In testing, the corporate stated the mannequin achieved 84.7% accuracy on single indicators. Nonetheless, the corporate acknowledges that the system doesn’t but assist steady sentence-level interpretation or fingerspelling, which limits its use to remoted indicators slightly than full conversations.
