This paper uses listening tests to directly evaluate two speech pre-enhancement algorithms that were published in earlier work. The models were previously evaluated using purely objective measures. The methods under study aim to increase speech intelligibility by applying an adaptive spectral shaping filter to the speech signal. In both algorithms the shape of the filter is adapted so as to max...

We propose a framework which ports Dirichlet Gaussian mixture model (DPGMM) based labels to deep neural network (DNN). The DNN is used to extract a low-dimensional unsupervised speech representation, named as unsupervised bottleneck feature (uBNF), which captures considerable information for sound cluster discrimination. We investigate the performance of uBNF in query-by-example spoken term det...

A spoken dialog system (SDS) is a computer system which supports human-computer conversations in specific knowledge domains. It integrates technologies including speech recognition, natural language understanding, dialog modeling, language generation, and textto-speech synthesis. Advances in speech and language technologies have made SDS an important research area and have brought about systems...

Patients who use the Ineraid cochlear implant were tested in four experiments with materials which assessed frequency discrimination and speech understanding. In each experiment both frequency discrimination and speech recognition varied among patients. Correlations between the two measures were significant and ranged from 0.60 to 0.83. Most generally, frequency discrimination was better in the...

background and aim: speech understanding almost never occurs in silence. verbal communication often occurs in environments where multiple speakers are talking. in such environments, babbling noise masks speech comprehension. consonants, in comparison to vowels, are more sensitive to noise masking. consonants provide most acoustic information needed for comprehending the meaning of the word. sin...

The problem of speech/music discrimination is a challenging research problem which significantly impacts Automatic Speech Recognition (ASR) performance. This paper proposes new features for the Speech/Music discrimination task. We propose to use a decomposition of the audio signal based on wavelets, which allows a good analysis of non stationary signal like speech or music. We compute different...

Performance-based cognitive data were collected using the Cognitive Drug Research System in a study of levomilnacipran extended-release (ER) 40-120 mg/day (NCT01034462) in adults with major depressive disorder. These data were analyzed post-hoc to explore the relationship between cognitive measures, depression symptoms (Montgomery-Åsberg Depression Rating Scale, MADRS), and self-reported psycho...

It was a population based cross sectional study done with the objective of comparing some parameters (attitude & practice) of gender discrimination (GD) in rural and urban areas of Ahmedabad district. A population of 963 (446 urban & 517 rural) showed alarmingly adverse sex ratio (SR) as low as 562 among urban preschoolers. GD was prevalent in both study areas but manifested differently. Prefer...

Different speech sounds evoke unique patterns of activity in primary auditory cortex (A1). Behavioral discrimination by rats is well correlated with the distinctness of the A1 patterns evoked by individual consonants, but only when precise spike timing is preserved. In this study we recorded the speech-evoked responses in the primary, anterior, ventral, and posterior auditory fields of the rat ...
