Distinctive acoustic changes in speech in Parkinson's disease
AbstractDysarthria occurs in the early stage of Parkinson's disease (PD), and the pronunciation of speech sounds is significantly different between PD patients and healthy subjects. However, the formant frequencies of different syllables as vocalized by ...

Performance Analysis of Kannada Phonetics: Vowels, Fricatives and Stop Consonants Using LP Spectrum
AbstractKannada is an alpha syllabary language wherein each individual akshara/alphabet having different phonetic structures can be divided into sequence of numerous consonants and vowels. In our analysis, we concentrate on vowels, fricatives and stop ...

Acoustic Characterization of Amharic Vowel Sound Units
SSPS '19: Proceedings of the 2019 International Symposium on Signal Processing SystemsPages 36–40https://doi.org/10.1145/3364908.3365289Acoustic characterization of vowels has a significant role in the development of speech synthesis and recognition systems. Specifically, it reduces the improper vowel parameter selection for the concatenative and formant based speech synthesis systems. ...

Assessment on impact of various types of dysarthria on acoustic parameters of speech
International Journal of Speech Technology (SPIJST), Volume 21, Issue 3Pages 705–714https://doi.org/10.1007/s10772-018-9539-0Dysarthria is one of the major speech impairments that makes speech unintelligible and inaudible. It is a motor speech disorder which occurs due to neurological injury to the motor-speech system and an indication of this is a poor articulation of ...

Analysis of Polish Nasalized Vowels Based on Spatial Energy Distribution and Formant Frequency Measurement
Human Language Technology. Challenges for Computer Science and LinguisticsPages 186–196https://doi.org/10.1007/978-3-030-66527-2_14AbstractIn this paper, we discuss the results of the analysis of F1 and F2 frequency measurements in Polish nasalized vowels represented in writing by the graphemes ę and ą (realized before voiceless fricatives). The speech material included recordings of ...

Formant position based weighted spectral features for emotion recognition
Speech Communication (SPCO), Volume 53, Issue 9-10Pages 1186–1197https://doi.org/10.1016/j.specom.2011.04.003In this paper, we propose novel spectrally weighted mel-frequency cepstral coefficient (WMFCC) features for emotion recognition from speech. The idea is based on the fact that formant locations carry emotion-related information, and therefore critical ...
