ANALOR. A Tool for Semi-Automatic Annotation of French Prosodic Structure

International audienceIn the area of large speech corpora, there is a definite need for common prosodic notation system based on efficient (semi)- automating tools of prosodic segmentation and labelling. In this context, we present the software program ANALOR, developed in order to process semi-automatically prosodic data. From a text-sound alignment, this computer tool detects major prosodic units, on the basis of global and local melodic variations. That leads to the segmentation of an utterance in prosodic periods. Inside those prosodic periods, prominent syllables are then automatically detected

Rhapsodie: a Prosodic-Syntactic Treebank for Spoken French

International audienceThe main objective of the Rhapsodie project (ANR Rhapsodie 07 Corp-030-01) was to define rich, explicit, and reproducible schemes for the annotation of prosody and syntax in different genres (± spontaneous, ± planned, face-to-face interviews vs. broadcast, etc.), in order to study the prosody/syntax/discourse interface in spoken French, and their roles in the segmentation of speech into discourse units (Lacheret, Kahane, & Pietrandrea forthcoming). We here describe the deliverable, a syntactic and prosodic treebank of spoken French, composed of 57 short samples of spoken French (5 minutes long on average, amounting to 3 hours of speech and 33000 words), orthographically and phonetically transcribed. The transcriptions and the annotations are all aligned on the speech signal: phonemes, syllables, words, speakers, overlaps. This resource is freely available at www.projet-rhapsodie.fr. The sound samples (wav/mp3), the acoustic analysis (original F0 curve manually corrected and automatic stylized F0, pitch format), the orthographic transcriptions (txt), the microsyntactic annotations (tabular format), the macrosyntactic annotations (txt, tabular format), the prosodic annotations (xml, textgrid, tabular format), and the metadata (xml and html) can be freely downloaded under the terms of the Creative Commons licence Attribution - Noncommercial - Share Alike 3.0 France. The metadata are encoded in the IMDI-CMFI format and can be parsed on line

Design and Evaluation of Shared Prosodic Annotation for Spontaneous French Speech: From Expert Knowledge to Non-Expert Annotation

International audienceIn the area of large French speech corpora, there is a demonstrated need for a common prosodic notation system allowing for easy data exchange, comparison, and automatic annotation. The major questions are: (1) how to develop a single simple scheme of prosodic transcription which could form the basis of guidelines for non-expert manual annotation (NEMA), used for linguistic teaching and research; (2) based on this NEMA, how to establish reference prosodic corpora (RPC) for different discourse genres (Cresti and Moneglia, 2005); (3) how to use the RPC to develop corpus-based learning methods for automatic prosodic labelling in spontaneous speech (Buhman et al., 2002; Tamburini and Caini 2005, Avanzi, et al. 2010). This paper presents two pilot experiments conducted with a consortium of 15 French experts in prosody in order to provide a prosodic transcription framework (transcription methodology and transcription reliability measures) and to establish reference prosodic corpora in French

Prosodic Phrasing in Spontaneous Swedish

One of the most important functions of prosody is to divide the flow of speech into chunks. The chunking, or prosodic phrasing, of speech plays an important role in both the production and perception of speech. This study represents a move away from the laboratory speech examined in previous, related studies on prosodic phrasing in Swedish, since a spontaneous, Southern Swedish speech material is investigated. The study is, however, not primarily intended as a study of the Southern Swedish dialect; rather Southern Swedish is used as a convenient object on which to test various hypotheses about the phrasing function of prosody in spontaneous speech. The study comprises both analyses of production data and perception experiments, and both the phonetics and phonology of prosodic phrasing is dealt with. First, the distribution of prosodic phrase boundaries in spontaneous speech is examined by considering it as a reflection of optimality theoretic constraints that restrain the production and perception of speech. Secondly, the phonetic realization of prosodic phrase boundaries is investigated in a study on articulation rate changes within the prosodic phrase. Evidence of phrase-final lengthening, a reduction of the articulation rate in the final part of the prosodic phrase, is found. The tonal means used to signal coherence within the prosodic phrase is subsequently investigated. An attempt is made to test the two Lund intonation models’ capacities for describing spontaneous speech. The two approaches have different implications for the amount of preplanning needed, which makes them particularly interesting to compare by testing spontaneous data. The results indicate that no or little preplanning is needed to produce tonally coherent phrases. No evidence is found to suggest e.g. that speakers accommodate for the length of the upcoming phrase by starting longer phrases with a higher F0 than short phrases. An explanation is sought for variation in F0 starting points found in the data despite F0’s insensitivity to phrase length. It is concluded that F0 is used to signal coherence even across prosodic phrase boundaries. It is furthermore found that tonal coherence signals are used to override strong boundary signals in spontaneous speech, thereby making initially unplanned additions possible. Finally, the perception of boundary strength is examined in two perception experiments. Listeners are found to agree well in their perceptual judgments of boundary strength, and it is shown that the main correlate to perceived boundary strength in spontaneous speech is pause length. The useful distinction between weak, prosodic phrase boundaries and strong, prosodic utterance boundaries in descriptions of read speech is found to be inappropriate for descriptions of spontaneous speech. It fails to capture the conflicting local and global signals of boundary strength and coherence that arise when strong boundary signals are overriden by coherence signals. The possibility to use conflicting signals in this way is seen as an important asset to the speaker as it makes changes in the speech plan possible, and it is regarded to be a characteristic of prosodic phrasing in spontaneous speech

The illocution-prosody relationship and the Information Pattern in spontaneous speech according to the Language into Act Theory (L-AcT)

This paper introduces the question of the definition of reference units for speech, correlating with the necessary condition that they must be an adequate and useful means for analyzing large spoken corpora. According to Language into Act Theory (L-AcT), the utterance is the proper reference unit and the counterpart of the speech act (Austin 1962), being demarcated by prosody within the flow of speech. The pragmatic foundations of the utterance and its information structure will be described and are closely connected to the role of prosody in their identification. The pragmatic and information analysis of English and Romance examples are presented, which are taken from representative spoken corpora (C-ORAL-ROM, C-ORAL-BRAZIL, S. Barbara Corpus). Regarding the information structure, the Comment unit is considered the core of the Information Pattern and since its role is the expression of the illocution it automatically conveys the new information. The Comment may be accompanied and supported by other optional information units which are functionally differentiated. The Information Pattern is systematically demarcated by a Prosodic Pattern within an isomorphic correlation

Prosodic boundary phenomena

Synopsis: In spoken language comprehension, the hearer is faced with a more or less continuous stream of auditory information. Prosodic cues, such as pitch movement, pre-boundary lengthening, and pauses, incrementally help to organize the incoming stream of information into prosodic phrases, which often coincide with syntactic units. Prosody is hence central to spoken language comprehension and some models assume that the speaker produces prosody in a consistent and hierarchical fashion. While there is manifold empirical evidence that prosodic boundary cues are reliably and robustly produced and effectively guide spoken sentence comprehension across different populations and languages, the underlying mechanisms and the nature of the prosody-syntax interface still have not been identified sufficiently. This is also reflected in the fact that most models on sentence processing completely lack prosodic information. This edited book volume is grounded in a workshop that was held in 2021 at the annual conference of the Deutsche Gesellschaft für Sprachwissenschaft (DGfS). The five chapters cover selected topics on the production and comprehension of prosodic cues in various populations and languages, all focusing in particular on processing of prosody at structurally relevant prosodic boundaries. Specifically, the book comprises cross-linguistic evidence as well as evidence from non-native listeners, infants, adults, and elderly speakers, highlighting the important role of prosody in both language production and comprehension

Methods in prosody

This book presents a collection of pioneering papers reflecting current methods in prosody research with a focus on Romance languages. The rapid expansion of the field of prosody research in the last decades has given rise to a proliferation of methods that has left little room for the critical assessment of these methods. The aim of this volume is to bridge this gap by embracing original contributions, in which experts in the field assess, reflect, and discuss different methods of data gathering and analysis. The book might thus be of interest to scholars and established researchers as well as to students and young academics who wish to explore the topic of prosody, an expanding and promising area of study
