  abstract = {As we articulate speech, we usually move the head and exhibit various facial expressions. This visual aspect of speech aids understanding and helps communicating additional information, such as the speaker's mood. In this paper we analyze quantitatively head and facial movements that accompany speech and investigate how they relate to the text's prosodic structure. We recorded several hours of speech and measured the locations of the speaker's main facial features as well as their head poses. The text was evaluated with a prosody prediction tool, identifying phrase boundaries and pitch accents. Characteristic for most speakers are simple motion patterns that are repeatedly applied in synchrony with the main prosodic events. Direction and strength of head movements vary widely from one speaker to another, yet their timing is typically well synchronized with the spoken text. Understanding quantitatively the correlations between head movements and spoken text is important for synthesizing photo-realistic talking heads. Talking heads appear much more engaging when they exhibit realistic motion patterns.},

  title = {Estimating Articulatory Parameters from the Acoustic Speech Signal},
  abstract = {A successful method for inferring articulation from the acoustic speech signal would find many applications: low bit-rate speech coding, visual representation of speech, and the possibility of improved automatic speech recognition to name but a few. It is unsurprising, therefore, that researchers have been investigating the acoustic-to-articulatory inversion mapping for several decades now. A great variety of approaches and models have been applied to the problem. Unfortunately, the overwhelming majority of these attempts have faced difficulties in satisfactorily assessing performance in terms of genuine human articulation. However, technologies such as electromagnetic articulography (EMA) mean that measurement of human articulation during speech has become increasingly accessible. Crucially, a large corpus of acoustic-articulatory data during phonetically-diverse, continuous speech has recently been recorded at Queen Margaret College, Edinburgh. One of the primary motivations of this thesis is to exploit the availability of this remarkable resource. Among the data-driven models which have been employed in previous studies, the feedforward multilayer perceptron (MLP) in particular has been used several times with promising results. Researchers have cited advantages in terms of memory requirement and execution speed as a significant factor motivating their use. Furthermore, the MLP is well known as a universal function approximator; an MLP of suitable form can in theory represent any arbitrary mapping function. Therefore, using an MLP in conjunction with the relatively large quantities of acoustic-articulatory data arguably represents a promising and useful first research step for the current thesis, and a significant part of this thesis is occupied with doing this. Having demonstrated an MLP which performs well enough to provide a reasonable baseline, we go on to critically evaluate the suitability of the MLP for the inversion mapping. The aim is to find ways to improve modelling accuracy further. Considering what model of the target articulatory domain is provided in the MLP is key in this respect. It has been shown that the outputs of an MLP trained with the sum-of-squares error function approximate the mean of the target data points conditioned on the input vector. In many situations, this is an appropriate and sufficient solution. In other cases, however, this conditional mean is an inconveniently limiting model of data in the target domain, particularly for ill-posed problems where the mapping may be multi-valued. Substantial evidence exists which shows that multiple articulatory configurations are able to produce the same acoustic signal. This means that a system intended to map from a point in acoustic space can be faced with multiple candidate articulatory configurations. Therefore, despite the impressive ability of the MLP to model mapping functions, it may prove inadequate in certain respects for performing the acoustic-to-articulatory inversion mapping. Mixture density networks (MDN) provide a principled method to model arbitrary probability density functions over the target domain, conditioned on the input vector. In theory, therefore, the MDN offers a superior model of the target domain compared to the MLP. We hypothesise that this advantage will prove beneficial in the case of the acoustic-to-articulatory inversion mapping. Accordingly, this thesis aims to test this hypothesis and directly compare the performance of MDN with MLP on exactly the same acoustic-to-articulatory inversion task.},

Our conventional recognition system based on substroke HMMs (hidden Markov models) employs straight-type substrokes as primary models and has achieved high recognition rate in the recognition of careful Kanji handwritings. On the other hand, the recognition rate for cursive handwritings is comparatively low, since they consist of mainlycurve-strokes. Therefore, we propose a technique of using multiple models for each substroke by considering the substroke context, which is a preceding substroke and a following substroke. In order to construct these context-dependent models efficiently, we use the SSS (Successive State Splitting) algorithm developed in speech recognition. Through the experiments, the recognition rate improved from 88\% to 92\% for cursive Kanji handwritings and from 90\% to 98\% for Hiragana handwritings.},

However, the quality of the strategy learned by the system depends on the definition of the optimization criterion and on the accuracy of the environment model.

  title = {Using Prosody in {ASR}: the Segmentation of Broadcast Radio News},
  abstract = {This study explores how prosodic information can be used in Automatic Speech Recognition (ASR). A system was built which automatically identifies topic boundaries in a corpus of broadcast radio news. We evaluate the effectiveness of different types of features, including textual, durational, F0, Tilt and ToBI features in that system. These features were suggested by a review of the literature on how topic structure is indicated by humans and recognised by both humans and machines from both a linguistic and natural language processing standpoint. In particular, we investigate whether acoustic cues to prosodgz?{g information can be used directly to indicate topic structure, or whether it is better to derive discourse structure from intonational events, such as ToBI events, in a manner suggested by Steedman's (2000) theory, among others. It was found that the global properties of an utterance (mean and maximum F0) and textual features (based on Hearst's (1997) lexical scores and cue phrases) were effective in recognising topic boundaries on their own whereas all other features investigated were not. Performance using Tilt and ToBI features was disappointing, although this could have been because of inaccuracies in estimating az?{g}these~0g}7{ parameters. We suggest that different acoustic cues to prosody are more effective in recognising discourse information at certain levels of discourse structure than others. The identification of higher level structure is informed by the properties of lower level structure. Although the findings of this study were not conclusive on this issue, we propose that prosody in ASR and synthesis should be represented in terms of the intonational events relevant to each level of discourse structure. Further, at the level of topic structure, a taxonomy of events is needed to describe the global F0 properties of each utterance that makes up that structure.}},

The HMM has known weaknesses, such as the strong ``independence assumption'' which presumes observations to be uncorrelated. New types of statistical modelling are now being investigated to overcome the weaknesses of HMMs. One such model is the Linear Dynamical Model (LDM), whose properties are more appropriate to speech. Modelling phone segments with LDMs gives fairly good classification and recognition scores, and this report explores possible extensions to a system using such models. Training only one model per phone cannot fully model variation that exists in speech, and perhaps training more than one model for some segments will improve accuracy scores. This is investigated here, and four methods for building two models instead of one for any phone are presented. Three of the methods produce significantly increased classification accuracy scores, compared to a set of single models.},
