    • A noise eliminating apparatus includes a first feature extracting block for individually extracting a feature quantity X(f) (f =1, 2, . . . , n) of an input speech containing a noise for n channels (n is an integer), and a second feature extracting block for individually extracting a feature quantity N(f) of the noise for the n channels. The apparatus also includes a noise eliminating block for deriving a first noise eliminating variable k(f) and a second noise eliminating variable d(f) from the feature quantity X(f) of the input speech containing the noise provided for each of the n channels and the feature quantity N(f) of the noise provided for each of the n channels and for generating a feature quantity S(f) of a noise-eliminated input speech in accordance with the following formula:s(f)=X(f)-k(f).N(f)-d(f).
    • 噪声消除装置包括第一特征提取块,用于单独提取包含n个信道(n为整数)的噪声的输入语音的特征量X(f)(f = 1,2,...,n) 以及第二特征提取块,用于单独提取n个信道的噪声的特征量N(f)。 该装置还包括噪声消除块,用于从包含为n中的每一个提供的噪声的输入语音的特征量X(f)导出第一噪声消除变量k(f)和第二噪声消除变量d(f) 信道和为n个信道中的每一个提供的噪声的特征量N(f),并且根据以下公式生成噪声消除的输入语音的特征量S(f):s(f)= X( f)-k(f).N(f)-d(f)。

    • A voice recognition apparatus includes a coefficient memory for storing at least one coefficient for correcting a degree of similarity which is obtained by either one of the speaker-independent recognition and the speaker-dependent recognition. The apparatus also includes a voice identification circuit for comparing the degrees of similarity of the candidates obtained by either one of the speaker-independent recognition and the speaker-dependent recognition with corrected degrees of similarity of the candidates related to the other recognition type which are obtained by performing a predetermined operation to the degree of similarity of each candidate which is supplied from the other recognition type. Then the voice identification decides one candidate having the highest degree of similarity to be an identification result.
