The method includes: carrying out an enrollment session offline to enroll a speaker model in a speech processing system using JFA, including: extracting speaker factors from the enrollment session; estimating first components of channel factors from the enrollment session. The method further includes: carrying out a test session including: calculating second components of channel factors strongly dependent on the test session; and generating a score based on speaker factors, channel factors, and test session Gaussian mixture model sufficient statistics to provide a log-likelihood ratio for a test session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Joint factor analysis scoring for speech processing systems","description":"Method, system, and computer program product are provided for Joint Factor Analysis (JFA) scoring in speech processing systems.
