Balalaika pipeline enhances Russian speech data with prosody-aware annotations

Researchers have developed Balalaika, an open-source pipeline designed for annotating Russian speech data with a focus on prosody. This system integrates semantic voice activity detection, multi-ASR ensembling, and automatic quality filtering to create a 5.1k-hour corpus. The pipeline also enriches the text with punctuation, lexical stress, and phoneme normalization, demonstrating consistent improvements in speech denoising and text-to-speech synthesis. AI
