Sie ersuchen eine Bestätigung von schon bekannter Information und werden deshalb auch Bestätigungsfragen genannt. In der traditionellen Literatur über die bulgarische Intonationsphonologie ist die Beschreibung dieser Fragen extrem widersprüchlich. Ziel der vorliegenden Arbeit ist es, im Rahmen eines Perzeptionsexperiments Evidenz dafür zu finden, welche akustischen Parameter eine Äußerung als Frage kennzeichnen, wenn sie nicht syntaktisch bzw. lexikalisch markiert ist, d.h. welche die distinktive Intonationskontur ist, die bei Fragen und Aussagen mit gleicher segmentaler und syntaktischer Struktur die Satzmoduszuweisung steuert.},

      ABSTRACT = {An earlier study [1] illuminated the role of F0 contours on the focus accent in differentiating question and sentence mode in the Sofia variety of Bulgarian.The results showed that placement of the low target of the pitch accent at the beginning and the peak at the end of the accented syllable or in the following syllable (L*+H) is critical for the perception of (syntactically and lexically unmarked) checks, which are used to confirm already known information [2]. By shifting the peak leftwards towards the beginning of the accented syllable (H*) the pragmatic category changed from check to statement. Both categories have a L% boundary tone. However, subjects' judgements indicated that the strength of the intonational information was not equal for the two utterance types. The situational pre-context had a strong influence on the interpretation of the utterance as a check or statement. In case the intonation contour diverged from the unmarked contour for a particular function, the category judgement was accompanied by a change in the emotional message. To examine the general validity of these observations a further experiment was carried out. Three checks, three statements with low terminal boundary tones (L%), and three statements with continuation rises (H%) were selected from Map Task recordings made for a number of male and female speakers [3]. From each of these 9 natural utterances three intonational variants were generated, one for each pragmatic category. Firstly, a stylised resynthesized version of the original (e.g. a check) was produced. Then the intonation contours for the other two pragmatic categories (e.g. statement with terminal fall and continuation rise) were derived from the stylised contour. Four repetitions of the stimuli were presented (Roman square design) to 15 native speakers of Sofia Bulgarian in three situational contexts: question, neutral statement and polite statement. The context utterance together with the stimulus form a minimal dialogue. The natural context for the check was a statement, and for the two statement forms it was a question. In the test, each context was offered with each pragmatic category, producing potential tension between context and stimulus. The subjects were required to judge - on a five-point scale - the degree to which each stimulus was suited to its context. The results show that all three intonational contours can be accepted as statements in the context of a preceding question, whereas the change of context cannot shift the interpretation of a statement to a check. The following explanation can be offered for this asymmetry of reinterpretation. The context plays an extremely important role for the interpretation of checks or statements. The context priming a statement (question-answer sequence) provides enough information to uniquely specify the communicative frame. It is a strong enough speech act marker to relegate function of the intonational form to a minor one. Thus the context weakens the distinctive function that intonation has when word sequence and syntactic structure are identical.This does not, however, mean that the intonational form is irrelevant. The shift in the interpretation of the sentence mode (check to statement) can only occur because a compensatory change of modal meaning accompanies it. The check contour cannot be accepted as a neutral statement, it can only be accepted as an emphatic, impatient or angry statement. The statements with a continuation rise were also accepted in the statement context, but the compensatory modal message was of an exaggeratedly polite speaker. Apparently, when a typical (neutral) feature of a particular communicative situation is replaced by a feature typical of another situation, it introduces an additional modal marking. Thus intonation alone, without syntactic and lexical support, can imply a certain shade of modal meaning. This phenomenon is already known at the grammatical level. In Bulgarian, for example, the future tense is the neutral form for referring to events in the future. If the present tense is used, the utterance is immediately modally marked as a firm intention. In English and German the reverse is true.}

      ABSTRACT = {Ten MAP Task dialogues for Sofia Bulgarian (SB) and six for Hamburg German (HG) are recorded and analyzed by means of X-Waves Software Package. The discourse intonation features focused on are denial and convergence. It has been observed that for German denial can be integrated into discourse-listing through intonation: Ja-acknowledge and Nein-/Ne-denial moves are both manifested by intonation rises. For Bulgarian, intonation rises in answering moves occur only in the acknowledge subtype: rises in denials (Ne-) are associated with uncertainty and surprise. The HG Ne- and SB Ne-moves are resynthesized by means of PSOLA, twelve stimuli being obtained for SB and sixteen for HG. Two appropriate contexts marked for discourse-listing and follow-up moves are excerpted from the MAP Task and are included in perceptual tests whereby native speakers are asked to determine the appropriateness of each stimulus in relation to each context. 'The results for Bulgarian contradict our preliminary observations. Convergence is defined as the matching of corresponding movements in pitch ranges and signals sympathetic agreement with the other speaker’s point of view. The check: answer move sequence can be viewed as instantiating convergence and exemplifies both lexical and Fo movement repetition, especially where ellipted moves are concerned. The two resynthesized sequences for HG and SB respectively are ”Im Westen” and ”Pravo nagore” as manifested in check and answering contexts. As above, native speakers are expected to determine the appropriateness of each stimulus in relation to each context. It has been observed that the differences between checks and answering moves for both HG and SB are phonetically manifested and are also established as being relevant by the perceptual tests, yet they cannot be accounted for phonologically by tone alignment: convergence seems to attenuate the phonological differentiation between checks and answering moves.},

      TITLE = {Phonetic features in ASR: A linguistic solution to acoustic variation?},
      YEAR = {2000},
      BOOKTITLE = {Proceedings of the 7th Conference on Laboratory Phonology (LabPhon7), June 29 -July 1},
      ADDRESS = {Nijmegen, Netherlands},
      ABSTRACT = {In most phonological theories, phonemes are considered as a set (or hierarchy) of (possibly underspecified) phonetic features, which are the minimal number of formal properties needed to distinguish the phonemes in the language system from each other. In most state-of-the-art automatic speech recognition (ASR) systems, however, phonetic features do not play any role. The statistical models for each phone or phoneme are based on a spectral parameterisation of the signals, like mel-frequency cepstral coefficients (MFCC's) and energy. Three questions are dealt with in this paper: Can we successfully bridge this gap between phonological theory and ASR by using phonetic features in ASR? Which phonetic feature set is most appropriate for ASR? Can we attain the same result by using more complex non-linguistic modelling? 1. PHONETIC FEATURES IN ASR To bridge the gap between phonologists' formal representation of the phoneme and the almost purely acoustic description of the signal used in ASR systems, we have used phonetic features to create statistical phone models for automatic speech recognition. The phonetic features were derived from the spectral representation of the signal used in most standard ASR systems (MFCC's + energy) by means of a neural network. Not only do we find a clear increase in the phoneme identification rate (see under 2 below) [1], the confusions between phonemes are also much easier to interpret, since phonemes which are confused are usually very similar in terms of the phonetic features they are made up of. This is not the case when acoustic parameters are used to create phoneme models [2]. 2. DIFFERENT PHONETIC FEATURE SETS It is not self-evident which set of phonetic features is most appropriate to describe phonological categories and the processes that operate on them, since the various feature theories have different phonological implications. To evaluate how appropriate the different feature sets are for application in an ASR system, we have used several different feature sets, both articulatory-phonetic (IPA) and phonological (SPE) [3]. We have so far compared the phoneme identification results for both underspecified and fully specified SPE features with those for the set of features used in the IPA to distinguish all phonemes. In addition, the results were compared to those in a standard ASR system using acoustic parameters (MFCC's) directly to create phone models. We found a clear improvement in the phoneme identification rate when phonetic features were used to model the phones, in comparison to directly using acoustic parameters. Underspecified SPE features led to the best performance (for multi-language Eurom0 data, without the use of a lexicon or language model) of all: acoustic parameters: 15.6% IPA features: 42.6% SPE features: 36.2% Underspecified SPE features: 46.1% In addition to the features sets reported so far, the phoneme identification results for articulatory features [4] will be reported and their relative merits will be discussed. 3. VARIATION MODELLING VERSUS LINGUISTIC MODELLING The acoustic-phonetic mapping in a neural network combines two advantages, namely 1) variation modelling: different acoustic realisations of the same phoneme (e.g. allophonic variants) can be discerned by the neural network 2) linguistic modelling: these different realisations are mapped onto more homogeneous, distinctive features Even if the neural network can reduce the variation in the input parameters for statistical modelling by mapping different acoustic realisations of a phoneme onto phonetic features, the question remains whether the same result can be reached by using a non-linguistic approach. Variation modelling can also be achieved by using more complex acoustic phoneme models (multiple mixtures per state in HMM), so that we do not necessarily have to make a mapping onto phonetic features to achieve this goal. A comparison of the performance of a standard system which does not use phonetic features with the performance of a system in which phonetic features are used to train the phoneme models shows the merits of using a signal representation derived from phonological theory.}

      ABSTRACT = {In this article we discuss implementation of some fundamental phonetic ideas related to what we shall call relational processing in a cross-language consonant identification system. The term relational processing refers to the way vowel transitions play a role in the identification of neighbouring consonants. Two experiments are described: first, consonant identification results from a hidden Markov modelling experiment are presented for consonants plus the preceding and following vowel transitions, if present. The results are compared to a baseline experiment, in which the vowel transitions are not used in the identification of the consonants. In the second experiment, the acoustic parameters are first mapped onto phonetic features; this mapping is performed by a Kohonen network1. Since vowel transitions are considered to be particularly important for identification of the place of articulation of the neighbouring consonant, only the place features (and not the consonants' manner features or the phonetic features of the vowel to which the transitions belong) are derived for the vowel transitions. Separate hidden Markov models are trained for the consonants, for the vowel offset and vowel onset transitions which share all consonantal place-of-articulation features. Concatenations of these models form the phone-like recognition units (comparable to the concatenation of phone models for the recognition of words in a conventional ASR system) which are later used for consonant identification. The results are compared with a baseline experiment in which no acoustic-phonetic mapping is performed. The experiments show that relational processing improves the consonant identification results.},

      ABSTRACT = {This article discusses the use of phonetic features in automatic speech recognition. The phonetic features are derived from acoustic parameters by means of Kohonen networks. Behind the use of phonetic features instead of standard acoustic parameters lies the assumption that it is useful to help the system to focus on linguistically relevant signal properties. Previous experiments using very simple hidden Markov models to represent the phones (with only one mixture for each state and without a lexicon or language model) have indeed shown that the phoneme identification rates on the basis of phonetic features were considerably higher than on the basis of acoustic parameters. When eight mixtures per state are used in hidden Markov modelling, the phoneme identification rates for three different sets of phonetic features were found to be lower than those obtained from a system in which the acoustic parameters are modelled directly. It is suggested that the results are still good enough, however, to further explore the use of phonetic features in a complete automatic speech recognition system: if each phone sequence representing a word in the lexicon is replaced by a sequence of underspecified phonetic feature vectors, the use of phonetic features in the acoustic decoding may have certain advantages.},

As a result, the phoneme identification rates in a hidden Markov modelling framework increase from 15.6% for the cepstral parameters to 42.3% and 31.7% for the IPA and SPE features, respectively. Furthermore, for phonetic features the resulting confusions between phonemes are often less severe from a phonetic point of view. The theoretical implications of the differences are addressed.},
