SAAC introduces a novel front-end for DHH learners, featuring speaker-attributed captions, confidence-gated affect tags, and on-demand AI summaries. This addresses the limitations of traditional live captioning in multi-speaker STEM environments by enhancing clarity and reducing cognitive load.
The system is designed with cognitive support in mind, translating complex backend AI (diarization, emotion recognition, language modeling) into an intuitive user experience. Principles of calibrated trust and conversation analysis guide the display of information.
A within-subject pilot study (n=16) demonstrated that SAAC significantly improved comprehension and was preferred over baseline. AI Describe served as a valuable recovery scaffold, and emotion tags provided an optional 'gist' layer, enhancing overall understanding without increasing workload.
5.0/5.0
Median Comprehension Score (SAAC)
Participants achieved a median score of 5.0 out of 5.0 in comprehension quizzes with SAAC, significantly outperforming the baseline system.
Addressing the 'Gaze-Switching Dilemma'
Traditional captions often force DHH learners to choose between tracking interactional cues and processing text. SAAC mitigates this by integrating speaker attribution, vocal-affect cues, and AI summaries directly into the caption view, reducing inferential burden and split attention.

User Preference and Trust Calibration
“Participants overwhelmingly preferred SAAC, citing its ability to clarify meaning and serve as a recovery mechanism. They calibrated their trust, using AI Describe as a reliable aid and emotion tags as a 'gist' layer rather than absolute truths, especially in academic contexts.”

Implementation Roadmap
Our phased implementation plan ensures a smooth transition and maximum impact for your organization.
Phase 1: Discovery & Customization
We begin with an in-depth analysis of your existing communication infrastructure and classroom needs. This phase involves stakeholder interviews, technical assessments, and defining key performance indicators (KPIs) to tailor SAAC to your specific environment. Expected duration: 2-4 weeks.
Phase 2: Pilot Deployment & User Training
A pilot version of SAAC is deployed in selected classrooms or meeting environments. We conduct comprehensive training sessions for instructors and DHH learners, gathering initial feedback for refinement. This phase focuses on ensuring a seamless user experience and addressing any immediate integration challenges. Expected duration: 4-6 weeks.
Phase 3: Full Integration & Optimization
Based on pilot feedback, SAAC is fully integrated across your desired platforms. Ongoing monitoring and optimization ensure peak performance and continuous improvement. We also provide advanced analytics and support to maximize the long-term benefits of the system. Expected duration: 6-8 weeks.
