Speaker Diarization And Identification From Single-Channel Classroom Audio Recording Using Virtual Microphones, Antonio Gomez

Electrical and Computer Engineering ETDs

Speaker identification in noisy audio recordings, specifically those from collaborative learning environments, can be extremely challenging. There is a need to identify individual students talking in small groups from other students talking at the same time. To solve the problem, we assume the use of a single microphone per student group without any access to previous large datasets for training.

This dissertation proposes a method of speaker identification using cross-correlation patterns associated to an array of virtual microphones, centered around the physical microphone. The virtual microphones are simulated by using approximate speaker geometry observed from a video recording. The patterns …

The Relationship Between Optional Developmental Education Enrollment And The Mathematics Achievement Of Students At One Community College In Florida, Andrea Lisa Lee

Educational Leadership & Workforce Development Theses & Dissertations

Although nearly half of community college students require some type of remediation, less than one-third of the students who start in developmental education graduate within eight years (Park, Tandberg, Hu, & Hankerson, 2016). As such, there is great uncertainty regarding the effectiveness of developmental education (Ari et al., 2016; Bailey et al., 2013). Additionally, because most institutions rely on standardized testing to determine student course placements, many critics blame placement testing procedures for the perceived ineffectiveness of developmental education (Fletcher, 2014; Jaggars & Hodara, 2013). However, rather than adjust placement procedures, some states moved away from mandated placement, and in …
