Method 2: Use a dedicated captioning platform alongside Zoom
Zoom's built-in captions are convenient but have limits: accuracy varies by speaker and audio quality, the transcript is only saved if you opt in beforehand, and translation is paywalled behind higher-tier accounts. For events you'll archive, publish, or repurpose into content, a dedicated captioning platform that runs alongside Zoom usually pays for itself.
The setup pattern is the same regardless of which dedicated platform you use: the host's machine captures the audio (which is going to Zoom anyway), the captioning platform produces a separate viewer link, and you share that link with attendees in the meeting chat at the start. Captions appear on a second screen — usually attendees' phones — while the video stays on Zoom. After the meeting, the dedicated platform produces a searchable transcript at a stable URL.
EventRecast is one such platform. It captures Zoom audio from the host machine, streams real-time captions to attendees on any device, generates an AI summary the moment the meeting ends, and keeps a searchable transcript for as long as you need it.
Which method to pick
For internal team meetings, daily standups, and one-off calls where the captions are situational accessibility (someone in a noisy environment, a participant with hearing differences), Zoom's built-in option is enough. Latency is acceptable, accuracy is workable on clean audio, and there's no extra setup.
For external webinars, sales pitches, customer presentations, town halls, and any meeting that becomes content afterwards, a dedicated platform is worth the marginal effort. You get higher accuracy (especially with custom vocabulary for product names), real-time translation, a transcript you can search and publish, and engagement analytics that Zoom's built-in option doesn't provide.
For events with explicit accessibility requirements (deaf or hard-of-hearing attendees registered, ADA-compliance-mandated public events), most accessibility coordinators recommend a dedicated platform alongside ASL interpreters. The combination meets WCAG 2.2 captioned-media criteria and goes beyond the legal floor.
Multi-language attendees
Zoom's translated captions feature is available on Business, Education, and Enterprise plans. It supports a fixed set of language pairs and runs on top of Zoom's automated captions, which means translation accuracy is bounded by source-caption accuracy. For most internal meetings this is fine; for international audiences whose first language isn't English, dedicated platforms typically produce noticeably better translations because their source captions have higher accuracy to begin with.
If your audience spans many languages, a dedicated platform with viewer-side language selection (each attendee picks their own language) is usually a better experience than running multiple Zoom translated-caption languages.
