1. Speech synthesis apparatus comprising:

  • a language generator arranged to be responsive to semantic input information indicative of at least the content of a desired speech output, to generate a corresponding text-form utterance;

    a text-to-speech converter for converting text-form utterances received from the language generator into speech form; and

    an assessment arrangement for assessing overall quality of the speech form produced by the text-to-speech converter from an input text-form utterance whereby to selectively produce an inadequacy indicator in response to the assessment arrangement determining that the current speech form is of inadequate overall quality, the language generator being arranged to respond to the assessment arrangement producing one of said inadequacy indications, to generate from the same said semantic input information, and without corrective input from the assessment arrangement, a new but differently worded version of the text-form utterance concerned.
