On August 24, UK-based Talksign launched what it calls the first two-sided marketplace for sign language datasets, paying signers $10 to $30 per hour to contribute annotated video while selling the resulting collections to AI researchers. The catalog went live with seven datasets spanning more than 700 hours of verified, annotated sign-language content across seven languages, according to a company statement shared with Technext24.
The move addresses what remains a stubborn infrastructure problem in artificial intelligence development. Sign-language datasets are scarce and fragmented compared to the sprawling text and speech corpora that power mainstream language models. A 2022 NeurIPS Datasets & Benchmarks paper documented this gap, which continues to be cited by researchers, a testament to how little has changed. Talksign's marketplace offers researchers something that has been elusive: production-ready data with explicit consent and source verification attached. For Deaf signers, it creates paid remote work in an economy that has historically shut them out.
The platform lists datasets by language, domain, and format. Initial offerings include a 240-hour ASL Conversational Corpus with 12,400 clips, an 85-hour BSL Healthcare Dialogues collection spanning 4,200 clips, and a 120-hour ISL Education Vocabulary set containing 8,900 clips, according to a catalog crawled between August 27 and 29. Additional datasets cover Auslan, French Sign Language, and German Sign Language.
Buyers license the data for model training, evaluation, and avatar synthesis. Contributors work remotely as interpreters, data collectors, annotators, and quality reviewers. The site lists roles with specific pay bands: ASL Interpreter at $18 to $26 per hour, BSL Interpreter at $16 to $24 per hour, and Quality Reviewer at $20 to $30 per hour. Counters on the platform show more than 300 roles created and $100,000 paid out—vendor-reported figures that have not been independently verified.
Verification as a selling point
"Every dataset listed on the Marketplace can be checked through our verification portal at verify.talksign.co," founder and CEO Edidiong Ekong wrote on LinkedIn around August 27. "It's open, so a buyer, a contributor, or an outside researcher can confirm what a dataset actually is before anyone builds on it."
The Condia reported August 25 that the verification portal ties each dataset to its source and consent terms. Talksign's legal documents, updated in June and effective July 1, distinguish between live conversation data—which the company says is processed transiently on-device and never stored or used for training—and marketplace contributions explicitly acquired for model development under a contributor agreement. That distinction matters in a regulatory environment increasingly focused on data provenance and consent.
The marketplace is one part of a broader product suite. Talksign, incorporated in England and Wales as Company No. 17060416, develops real-time speech-to-sign translation infrastructure. The company launched Talksign-1, a bidirectional ASL translation model, in February, claiming sub-100-millisecond latency and a 250-sign vocabulary, TechCabal reported February 16. Ekong brought on Kazi Mahathir Rahman as CTO in December, according to a LinkedIn post from mid-February.
Other products include Talksign OS, a cross-device real-time translation platform, and Talksign XR, smart glasses with sign-to-speech capabilities, according to the company's website as of late August.
A growing field, still fragmented
The marketplace arrives months after NYU Abu Dhabi spun out ChatSign, a real-time speech-to-sign system for Arabic, English, Emirati Sign Language, and ASL, the university announced May 18. UK-based Signapse offers a commercial API called SignStream on AWS Marketplace. Signly lists a "Sign Language as a Service" product on the Microsoft commercial marketplace. NVIDIA runs a Trustworthy AI program collecting ASL data, and AWS Open Data hosts an ASL dataset. The activity suggests growing institutional interest, though the field remains fragmented and underfunded relative to other AI domains.
"Today we're launching the Talksign Marketplace, a place where Deaf communities, researchers, institutions, and companies can contribute, annotate, license, and access high-quality sign language datasets," Ekong said in the company's August 24 statement. The marketplace page displayed an average pay rate of $10 per hour when crawled in late August, with role-specific rates ranging up to $30 per hour for quality review work.
Whether the marketplace gains traction will depend on factors beyond technology: whether researchers can afford the datasets, whether contributors find the pay competitive, and whether the verification structure proves robust enough to satisfy both sides. For now, Talksign has created infrastructure where little existed before.
