1. A method for dynamically selecting among text-to-speech (TTS) systems, the method comprising: synthesizing a first section of text using a first TTS system employing a first algorithm to produce a first speech waveform having an associated first score; synthesizing the first section of text using a second TTS system employing a second algorithm to produce a second speech waveform having an associated second score; normalizing, with at least one processor configured to execute a normalizing function, the first score and the second score to produce a first normalized score and a second normalized score; and selecting the first speech waveform or the second speech waveform for the first section of text based, at least in part, on a comparison of the first normalized score and the second normalized score.
2. The method as claimed in claim 1 , wherein the first score and the second score are cost function scores.
