Does WCAG Level AAA require sign language?
Yes. WCAG Success Criterion 1.2.6 explicitly requires sign language interpretation for all prerecorded audio content in synchronized media to achieve Level AAA conformance.
How does Acceasy compare to automated CSS widgets?
Automated widgets only modify CSS fonts and colors. They provide zero sign language capability. Acceasy provides synchronized National Sign Language translation layers created by human sign language linguists.
Which legal frameworks are supported?
Acceasy supports accessibility compliance under ADA Title III and Section 508 (United States, via ASL in partnership with Visual Voice Media), Ley 982/1618 (Colombia), and Lei Brasileira de Inclusão (Brazil).
