PURPOSE The purpose of this article was to understand the experience of speech impairment (speech sound disorders) in everyday life as described by children with speech impairment and their communication partners. METHOD Interviews were undertaken with 13 preschool children with speech impairment (mild to severe) and 21 significant others (family members and teachers). RESULTS A phenomenolo...

A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...

Speech Activity Detection(SAD) is a well researched problem for communication, command and control applications, where audio segments are short duration and solution proposed for noisy as well as clean environments. In this study, we investigate the SAD problem using NASA’s Apollo space mission data [1]. Unlike traditional speech corpora, the audio recordings in Apollo are extensive from a long...

While human listeners excel at selectively attending to a conversation in a cocktail party, machine performance is still far inferior by comparison. We show that the cocktail party problem, or the speech separation problem, can be effectively approached via structured prediction. To account for temporal dynamics in speech, we employ conditional random fields (CRFs) to classify speech dominance ...

Objective: It is extremely common for adults to use inner speech to regulate their behavior. Despite this, little is known about the underlying processes that may explain why people use inner speech differently. This study aimed to determine the relationship between different types of inner speech with symptoms of anxiety, depression, somatization, and distress in normal people. Methods: The r...
