    • Auditory representation learning 

      Sailor, Hardik B. (Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
      Representation learning (RL) or feature learning has a huge impact in the field of signal processing applications. The goal of the RL approaches is to learn the meaningful representation directly from the data that can be ...

    • Crying for a reason : a signal processing based approach for infant cry analysis and classification 

      Chittora, Anshu (Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
      The present work in this thesis is directed towards understanding the reason of crying of an infant using signal processing approaches. Infant cry analysis and classification is a non-invasive method of analyzing the infant ...

    • Design of countermeasures for spoofed speech detection system 

      Patel, Tanvina (Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
      Automatic Speaker Verification (ASV) systems are vulnerable to speech synthesisand voice conversion techniques due to spoofing attacks.Recently, to encourage thedevelopment of anti-spoofing measures or countermeasures for ...

      Madhavi, Maulik C. (Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
      The retrieval of the spoken document and detecting the query (keyword) within the audio document have attained huge research interest. The problem of retrieving audio documents and detecting the query (keyword) using a ...

    • Design of spoof speech detection system : teager energy-based approach 

      Kamble, Madhu R. (Dhirubhai Ambani Institute of Information and Communication Technology, 2021)
      Automatic Speaker Verification (ASV) systems are vulnerable to various spoofing attacks, namely, Speech Synthesis (SS), Voice Conversion (VC), Replay, and Impersonation. The study of spoofing countermeasures has become ...

    • Voice conversion: alignment and mapping perspective 

      Shah, Nirmesh J. (Dhirubhai Ambani Institute of Information and Communication Technology, 2019)
      Understanding how a particular speaker is producing speech, and mimicking one's voice is a difficult research problem due to the sophisticated mechanism involved in speech production. Voice Conversion (VC) is a technique ...
