Optimization of acoustic feature extraction from dysarthric speech
… listener, there must be a set of consistent acoustic cues that the familiar communication partner is able to interpret. While dysarthric speech has been characterized both acoustically and perceptually, most accounts tend to compare dysarthric productions to those of healthy controls rather …

Acoustic Feature Design for Speech Recognition, a Statistical Information-Theoretic Approach
… joint conditional and unconditional PDFs of the features, and then, by relaxing these constraints, we develop a dimensionality reduction approach that maximizes the conditional mutual information between the class identity and the feature vector in the lower-dimensional space given the recognizer …

Multiview feature learning for speech recognition
… problem of learning a linear transformation of acoustic feature vectors for speech recognition, in a framework where apart from the acoustics, additional views are available at training time. We consider a multiview learning approach based on canonical correlation analysis to learn linear …

Design of tool for analysis of speech development disorders using landmarks and other acoustic cues
… we compared the modification of predicted acoustic cues to distinctive features of manner, place and voicing for just under 30 children (ages 5-12), for the CN-Rep word inventory, in an extension of the earlier analysis in Levy et al. 2014. Feature cues, including abrupt acoustic landmarks …

Model-Based Speech Enhancement
… that reconstructs clean speech from a set of acoustic features using a harmonic plus noise model of speech. This is a significant departure from traditional filtering-based methods of speech enhancement. A major challenge with this approach is to estimate accurately the acoustic features …

Emotional Prosody across languages and genders
… across languages and detect cross-linguistic acoustic markers of emotion. Additionally, it investigates how gender differences play a role in expression and recognition of emotion in speech. The computational approach is complemented by a series of acoustic feature analyses, offer- ing a dual …

Experience dependent coding of intonations by offsets in mouse auditory cortex
Acoustic communication is an important aspect of many social interactions across mammalian species. The encoding of intra-species vocalizations and plasticity mechanisms engaged during the process of learning vocalizations are poorly understood. This is particularly true with regards to how sensory …

The Phonology and Phonetics of Word-Initial Geminates
… This is due to the fact that the most salient acoustic feature for geminates,duration, may be indistinguishable when the sound is in word initial position. However, as will be shown, the production of initial geminates in Cypriot allows listeners to correctly discriminate between initial …

Data-Centric Machine Learning for Speech and Audio
… We demonstrate methods for sampling the acoustic feature space and selecting highly informative and diverse examples to build models with highly limited data. Second, we present data selection methods that apply domain knowledge for a speech enhancement system. We demonstrate that …

Evaluation of content-based acoustic features for musical genre classification
In this thesis, we evaluate content-based acoustic features for musical genre classification. Effectiveness of various acoustic features are compared using a k-nearest neighbor (KNN) classifier. By utilizing the combinations of acoustic features, an average classification accuracy of $89\%$ for …

Statistical and Biological Analyses of Acoustic Signals in Estrildid Finches
<p>Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication …
