Real-time captioning converts speech into synchronized text for viewers.

Accuracy and readability depend on audio, latency, and the captioning method.
Automatic captions use speech recognition. Microsoft Speech, for example, documents intermediate Recognizing results that can change as more audio is processed and a final Recognized result after an utterance. Its real-time diarization workflow labels different speakers with identifiers such as Guest-1; these labels do not verify personal identity. CART instead uses a trained human captioner with stenotype, a computer and realtime software. Word error rate summarizes substitutions, deletions and insertions relative to a reference transcript, but does not capture all timing, readability or accessibility needs. W3C describes captions as synchronized text for speech and relevant non-speech audio and identifies WebVTT as a common web caption format. Meta’s Ray-Ban Display announcement describes captions for speech directed at the wearer; that is a specific device example.
Use streaming ASR to produce draft captions.
Use CART as a human stenographic captioning workflow.
Review speaker labels and revisions in a live event.
W3C identifies WebVTT as a common web caption format; Meta documents a device-specific feature for displaying directed-speech captions.
Use human captioning or review where stakes or accuracy needs require it. Follow accessibility guidance for synchronized captions and meaningful sound information.

ASR memetakan audio lisan ke teks dan merupakan dasar dari alat teks langsung.
NCRA describes CART as a human captioning workflow using a stenotype machine, computer, and realtime software; this does not imply a universal accuracy ranking.
Microsoft Speech documents intermediate Recognizing results that can change while processing audio, followed by a final Recognized result for an utterance. Other systems may expose different interfaces.
Tingkat Kesalahan Kata menghitung penyisipan, penghapusan, dan penggantian untuk mengukur seberapa akurat transkrip.
Microsoft’s real-time diarization example assigns labels such as Guest-1 and Guest-2 to transcribed speech. A speaker label is not proof of a person’s identity.
