The corpus includes samples of different speaking styles produced by 4 male and 4 female speakers. Six levels of annotation cover all phonetic and prosodic information about the recorded speech data, including labels for pitch marks, phonetic events, narrow and wide phonetic transcription, orthographic and prosodic transcription. Precise phonetic transcription of the data provides an especially valuable resource for both research and development purposes. Overall corpus size is 528 458 running words and contains 60 hours of speech made up of 7.5 hours from each speaker. 40 % of the corpus was manually segmented and fully annotated on all six levels. 60 % of the corpus was partly annotated; there are labels for pitch period and phonetic event labels. Orthographic, prosodic and ideal phonetic transcription...

The children's speech presents a reliable material for analysing emotions as children's emotional expression is spontaneous and their verbal behaviour is least determined by social conventions. Two parallel corpora containing the expressions of an identical set of emotions (FAU AIBO Emotion Corpus and Corpus of Russian Children's Emotional Speech) were used. The emotions were elicited in very similar conditions. The data from four types of cross-language experiments were obtained: Germans evaluating German speech, Germans evaluating Russian speech, Russians evaluating Russian speech, Russians evaluating German speech. The confusion matrices of emotion recognition in all types of experiments were compared. The universal and language specific patterns of perceiving emotions were detected ...

Three experiments were carried out to investigate differences and similarities in the assessment of emotions by German and Russian adult listeners. The corpora of German and Russian emotional children's speech were employed in the first and second experiments. In the third experiment German and Russian 'delexicalised' utterances were used. They were selected from the both corpora and added white noise to. Thus the semantic content was removed while the prosodic features stayed intact. The experiment was aimed at analyzing recognition strategies when listeners rely only on prosody while segmental level information is not present. The experiments revealed similar and different patterns of assessing emotions in children's speech in German and Russian. The study contributes to better understanding of cross-lingual human emotion perception and the role of verbal, seg...

This can be observed when one of the following vowels is rounded. The aim of current research is to define how strong this phonological process is and what factors trigger the process. The experimental results showed this tendency in speech of young adults. Vowel labialization occurs in about a third of non-immediately-pretonic and post-tonic syllables in connected speech. While the roundedness of vowels does not affect word intelligibility, it is clearly perceived when vowels are perceived in isolation or within a syllable. The tendency should be taken into account in developing probabilistic dictionaries for automatic speech recognition and G2P procedures.

The construction of this type of corpora will allow finding common patterns of acoustic manifestation of similar functional states regardless of the language. The analysis of these corpora will also allow investigating universal and language-specific features reflected in speech. Two pilot experiments which may contribute to the proposed strategy are presented.

The new method of recording the glottal wave synchronously with an output speech signal was employed to obtain the experimental material. The comparison of the recorded signals allowed analyzing the structure of the speech signal at different stages of its generation. As a result, the classic vocal tract model was specified by distinguishing a feedback component which formalizes the processes in the vocal tract as a complex acoustic nonlinear system. One of the functions of the component is to transform the acoustic energy from the articulation system upstream. In the paper the recording method is described, perceptual experiment and the acoustic analysis results are presented.

The study employs the method of electromagnetic articulography (EMA) to observe and compare objective data on articulatory characteristics in singing and reading. The genre of romance was chosen as it does not normally employ vocal techniques specific to opera singing (vibrato and etc.) which affect vowel intelligibility significantly. The romance chosen for the experiment is often performed by Russian singers being a part of canonic repertoire at conservatoires. We obtained the samples of singing and read speech and registered the objective data in both types of articulation activities. The recordings can be considered parallel as they were made in succession during one experiment. The calibration and attachment of the sensors was performed once in the beginning of the experiment. That means that the sensor positions...
