    • Discriminative features for GMM and i-vector based speaker diarization 

      Zewoudie, Abraham Woubie (Universitat Politècnica de Catalunya, 2017-09-20)
      Doctoral thesis
      Open Access
      Speaker diarization has received several research attentions over the last decade. Among the different domains of speaker diarization, diarization in meeting domain is the most challenging one. It usually contains spontaneous ...

    • Jitter and Shimmer measurements for speaker diarization 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2014)
      Conference report
      Open Access
      Jitter and shimmer voice quality features have been successfully used to characterize speaker voice traits and detect voice pathologies. Jitter and shimmer measure variations in the fundamental frequency and amplitude ...

    • Short- and long-term speech features for hybrid HMM-i-vector based speaker diarization system 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2016)
      Conference lecture
      Open Access
      i-vectors have been successfully applied over the last years in speaker recognition tasks. This work aims at assessing the suitability of i-vector modeling within the frame of speaker diarization task. In such context, a ...

    • The use of long-term features for GMM- and i-vector-based speaker diarization systems 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2018-09-26)
      Article
      Open Access
      Several factors contribute to the performance of speaker diarization systems. For instance, the appropriate selection of speech features is one of the key aspects that affect speaker diarization systems. The other factors ...

    • Using voice-quality measurements with prosodic and spectral features for speaker diarization 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (International Speech Communication Association (ISCA), 2015)
      Conference lecture
