality of microphones to thereby generate a phase signal; and separating by the target sound separator the target sound and the interfering sound from each other by using the first target sound predominant spectrum, the second target sound predominant spectrum, the target sound suppressed spectrum and the phase signal. In accordance with the present invention, a computer program is provided which controls a computer, when installed in and executed on the computer, to separate a target sound and an interfering sound from each other by causing the computer to operate as the source sound separator stated above. According to the present invention, a source sound may thus readily be separated even when there are plural interfering sounds. In addition, the target sound as separated may be of optimum sound quality.
