Guidelines to assessment of speech synthesis systems for Chinese
Shiwei Dong · 声学学报(英文版) · 1998
National assessment of speech synthesis systems for Chinese has been regularly carried out since 1994 in China. New guidelines to the assessment activities which aim at promoting the assessment work to be standardizable, automatizable (partially) and accessible to the public by computer network were set up in 1997. Two modules. the phonetic module and the linguistic module, are evaluated individually. The phonetic module is evaluated by using speech intelligibility tests at three levels:syllable, word and sentence, and speech natu-ralness tests (in MOS). As for the linguistic module, the text processing ability, which includes word segmentation, polyphonic characters, numerals, years, symbols and metrological units, is examined automatically.
