Single microphone speech separation by diffusion-based HMM estimation
We present a novel non-iterative and rigorously motivated approach for estimating hidden Markov models (HMMs) and factorial hidden Markov models (FHMMs) of high-dimensional signals. Our approach utilizes the asymptotic properties of a spectral, graph-based approach for dimensionality reduction and manifold learning, namely the diffusion framework. We exemplify our approach by applying it to the...
متن کاملModel-based speech separation with single-microphone input
Prior knowledge of familiar auditory patterns is essential for separating sound sources in human auditory processing. Speech recognition modeling is one probabilistic way for capturing these familiar auditory patterns. In this paper we focus on separating speech sources with a single-microphone input only. A model-based algorithm is proposed to generate target speech by estimating its spectral ...
متن کاملSingle-Microphone Speech Separation: The use of Speech Models
Separation of speech sources is fundamental for robust communication. In daily conversations, signals reaching our ears generally consist of target speech sources, interference signals from competing speakers and ambient noise. Take an example, talking with someone in a cocktail party and making a phone call in a train compartment. Fig. 1 shows a typical indoor environment having multiple sound...
متن کاملLarge-margin conditional random fields for single-microphone speech separation
Conditional random field (CRF) formulations for singlemicrophone speech separation are improved by large-margin parameter estimation. Speech sources are represented by acoustic state sequences from speaker-dependent acoustic models. The large-margin technique improves the classification accuracy of acoustic states by reducing generalization error in the training phase. Non-linear mappings inspi...
متن کاملHMM-separation-based speech recognition for a distant moving speaker
This paper presents a hands-free speech recognition method based on HMM composition and separation for speech contaminated not only by additive noise but also by an acoustic transfer function. The method realizes an improved user interface such that a user is not encumbered by microphone equipment in noisy and reverberant environments. The use of HMM composition has already been proposed for co...
