Dialogs: A Studio-Quality Russian Conversational Speech Corpus for Dialog Assistants

Researchers present Dialogs, a 20.6-hour Russian conversational speech corpus recorded in a professional studio, featuring 3 speakers and 11,796 utterances. The dataset is notable for capturing turn-taking rhythm and expressive prosody, with per-utterance style and emotion labels across 12 categories. Crowd MOS tests indicate that Dialogs achieves higher ratings for expressiveness and conversational naturalness compared to existing studio baselines. A VITS2 model trained on Dialogs demonstrates the corpus's potential for expressive, dialog-like text-to-speech synthesis.

Why it matters: Dialogs provides a high-quality resource for developing more natural and expressive Russian dialog assistants, addressing a gap in available conversational speech data.
