    • A Hybrid Method Oriented to Concatenative Text-to-Speech Synthesis 

      Iriondo Sanz, Ignasi; Alías Pujol, Francesc; Sanchís Bernabeu, Francisco Javier; Melenchón Maldonado, Javier (2003-09-01)
      In this paper we present a speech synthesis method for diphonebased text-to-speech systems. Its main goal is to achieve prosodic modifications that result in more natural-sounding synthetic speech. This ...

    • A Pitch Marks Filtering Algorithm Based on Restricted Dynamic Programming 

      Alías Pujol, Francesc; Monzó Sánchez, Carlos; Socoró Carrié, Joan Claudi (2006-09-17)
      In this paper, a generic pitch marks filtering algorithm (PMFA) is introduced in order to achieve reliable and smooth pitch marks from any input pitch tracking or marking algorithm. The proposed PMFA ...

      Este artículo resume la trayectoria del grupo de Tecnologías del Habla de Ingeniería La Salle (Universitat Ramon Llull) en el marco de la investigación y el desarrollo de sistemas de síntesis del habla. ...

    • Evolutionary weight tuning based on diphone pairsfor unit selection speech synthesis 

      Alías Pujol, Francesc; Llorà Fàbrega, Xavier (2003-09-01)
      Unit selection text-to-speech (TTS) conversion is an ongoingresearch for the speech synthesis community. This paper isfocused on tuning the weights involved in the target and con-catenation cost metrics. ...

    • GTM-URL Contribution to the INTERSPEECH 2009 Emotion Challenge 

      Planet García, Santiago; Iriondo Sanz, Ignasi; Socoró Carrié, Joan Claudi; Monzo Sánchez, Carlos; Adell, Jordi (2009-09)
      This paper describes our participation in the INTERSPEECH 2009 Emotion Challenge [1]. Starting from our previous experience in the use of automatic classification for the validation of an expressive ...

    • HMM-based Spanish speech synthesis using CBR as F0 estimator
