1. A speech synthesis apparatus comprising:

  • a speech parameter database configured to store a plurality of parameters respectively corresponding to speech synthesis units constituting a speech file;

    an input unit configured to receive a text including a plurality of speech synthesis units; and

    a processor configured toselect a plurality of candidate unit parameters respectively corresponding to the plurality of speech synthesis units included in the received text, from the plurality of parameters stored in the speech parameter database,generate a parameter unit sequence of a partial or entire portion of the text according to probability of concatenation between consecutively concatenated candidate unit parameters of the selected plurality of candidate unit parameters, andperform a synthesis operation based on a hidden Markov model (HMM) using the parameter unit sequence and thereby generate an acoustic signal corresponding to the text.
