The paper presents a new corpus of dialogue speech designed specifically for research in the field of speech entrainment. Given that the degree of accommodation may depend on a number of social factors, the corpus is designed to encompass 5 types of relations between the interlocutors: those between siblings, close friends, strangers of the same gender, strangers of the other gender, strangers of which one has a higher job position and greater age. Another critical decision taken in this corpus is that in all these social settings one speaker is kept the same. This allows us to trace the changes in his/her speech depending on the interlocutor. The basic set of speakers consists of 10 pairs of same-gender siblings (including 4 pairs of identical twins) aged 23-40, and each of them was recorded in the 5 settings mentioned above. In total we obtained 90 dialogues of 25-60 minutes each. The speakers played a card game and a map game; they were recorded in a soundproof studio without being able to see each other due to a non-transparent screen between them. The corpus contains orthographic, phonetic and prosodic annotation and is segmented into turns and inter-pausal units.

The paper introduces CORPRES ― a fully annotated Russian speech corpus developed at the Department of Phonetics, St. Petersburg State University as a result of a three-year project. 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 for this part was generated and stored as text files. The fully annotated part of the corpus covers all speaking styles included in the corpus and all speakers. The paper contains information about CORPRES design and annotation principles, overall data description and some speculation about possible use of the corpus.
