Pitchnet: Unsupervised Singing Voice Conversion with Pitch Adversarial Network

ICASSP 2020accepted

Singing voice conversion is to convert a singer's voice to another one's voice without changing singing content. Recent work shows that unsupervised singing voice conversion can be achieved with an autoencoder-based approach [1]. However, the converted singing voice can be easily out of key, showing…

Seq2Seq Attentional Siamese Neural Networks for Text-dependent Speaker Verification

ICASSP 2019accepted

In this paper, we present a Sequence-to-Sequence Attentional Siamese Neural Network (Seq2Seq-ASNN) that leverages temporal alignment information for end-to-end speaker verification. In prior works of speaker discriminative neural networks, utterance-level evaluation/enrollment speaker representation…

Unsupervised Speech Recognition via Segmental Empirical Output Distribution Matching

ICLR 2019poster

We consider the problem of training speech recognition systems without using any labeled data, under the assumption that the learner can only access to the input utterances and a phoneme language model estimated from a non-overlapping corpus. We propose a fully unsupervised learning algorithm that a…

Context adaptive deep neural networks for fast acoustic model adaptation in noisy conditions

ICASSP 2016accepted

Deep neural network (DNN) based acoustic models have greatly improved the performance of automatic speech recognition (ASR) for various tasks. Further performance improvements have been reported when making DNNs aware of the acoustic context (e.g. speaker or environment) for example by adding auxili…

Language recognition using deep neural networks with very limited training data

ICASSP 2016accepted

This study proposes a novel deep neural network (DNN) based approach to language identification (LID) for the NIST 2015 Language Recognition (LRE) i-Vector Machine Learning Challenge. State-of-the-art DNN based LID systems utilize large amounts of labeled training data. The 2015 LRE i-Vector Machine…

UTD-CRSS system for the NIST 2015 language recognition i-vector machine learning challenge

ICASSP 2016accepted

In this paper, we present the system developed by the Center for Robust Speech Systems (CRSS), University of Texas at Dallas, for the NIST 2015 language recognition i-vector machine learning challenge. Our system includes several subsystems, based on Linear Discriminant Analysis - Support Vector Mac…
