TALK TITLE:  “Challenges and Advancements in Speaker Diarization & Recognition for Naturalistic Data Streams”


John H. L. HansenSpeech communications represents a core domain for education, team problem solving, social engagement, and business interactions. The ability for Speech Technology to extract layers of knowledge and assess engagement content represents the next generation of advanced speech solutions.

Today, the emergence of BIG DATA, Machine Learning, as well as voice-enabled speech systems have required the need for effective voice capture and automatic speech/speaker recognition. The ability to employ speech and language technology to assess human-to-human interactions offers new research paradigms having profound impact on assessing human interaction.

In this talk, Dr. Hansen will focus on big data naturalistic audio processing relating to (i) child learning spaces, and (ii) the NASA APOLLO lunar missions. ML based technology advancements include automatic audio diarization, speech recognition, and speaker recognition. Child-Teacher based assessment of conversational interactions are explored, including keyword and “WH-word” (e.g., who, what, etc.). Diarization processing solutions are applied to both classroom/learning space child speech, as well as massive APOLLO data.

CRSS-UTDallas is expanding their original Apollo-11 corpus, resulting in a massive multi-track audio processing challenge to make available 150,000 hours of Apollo mission data to be shared with science communities: (i) speech/language technology, (ii) STEM/science and team-based researchers, and (iii) education/historical/archiving specialists. The goals here are to provide resources that allow a better understanding of how people work/learn collaboratively; and for Apollo, to accomplish one of mankind’s greatest scientific/technological challenges in the last century.
