In the presence of competing speech or noise, reverberation degrades speech intelligibility not only by its direct effect on the target but also by affecting the interferer. Two experiments were designed to validate a method for predicting the loss of intelligibility associated with this latter effect. Speech reception thresholds were measured under headphones, using spatially separated target ...

According to an estimation by Stengelhofen (1989), 38% of all subjects born with a cleft lip and palate (CLP) will have persistent speech defects which will require long term speech therapy. Apart from hypernasal resonance disorders, compensatory articulatory patterns are the most frequent and salient feature of CLP speech. Trost (1981) distinguishes two types of sound errors in CLP articulatio...

Introduction: Speech sound disorders (SSD) are the largest group of communication disorders observed in children requirin education services. However, to date, the neurological origin of SSD has not been researched extensively. We conducted a fu MRI (fMRI) study using the HUSH (Hemodynamics Unrelated to Sounds from Hardware) technique on 6 participants with SS of unknown etiology in comparison ...

This paper summarises work on ‘xenophones’ (foreign sounds) carried out at Telia Research. The inclusion of “foreign” sounds in Swedish is described, as well as their implications on speech recognition and speech synthesis. Results from two earlier studies are summarised and described: the nature of the expansion of what is normally regarded as the Swedish phone set, and the nature of some poss...

Studies in sleeping newborns and infants propose that the superior temporal sulcus is involved in speech processing soon after birth. Speech processing also implicitly requires the analysis of the human voice, which conveys both linguistic and extra-linguistic information. However, due to technical and practical challenges when neuroimaging young children, evidence of neural correlates of speec...
