Combating Echo in Speech Circuits with Long Delay

Computer speech echo-corrector

The “Echo” method, elaborated by Adamczyk, which is commonly applied in many logopaedic clinics, requires the use of the delayed auditory feedback. The devices which perform this task may nowadays be replaced with a typical computer equipped with a sound set and delaying programme. In the article the authors present a real-time application, implemented on the basis of standard sound functions s...

Auditory Brainstem Response Wave Amplitude Characteristics as a Diagnostic Tool in Children with Speech Delay with Unknown Causes

Speech delay with an unknown cause is a problem among children. This diagnosis is the last differential diagnosis after observing normal findings in routine hearing tests. The present study was undertaken to determine whether auditory brainstem responses to click stimuli are different between normally developing children and children suffering from delayed speech with unknown causes. In this cr...

Digital Circuits Delay Analysis

The speed of digital circuit is one of the most restricting factors in the deep sub-micron and multigigahertz integrated circuits design. It is directly dependent on the circuit delay. Scaling down the technologies and increasing the operational frequency make the delay problems more important. This paper studies the delay in digital circuits, starting from the design process, scaling down the ...

Speech Production-Perception Relationships in Children with Speech Delay

This study examines the relationship between speech perception and speech production in children with speech delay (SD). Sixtythree children who participated in the Nemours Genetics of Speech Delay Project were categorized as either typically developing (TD) or SD. The children with SD were subgrouped by their articulation errors on the /s/ and // sounds tested in a perception experiment. An i...
