AI SUBTITLES GENERATION & TRANSLATION
Generate subtitles in real time and translate them into multiple languages
EngageStream uses AI to generate subtitles as the event is taking place. Once the spoken language has been selected, subtitles can be translated into multiple languages simultaneously, allowing attendees to follow the presentation in their preferred language.
At present, each webcast supports one spoken source language. As long as presenters speak the selected language throughout the event, subtitles can be translated into as many target languages as required.
- AI-generated live subtitles
- Real-time subtitle translation
- Multiple translated subtitle languages
CUSTOM GLOSSARY
Improve AI accuracy with your own terminology
Corporate presentations often include company names, product names, executive names, financial terminology and acronyms that automatic speech recognition may not recognise correctly.
To improve subtitle quality, EngageStream allows organisers to upload a custom glossary before the event. The glossary provides the AI with important terms that should be recognised during transcription and translation.
- Custom glossary for company terminology
- Support for names and surnames
- Recognise acronyms and abbreviations
SIMULTANEOUS INTERPRETATION
Support international audiences during live and on-demand events
For events requiring spoken language interpretation, the platform can also support simultaneous interpretation delivered by professional interpreters.
Interpreters can work either remotely or on location, allowing attendees to switch between available audio languages during the webcast.
- Human simultaneous interpretation available
- Remote or on-site interpretation
- Language selection during the webcast
“The platform allows us to go beyond a standard webinar format and adopt a more engaging, "TV-show" style approach, with professional production, branding, and multilingual delivery.”
