This paper presents three new speech databases for standard Basque.They are designed primarily for corpus-based synthesis but each database has its specific purpose: 1) AhoSyn: high quality speech synthesis (recorded also in Spanish), 2) AhoSpeakers: voice conversion and 3) AhoEmo3: emotional speech synthesis.The whole corpus design and the recording process are described with detail.Once the databases were collected all the data was automatically labelled and annotated.Then, an HMM-based TTS voice was built and subjectively evaluated.The results of the evaluation are pretty satisfactory: 3.70 MOS for Basque and 3.44 for Spanish.Therefore, the evaluation assesses the quality of this new speech resource and the validity of the automated processing presented.
