Speech delay atau keterlambatan dalam berbicara merupakan masalah yang cukup serius harus segera ditangani karena salah satu penyebab gangguan perkembangan paling sering ditemukan pada anak. (Saputra & Kuntarto, 2020). Dalam penelitian ini, penulis menjabarkan tentang permasalahan terlambat bicara, Leung Kao (1999) ungkapkan bahwa bicara mungkin memiliki dampak signifikan kehidupan pribadi,...

Objectives: This study aimed at adapting and examining the applicability of the Teach-Model-Coach-Review model of the enhanced milieu teaching (EMT) approach for improving Iranian mothers’ language strategies while interacting with their toddlers with expressive language delay. Methods: In a single-subject multiple-baseline across-behavior study, the mothers of 3 toddlers with expressive langu...

In this paper, we propose an approach for separating speech of individual speakers from a multispeaker speech signal using excitation source information. The proposed approach is demonstrated in a two-microphone case. The main issue in the two-microphone case is the estimation of delay of each speaker. We propose a method for delay estimation in multispeaker case using the knowledge of excitati...

Higher-order statistics can be used for time delay estimation (TDE) to suppress spatially correlated Gaussian noise, since the higher-order cumulant of Gaussian signal is always zero. However, third-order statistics is invalid for those signals with zero skewness, speech signal as a typical one. In this paper, the fourth-order cumulant (FOC) spectrum is derived, based on which a TDE algorithm t...

Purpose The goal of this article (PM I) is to describe the rationale for and development of the Pause Marker (PM), a single-sign diagnostic marker proposed to discriminate early or persistent childhood apraxia of speech from speech delay. Method The authors describe and prioritize 7 criteria with which to evaluate the research and clinical utility of a diagnostic marker for childhood apraxia ...

A widely used method to determine the a priori SNR from noisy speech is the decision directed (DD) approach, but the a priori SNR follows the a posteriori SNR with a delay of one frame in speech frames. As a consequence, the performance of the noise reduction system degrades. In order to overcome this artifact, we propose three computationally simple and efficient two-step methods based on the ...

In this paper, a low delay 16 kb/s wideband speech coder with a buffering delay of 1.25 ms is introduced. This coder is basically inspired from the G.728 LD-CELP standard for narrowband speech signals. Our main goal is to reduce the implementation complexity of our wideband G728 – like coder, which is mainly due to the search of the optimal excitation (gain-shape) in codebook. For this reason a...

In this letter, we address the issue of determining the number of speakers from multispeaker speech signals collected simultaneously using a pair of spatially separated microphones. The spatial separation of the microphones results in time delay of arrival of speech signals from a given speaker. The differences in the time delays for different speakers are exploited to determine the number of s...
