    constructing a splice file dictionary including every word and every word sequence for the splice phrases and including a phone sequence associated with every word and every word sequence for the splice phrases;

    providing input to be acoustically produced;

    comparing the input to training data in the splice file dictionary to identify one of words and word sequences corresponding to the input for constructing a phone sequence;

    comparing the input to a pronunciation dictionary when the input is not found in the training data of the splice file dictionary;

    identifying a segment sequence using a first search algorithm to construct output speech according to the phone sequence; and

    concatenating segments of the segment sequence and modifying characteristics of the segments to be substantially equal to requested characteristics.
