Live Captions
The AI-powered real-time captioning feature takes spoken language and shows it as text, in real time, helping viewers quickly understand what’s being said in the stream.
It is designed for live events that demand precision, accessibility, and scalability.
This feature is available via API only and does not include a built-in UI.
Integration into your playback system or application is required.
Benefits
- Provides dynamic and accurate readable content to enhance user engagement
- Improves the user experience by letting viewers follow along without sound
- Helps users hard of hearing to stay focused on what’s being said
To enable and use the live captioning feature, the following requirements must be met:
- Live captions must be enabled for your organisation
- Pricing and payment options must be set up, as live captions is a business option
- An Automatic Speech Recognition (ASR) engine type must be selected
Some of our ASR services require 24 hours’ prior notice. Please contact our Sales team to find the best setup for your organisation and to receive comprehensive information about ASR types based on your use case.

3. Stream & Consume Captions
- Live captions and caption switcher are not part of the H5Live Player and are not embedded automatically.
- Captions are generated in real time and made available through a dedicated output channel.
- To allow end users to enable/disable captions, you must integrate captions functionality into your playback system or application. Contact nanocosmos support for detailed integration instructions.
- Live captions start automatically with the stream
- The first captions appear within 5–7 seconds depending on the ASR provider
- Captions stop automatically when the stream ends
If your stream is already live and you change live caption settings, updates will only take effect after you stop and restart the stream.
