DNN-based Speech Synthesis: Importance of input features and training data

Philip Neil Garner

Deep neural networks (DNNs) have been recently introduced in speech synthesis. In this paper, an investigation on the importance of input features and training data on speaker dependent (SD) DNN-based speech synthesis is presented. Various aspects of the t ...

Speech vocoding for laboratory phonology

Milos Cernak

In this paper, we propose a platform based on phonological speech vocoding for examining relations between phonology and speech processing, and in broader terms, between the abstract and physical structures of speech signal. The goal of this paper is to go ...

Phonological Vocoding Using Artificial Neural Networks

Philip Neil Garner, Milos Cernak

We investigate a vocoder based on artificial neural networks using a phonological speech representation. Speech decomposition is based on the phonological encoders, realised as neural network classifiers, that are trained for a particular language. The spe ...

HMM-based Non-native Accent Assessment using Posterior Features

Milos Cernak, Ramya Rasipuram

Automatic non-native accent assessment has many potential benefits in language learning and speech technologies. The three fundamental challenges in automatic accent assessment are to characterize, model and assess individual variation in speech of the non ...

Optimized Coding Strategies for Interactive Multiview Video

Ana Karina De Abreu Goes

The natural next step in improving the realistic experience in multimedia services is interactive multiview video (IMV). IMV promises to enable the users to freely navigate through a scene by selecting their preferred viewpoints from any view position for ...

Raking the Cocktail Party

Martin Vetterli, Ivan Dokmanic, Robin Scheibler

We present the concept of an acoustic rake receiver—a microphone beamformer that uses echoes to improve the noise and interference suppression. The rake idea is well-known in wireless communications; it involves constructively combining different multipath ...

Ethnography of a political ritual: speeches given to new Swiss citizens by representatives of the state

Maxime Carl Felder

Our paper examines speeches given at citizenship ceremonies in Geneva (Switzerland) in order to understand what makes a foreigner a new member of a national and especially of a cantonal entity. Focusing on speeches by three ministers over an interval of 4 ...

Raking echoes in the time domain

Martin Vetterli, Ivan Dokmanic, Robin Scheibler

The geometry of room acoustics is such that the reverberant signal can be seen as the same waveform emitted from multiple locations. In analogy with the rake receiver from wireless communications, we propose several beamforming strategies that exploit, rat ...

Towards Unconditional Tor-Like Anonymity

Christina Fragouli, László Czap, Iris Safaka

We design and evaluate a traffic anonymization protocol for wireless networks, aiming to protect against computationally powerful adversaries. Our protocol builds on recent key-generation techniques, that leverage intrinsic properties of the wireless toget ...
