BSpeak: An Accessible Voice-based Crowdsourcing Marketplace for Low-Income Blind People

BSpeak is an accessible crowdsourcing marketplace that enables blind people in developing regions to earn money by transcribing audio files through speech. We examine accessibility and usability barriers that 15 first-time users, who are low-income and blind, experienced while completing transcription tasks on BSpeak and Mechanical Turk (MTurk). Our mixed-methods analysis revealed severe accessibility barriers in MTurk due to the absence of landmarks, unlabeled UI elements, and improper use of HTML headings. Compared to MTurk, participants found BSpeak significantly more accessible and usable, and completed tasks with higher accuracy in lesser time due to its voice-based implementation. In a two-week field deployment of BSpeak in India, 24 low-income blind users earned rupee 7,310 by completing over 16,000 transcription tasks to yield transcriptions with 87% accuracy. Through our analysis of BSpeak's strengths and weaknesses, we provide recommendations for designing crowdsourcing marketplaces for low-income blind people in resource-constrained settings.
