We present a system for generating Italian sentences from the interlingua semantic representation (Interchange Format) adopted within the C-STAR speech to speech translation project. The generation task in our application scenario is made peculiar by: i) a semantically underspecified input representation whose interpretation relies on implicit domain knowledge; ii) the spoken language output, characterized by frequent use of idiomatic forms, fragmentary phrases, etc. iii) a strong requirement for high time efficiency. We discuss how these constraints lead us to develop a template based generator providing a good trade-off betzeen flexibility and efficiency. We overcome the shortcomings of traditional static templates by using flexible templates which allow an elegant treatment of phonological adjustments, morphological agreement (very frequent in Italian) and syntactic constituency phenomena

Abstract
We present a system for generating Italian sentences from the interlingua semantic representation (Interchange Format) adopted within the C-STAR speech to speech translation project. The generation task in our application scenario is made peculiar by: i) a semantically underspecified input representation whose interpretation relies on implicit domain knowledge; ii) the spoken language output, characterized by frequent use of idiomatic forms, fragmentary phrases, etc. iii) a strong requirement for high time efficiency. We discuss how these constraints lead us to develop a template based generator providing a good trade-off betzeen flexibility and efficiency. We overcome the shortcomings of traditional static templates by using flexible templates which allow an elegant treatment of phonological adjustments, morphological agreement (very frequent in Italian) and syntactic constituency phenomenaI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
