CART

A real-time captioning service in which a trained stenographer uses a specialized keyboard to transcribe spoken language into text as it is spoken, typically achieving accuracy rates above 98%. CART is considered the gold standard for real-time captioning accuracy but is expensive ($120-200 per hour), making it impractical for routine daily meetings. It is widely used for European languages but less common for languages with large character sets such as Japanese and Chinese, where the complexity of character input creates additional challenges.
