This paper describes the STCON system for the CHiME-7 challenge Task 1 (DASR) aimed at distant automatic speech transcription and segmentation with multiple recording devices. The system is generally similar to the Speech Technology Center (STC) system for the CHiME-6 challenge but uses more sophisticated and advanced models for diarization and ASR. Care-fully designed pipeline provides significant improvements com-pared to the baseline system.
