On the strongly regular graphs obtained from quasi-symmetric 2-(31,7,7) designs
It is known that the five non-isomorphic quasi-symmetric 2-(31, 7, 7) designs lead to non-isomorphic strongly regular graphs with parameters (155, 42, 17, 9). We will show that there exist no isomorphisms among these graphs and the block graphs of the Steiner triple systems STS(31) except the isomorphism between the block graphs of the point-plane design and the point-line design of PG(4, 2)
CHiME-6 Challenge:Tackling Multispeaker Speech Recognition for Unsegmented Recordings
Following the success of the 1st, 2nd, 3rd, 4th and 5th CHiME challenges we
organize the 6th CHiME Speech Separation and Recognition Challenge (CHiME-6).
The new challenge revisits the previous CHiME-5 challenge and further considers
the problem of distant multi-microphone conversational speech diarization and
recognition in everyday home environments. Speech material is the same as the
previous CHiME-5 recordings except for accurate array synchronization. The
material was elicited using a dinner party scenario with efforts taken to
capture data that is representative of natural conversational speech. This
paper provides a baseline description of the CHiME-6 challenge for both
segmented multispeaker speech recognition (Track 1) and unsegmented
multispeaker speech recognition (Track 2). Of note, Track 2 is the first
challenge activity in the community to tackle an unsegmented multispeaker
speech recognition scenario with a complete set of reproducible open source
baselines providing speech enhancement, speaker diarization, and speech
recognition modules
