On the estimation of low fundamental frequencies [PDF]

2011 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), 2011
In this paper, we analyze the difficult problem of estimating low fundamental frequencies from periodic signals, like those produced by musical instruments. The problem arises when the fundamental frequency is low for a given number of samples as this causes the harmonics to overlap in the frequency domain.

Tone Recognition of Pahari Language

Journal of Communication and Cultural Trends, 2023
Pahari is an under-resourced, endangered, and undocumented tonal language, spoken in Pakistan Administered State of the Azad Jammu and Kashmir (AJK). Preliminary studies have established the notion, that the Pahari language has three discrete level tones;

Benefits of Harmonicity for Hearing in Noise Are Limited to Detection and Pitch-Related Discrimination Tasks

Biology, 2023
Harmonic complex tones are easier to detect in noise than inharmonic complex tones, providing a potential perceptual advantage in complex auditory environments.

Tonal Contour Generation for Isarn Speech Synthesis Using Deep Learning and Sampling-Based F₀ Representation

Applied Sciences, 2020
The modeling of fundamental frequency (F0) in speech synthesis is a critical factor affecting the intelligibility and naturalness of synthesized speech. In this paper, we focus on improving the modeling of F0 for Isarn speech synthesis. We propose the F0

Localisation of defects with time and frequency measurements using pulsed arrays [PDF]

, 2014
The frequency dependent directivity of the periodic permanent magnet transducer is to used extract information about the position of any discontinuities present in a sample. Two approaches are used; narrowband excitation, and broadband pulsed generation.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

An Arduino-Based Resonant Cradle Design with Infant Cries Recognition

Sensors, 2015
This paper proposes a resonant electric cradle design with infant cries recognition, employing an Arduino UNO as the core processor. For most commercially available electric cradles, the drive motor is closely combined with the bearing on the top ...

The Impact of Pitch and Timbre Cues on Auditory Grouping and Stream Segregation

Frontiers in Neuroscience, 2022
In multi-talker listening environments, the culmination of different voice streams may lead to the distortion of each source’s individual message, causing deficits in comprehension. Voice characteristics, such as pitch and timbre, are major dimensions of

Vowel Classification Based on Fundamental Frequency and Formant Frequencies [PDF]

Journal of Speech, Language, and Hearing Research, 1993
A quadratic discriminant classification technique was used to classify spectral measurements from vowels spoken by men, women, and children. The parameters used to train the discriminant classifier consisted of various combinations of fundamental frequency and the three lowest formant frequencies.
