Journal ArticleDOI
Speaker Verification Using Adapted Gaussian Mixture Models
TL;DR: The major elements of MIT Lincoln Laboratory's Gaussian mixture model (GMM)-based speaker verification system used successfully in several NIST Speaker Recognition Evaluations (SREs) are described.
Journal ArticleDOI
Speech analysis/Synthesis based on a sinusoidal representation
R.J. McAulay,Thomas F. Quatieri +1 more
TL;DR: A sinusoidal model for the speech waveform is used to develop a new analysis/synthesis technique that is characterized by the amplitudes, frequencies, and phases of the component sine waves, which forms the basis for new approaches to the problems of speech transformations including time-scale and pitch-scale modification, and midrate speech coding.
Book
Discrete-Time Speech Signal Processing: Principles and Practice
TL;DR: This chapter discusses the Discrete-Time Speech Signal Processing Framework, a model based on the FBS Method, and its applications in Speech Communication Pathway and Homomorphic Signal Processing.
Journal ArticleDOI
Energy separation in signal modulations with application to speech analysis
TL;DR: The experimental results provide evidence that bandpass-filtered speech signals around speech formants contain amplitude and frequency modulations within a pitch period, and several efficient algorithms are developed and compared for estimating the amplitude envelope and instantaneous frequency of discrete-time AM-FM signals.
Journal ArticleDOI
A review of depression and suicide risk assessment using speech analysis
Nicholas Cummins,Stefan Scherer,Jarek Krajewski,Sebastian Schnieder,Julien Epps,Thomas F. Quatieri +5 more
TL;DR: How common paralinguistic speech characteristics are affected by depression and suicidality and the application of this information in classification and prediction systems is reviewed.
