We describe our approach to construct a phoneme set for polyglot speech synthesis. In polyglot speech synthesis, resources are shared across languages. The goal of this research is to develop global phoneme set using existing resources. Therefore, MBROLA has been selected. In MBROLA, there are 72 diphone databases of different languages. For each database, there is a set of phonemes used. We ha...

Pronunciation training is an important part of Computer Assisted Training (CAPT) systems. Mispronunciation detection systems recognized pronunciation mistakes from user’s speech and provided them feedback about their pronunciation. Acoustic phonetic features plays a vital role in classification based applications. This research work investigated the suitability various acoustic features: pitch,...

Objectives: This paper studies the effect of Persian Cued Speech on the perception of Persian language phonemes and monosyllabic words with and without sound in hearing impaired children. Cued Speech is a sound based mode of communication for hearing impaired people that is comprised of a limited series of hand complements and the normal pattern of speech. And it is shown that it effectively ca...

Authors are under procedure to develop Gujarati Text to speech(TTS) synthesis system using concatenation of Gujarati phonemes for unrestricted input Gujarati text. In this methodology, Gujarati phonemes are needed to record and store as speech database. This paper describes a flexible procedure to develop speech database in . wav format. This method is simple to implement which uses less memory...

Abstract VocalTract.sty is a package to visualize the vocal tract. Vocal tract is manipulated by a vector of articulation parameters according to S. Maeda model. Animation can be achieved by providing a sequence of vectors over time, e.g. from Matlab®. An embedded sequence of vectors in the VocalTract.sty for certain German phonemes allows for a sequence of phonemes animation when no vector is ...

In this study, we present a pronunciation scoring method for second language learners of English (hereafter, L2 learners). This study presents a method using both confidence scoring and classifiers. Classifiers have an advantage over confidence scoring for specialization in the specific phonemes where L2 learners make frequent errors. Classifiers (Landmark-based Support Vector Machines) were tr...

This paper describes the acoustic characteristics of hesitations in Estonian spontaneous speech. We especially investigate duration, fundamental frequency, and first two formant analyses. Most frequent hesitations can be expressed by lengthened phonemes such as /ää/, /ee/, /õõ/, and /mm/. We compare lengthened phoneme hesitations with their related phonemes. The results from our preliminary hes...

OBJECTIVE Although brain-computer interfaces (BCIs) can be used in several different ways to restore communication, communicative BCI has not approached the rate or efficiency of natural human speech. Electrocorticography (ECoG) has precise spatiotemporal resolution that enables recording of brain activity distributed over a wide area of cortex, such as during speech production. In this study, ...
