This paper describes a Unit Selection system based on diphones that was developed by the Speech Technology Group of the Enginyeria Arquitectura La Salle School, Universitat Ramon Llull. This system works with a PSOLA synthesiser for Catalan language which is used in an Oral Synthesised Message Editor (EMOVS) and Windows applications developed using Microsoft SAPI. Some common questions about Unit Selection are formulated in order to find solutions and achieve a better segmental speech quality.
