Articulatory speech synthesis from static context-aware articulatory targets
Speaker: Anastasiia Tsukanova Date: April 6, 2017 Abstract: In this talk I will present my work that has been carried out in the domain of articulatory speech synthesis — that is, synthesizing speech through simultaneous control over the articulators (the jaw, the tongue, the lips, the velum, the larynx and the epiglottis) and the source. It …

Automatic analysis of user’s social cues during mediated communication
Speaker: Nathan Libermann Date: March 16, 2017 Abstract: In this talk I will present the results of my master internship. I propose to explore the social cues expressed by a user during a mediated communication either with an embodied conversational agent or with another human. For this purpose, I have exploited a machine learning method to …

Supervised group nonnegative matrix factorisation with similarity constraints and applications to speaker identification
Speaker: Romain Serizel Date: February 9, 2017 Abstract: This paper presents supervised feature learning approaches for speaker identification that rely on nonnegative matrix factorisation. Recent studies have shown that group nonnegative matrix factorisation and task-driven supervised dictionary learning can help performing effective feature learning for audio classification problems. This paper proposes to integrate a recent method …

Time-frequency masking and Optimal Wiener filter for multichannel speech enhancement
Speaker: Ziteng Wang Date: December 8, 2016 Abstract: Time-frequency speech presence probability estimation or mask estimation is crucial in speech enhancement. It is especially the case in Multichannel Wiener Filter (MWF), of which the solution only relies on the second-order statistics of speech and noise. For the estimation methods, there has been a shift from experimental thresholding on multichannel features to …

Speaker Recognition: Current Challenges and Trends
Speaker: Dayana Ribas Date: November 3, 2016 Abstract: Currently there is an increasing interest in the development of technologies that integrate biometric systems due to its wide use in applications where the identification of individuals is required. In this context, Automatic Speaker Recognition Systems are in high demand from both commercial to security applications, and therefore …

Feature learning based on nonnegative matrix factorisation for speaker identification
Speaker: Romain Serizel Date: September 29, 2016 Abstract: The main target of speaker identification is to assert whether or not the speaker in an audio recording is known and if he/she is known, to find his/her identity. A recent trend is to use feature learning based approaches to overcome the limitations of hand-craft features. This talk …

City-identification of Flickr videos using semantic acoustic features
Speaker: Benjamin Elizalde (Carnegie Mellon University) Date: July 7, 2016 Abstract: City-identification of videos aims to determine the likelihood of a video belonging to a set of cities. In this paper, we present an approach using only audio, thus we do not use any additional modality such as images, user-tags or geo-tags. In this manner, we show …

Multimodal acquisition platform
Speaker: Valerian Girard (Engineer) Date: June 23, 2016 Abstract: In this talk, I will present my work during this year where I have contributed in developing a multimodal acquisition platform that records multimodal data in speech communication context. The platform can record motion capture data of the face, the arms and hands with and without markers using …
