Closed captioning is an essential feature that helps people who are deaf or hard-of-hearing to follow along with video content, and it's increasingly being used by others as well. Speech-to-text technology and automatic speech recognition (ASR) play a crucial role in enabling closed captioning for various types of media, including live events, television broadcasts, educational videos, podcasts, and more. By using AI-powered solutions like Deepgram, companies can provide accurate and real-time captions that improve accessibility and user experience across different domains.
