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...

In this paper, we focus on speech recognition using multiple microphones with varying quality. The quality of one channel may be much better than other channels and even the output of standard microphone array techniques such as the delay-and-sum beamformer. Therefore, it is important to find a good indicator to select a channel for recognition. This paper introduces Decoder-Based Channel Selec...

In the area of speech signal processing, real background noise is important problem for noise reduction, therefore more skillful methods are required in this area. Accordingly, this paper proposes a spectrum recovery algorithm using a signal-to-noise ratio classification method based on a classification of a voiced or unvoiced signal. Therefore, the proposed algorithm recovers a speech spectrum...

Speech by one or more interlocutors may be described as continuous, but a moment's reflection will reveal that it is not really continuous at all. Minimally, speakers must break off their speech to breathe. In extreme cases, their speech may become highly discontinuous, with long breaks, extraneous sounds or words, or reformulations that cause delay in message transfer. These kinds of discontin...

In this paper, we present an algorithm for Voice Activity Detection (VAD) in speech signals using the minimum phase group delay function. The proposed method considers a buffer consisting of contiguous frames of the given signal and computes the short-term energy (STE) for that buffer. By appending a surrogate signal to STE and viewing the resultant signal as a positive part of the magnitude sp...

Quality models predict the perceptual quality of services as they calculate subjective ratings from measured parameters. In this paper we present a new quality model that evaluates VoIP telephone calls in order to control their transmission at run-time. In addition to packet loss rate, coding mode and delay it takes into account the impairments due to changes in the transmission con guration (e...

Converging evidence supports the hypothesis that the most common subtype of childhood speech sound disorder (SSD) of currently unknown origin is genetically transmitted. We report the first findings toward a set of diagnostic markers to differentiate this proposed etiological subtype (provisionally termed speech delay-genetic) from other proposed subtypes of SSD of unknown origin. Conversationa...

Review Executive summary: Screening for speech and language delay: a systematic review of the literature

Some of the major challenges for interactive and streaming multimedia applications are the delay and delay jitter of today’s IP packet networks. In this paper, we present the implementation, on the STMicroelectronics NomadikTM multimedia processor family, of an advanced playout scheduling scheme that achieves high robustness against late packets while maintaining very low buffering delay at the...

Not all children with speech delay (SD) of unknown origin develop fully normal speech even with intervention. Many retain residual distortion errors into adolescence and ultimately into adulthood. The current study examined whether articulation rate distinguishes those children who retain residual errors from those who normalize. Two groups of speech-delayed children originally identified at pr...
