Automatic stylization, coding and modelling of intonation in text-to-speech for under-resourced languages

Author: Louw, Johannes A ; Moodley, Avashlin Date: Dec 2017 In this paper an automatic method to implicitly model intonation for statistical parametric speech synthesis (SPSS) is presented. The approach is ideally suited to single speaker speech databases as used in text-to-speech (TTS), due to the ... Read more
Building synthetic voices for under-resourced languages: a comparison between audiobook and studio data

Author: De Wet, Febe ; Dlamini, Nkosikhona ; Van der Walt, Willem J ; Govender, Avashna Date: Dec 2017 Creating synthetic voices that are both natural and intelligible is a daunting challenge for well-resourced languages. The challenge is much bigger for languages in which the speech and text resources required for voice development are not ... Read more
Grammar-driven text-to-speech application for articulation of mathematical expressions

Author: Mogale, MM ; Sefara, Tshephisho J ; Mokgonyane, TB Date: Sep 2020 Natural Language Processing (NLP) forms one of the important and fundamental components of speech synthesis while a language grammar forms one of the important requirements for NLP tasks. One of the major requirements in processing speech ... Read more
Intonation model for TTS in Sepedi

Author: Van Niekerk, DR ; Barnard, E Date: Sep 2010 The authors present an initial investigation into the acoustic realisation of tone in continuous utterances in Sepedi (a language in the Southern Bantu family). An analytic model for the generation of appropriate pitch contours given an ... Read more
Predicting utterance pitch targets in Yoruba for tone realisation in speech synthesis

Author: Van Niekerk, DR ; Barnard, E Date: 2013 Pitch is a fundamental acoustic feature of speech and as such needs to be determined during the process of speech synthesis. While a range of communicative functions are attributed to pitch variation in speech of all languages, it plays a ... Read more
The Speect text-to-speech system entry for the Blizzard Challenge 2013

Author: Louw, Johannes A ; Schlunz, Georg I ; Van der Walt, W ; De Wet, Febe ; Pretorius, L Date: Sep 2013 This paper describes the speect text-to-speech system entry for the Blizzard Challenge 2013. The techniques applied for the tasks of the challenge are described as well as the implementation details for the alignment of the audio books and ... Read more
Text-to-speech duration models for resource-scarce languages in neural architectures

Author: Louw, Johannes A Date: Dec 2020 Sequence-to-sequence end-to-end models for text-to-speech have shown significant gains in naturalness of the produced synthetic speech. These models have an encoder-decoder architecture, without an explicit duration model, but rather a learned ... Read more
