This contribution gives an overview of the performance evaluation of our text-to-speech conversion system for Spanish. This rule-based system comprises both a linguistic and a phonetic component. The performance test involved the linguistic output as well as the phonetic output. The linguistic output (which shows the workings of rules concerning grapheme-to-phoneme conversion, assimilation, word stress, syllabification, and intonation) was checked on the basis of a small text corpus. The phonetic output, i.e. the synthesized speech, was tested with respect to intelligibility and naturalness, using both an expert and naive listeners.
