  • Glottal Spectral Separation for Parametric Speech Synthesis 

    Renals, Steve; Yamagishi, Junichi; Richmond, Korin; Cabral, Joao P (2008)
    This paper presents a method to control the characteristics of synthetic speech flexibly by integrating articulatory features into a Hidden Markov Model (HMM)-based parametric speech synthesis system. In contrast to model ...
  • Goal-Directed ASR in a Multimedia Indexing and Searching Environment (MUMIS) 

    Wester, Mirjam; Kessens, Judith M; Strik, Helmer (International Speech Communication Association, 2002-09)
    This paper describes the contribution of automatic speech recognition (ASR) within the framework of MUMIS (Multimedia Indexing and Searching Environment). The domain is football commentaries. The initial results of carrying ...
  • Growing bottleneck features for tandem ASR 

    Frankel, Joe; Wang, Dong; King, Simon (2008)
    We present a method for training bottleneck MLPs for use in tandem ASR. Experiments on meetings data show that this approach leads to improved performance compared with training MLPs from a random initialization.
  • Habitable Cars: what we do there 

    Laurier, Eric; Brown, Barry; Lorimer, Hayden (Institute of Geography; The School of Geosciences; The University of Edinburgh, 2005)
    Two seats and a small sofa all facing forwards. The three piece suite of the conventionally designed car. A little living room. It is supplied with a stereo for playing music and a radio. More commonly now, DVD players ...
  • Health and Privacy: The Experience of a Regulator 

    Anderson, Ken (AHRC Research Centre for Studies in Intellectual Property and Technology Law, 2005-09)
    Paper presented by Anderson for the Privacy Workshop, chaired by Edwards and held in September 2005.
  • Heat and Mass Transfer in Fires: Scaling Laws and their Application 

    Torero, Jose L (2005-10)
    Fire is a phenomenon that covers a multiplicity of scales depending on the different processes involved. Length scales range from the nanometres when addressing material flammability to the kilometres when dealing with ...
  • The Helpful Environment: distributed agents and services which cooperate 

    Tate, Austin (Springer, 2006-09)
    Imagine a future environment where networks of agents - people, robots and software agents - interact with sophisticated sensor grids and environmental actuators to provide advice, protection and aid. The systems will be ...
  • Hidden Markov Model for Automatic Transcription of MIDI Signals 

    Takeda, Haruto; Saito, Naoki; Otsuki, Tomoshi; Nakai, Mitsuru; Shimodaira, Hiroshi; Sagayama, Shigeki (IEEE, 2002-12)
    This paper describes a Hidden Markov Model (HMM)-based method of automatic transcription of MIDI (Musical Instrument Digital Interface) signals of performed music. The problem is formulated as recognition of a given sequence ...
  • Hierarchical dialogue optimization using semi-markov decision processes. 

    Cuayáhuitl, Heriberto; Renals, Steve; Lemon, Oliver; Shimodaira, Hiroshi (2007)
    This paper addresses the problem of dialogue optimization on large search spaces. For such a purpose, in this paper we propose to learn dialogue strategies using multiple Semi-Markov Decision Processes and hierarchical ...
  • HMM Adaptation and Voice Conversion for the Synthesis of Child Speech: A Comparison 

    Watts, Oliver; Yamagishi, Junichi; King, Simon; Berkling, Kay (2009)
    This study compares two different methodologies for producing data-driven synthesis of child speech from existing systems that have been trained on the speech of adults. On one hand, an existing statistical parametric ...
  • HMM-based Speech Synthesis with an Acoustic Glottal Source Model 

    Cabral, Javier; Renals, Steve; Richmond, Korin; Yamagishi, Junichi (2009)
    A major cause of degradation of speech quality in HMM-based speech synthesis is the use of a simple delta pulse signal to generate the excitation of voiced speech. This paper describes a new approach to using an acoustic ...
  • HMM-based synthesis of child speech 

    Watts, Oliver; Yamagishi, Junichi; Berkling, Kay; King, Simon (2008)
    The synthesis of child speech presents challenges both in the collection of data and in the building of a synthesiser from that data. Because only limited data can be collected, and the domain of that data is constrained, ...
  • HMM-based Text-to-Articulatory-Movement Prediction and Analysis of Critical Articulators 

    Ling, Zhen-Hua; Richmond, Korin; Yamagishi, Junichi (2010)
    In this paper we present a method to predict the movement of a speaker's mouth from text input using hidden Markov models (HMM). We have used a corpus of human articulatory movements, recorded by electromagnetic articulography ...
  • The HTS-2008 System: Yet Another Evaluation of the Speaker-Adaptive HMM-based Speech Synthesis System in The 2008 Blizzard Challenge 

    Yamagishi, Junichi; Zen, Heiga; Wu, Yi-Jian; Toda, Tomoki; Tokuda, Keiichi (2008)
    For the 2008 Blizzard Challenge, we used the same speaker-adaptive approach to HMM-based speech synthesis that was used in the HTS entry to the 2007 challenge, but an improved system was built in which the multi-accented ...
  • Human Rights, Intellectual Property and Competition Law: From Fragmentation to Coherence
