摘要
In a phoneme recognition apparatus, first distances between input vectors and reference vectors are determined. If the first distances are lower than a threshold value, the input vectors are identified as corresponding to the reference vectors. If the first distances are higher than the threshold value, the input vectors are identified as being indeterminate, and input differential vectors between the input vectors identified as corresponding to a reference vector and those identified as not corresponding to any of the reference vectors are determined. In addition, reference differential vectors between the reference vectors having corresponding input vectors and are those having no corresponding input vectors are determined. Second distances between the input differential vectors and the reference differential vectors are calculated and summed. The indeterminate input vectors are then identified as corresponding to the reference vectors in accordance with combined values of the first distances and the summed second distances.
