ASR Captioning

The use of automatic speech recognition (ASR) technology to generate real-time text captions of spoken language, commonly used as an accessibility tool for Deaf and Hard of Hearing individuals in meetings, lectures, and video calls. Unlike professional captioning services (such as CART), ASR captioning is available instantly and at no additional cost through platforms like Google Meet, Zoom, and Microsoft Teams. However, ASR captioning is prone to errors, particularly with accented speech, fast speaking rates, background noise, and technical terminology. The accuracy of ASR captions is directly influenced by how clearly and at what pace the speaker talks, making speaker behavior modification a complementary strategy for improving caption quality.
