In this work we introduce the efforts done to build a unit selection based Arabic speech synthesis voice with emotional effects. Three emotional sates were covered; normal, sad and questions. Pitchmarking enhancements have been carried out for Arabic voice building for more accurate unit concatenation. The Expressive information was employed in the proposed target cost to produce more natural and emotive synthetic speech. The system is evaluated according to the naturalness and emotiveness of the produced speech. The system evaluations show significant increase in the naturalness and emotiveness scores.

Recommender systems can help users find information by providing them with personalized suggestions. In this paper we introduce content-based recommender system TayaRecSys that suggests new stories for users in Yahki.com website. The system uses the same infrastructure of a simple search application. It is based on Lucene framework search engine. While in this work, our main focus remains on story recommendations, the proposed methods are quite general, and may apply to a wide variety of applications especially with rich text contents. The test results seem to indicate that the suggestions that TayaRecSys makes is mostly relevant.
