Automatic speaker recognition system based on optimised machine learning algorithms

Author: Mokgonyane, TB ; Sefara, Tshephisho J ; Modipa, TI ; Manamela, MJ Date: Sep 2019 Speaker recognition is a technique that automatically identifies a speaker from a recording of their voice. Speaker recognition technologies are taking a new trend due to the progress in artificial intelligence and machine learning and have ... Read more
Context-dependent modelling of English vowels in Sepedi code-switched speech

Author: Modipa, TI ; Davel, MH ; De Wet, Febe Date: Nov 2012 When modelling code-switched speech (utterances that contain a mixture of languages), the embedded language often contains phones not found in the matrix language. These are typically dealt with by either extending the phone set or mapping ... Read more

Author: Mokgonyane, TB ; Sefara, Tshephisho J ; Manamela, MJ ; Modipa, TI ; Masekwameng, MS Date: Aug 2020 Automatic speaker recognition is the task of automatically determining or verifying the identity of a speaker from a recording of his or her speech sample and has been studied for many decades. One of the most important steps of speaker ... Read more
The effects of data size on text-independent automatic speaker identification system

Author: Mokgonyane, TB ; Sefara, Tshephisho J ; Manamela, MJ ; Modipa, TI Date: Aug 2019 Speaker recognition is a technique that automatically identifies a speaker from a recording of their speech utterance. Speaker recognition technologies are taking a new direction due to rapid progress in artificial intelligence. Research in ... Read more
HMM-based speech synthesis system incorporated with language identification for low-resourced languages

Author: Sefara, Tshephisho J ; Mokgonyane, TB ; Manamela, MJ ; Modipa, TI Date: Aug 2019 Text-to-speech (TTS) synthesis systems are of benefit towards learning new or foreign languages. These systems are currently available for various major languages but not available for low-resourced languages. Scarcity of these systems may ... Read more
Implications of Sepedi/English code switching for ASR systems

Author: Modipa, TI ; Davel, MH ; De Wet, Febe Date: Dec 2013 Code switching (the process of switching from one language to another during a conversation) is a common phenomenon in multilingual environments. Where a minority and dominant language coincide, code switching from the minority language to ... Read more
