With Live AI Subtitles, the OnlineWebinar.com platform converts spoken audio during webinars and live streams instantly into clear, readable captions. Powered by an advanced AI language model, participants can follow every session effortlessly, even without sound or when content becomes complex.
How Live AI Subtitles work
Real-time speech recognition
Audio from one or multiple speakers is continuously analyzed by an AI model trained to recognize human speech across different accents, speaking speeds, and styles.
Context-aware transcription
Unlike traditional speech-to-text systems, the language model understands context and sentence structure, resulting in fewer errors when handling terminology, names, and longer explanations.
Instantly visible for participants
Subtitles appear live within the webinar interface with minimal delay. Participants can easily toggle subtitles on or off, based on their personal preference.
Note: real-time subtitles are always an interpretation of live speech. For maximum accuracy, a refined transcript can be generated after the event using the full recording.
Language support & translation
- Support for converting spoken language into live subtitles
- Suitable for international and multilingual audiences (depending on language settings)
Accessibility & inclusion
Live AI Subtitles improve accessibility for:
- Participants with hearing impairments
- Viewers in noisy environments
- Non-native speakers
- Organizations aiming to comply with widely used WCAG accessibility guidelines
This ensures your webinars are inclusive by design.
Additional capabilities
- Post-event transcript enhancement
After the webinar, the AI can reprocess the full recording to generate a more accurate transcript. - Downloadable text files
Transcripts can be exported for documentation, content creation, or compliance purposes. - Edit & reuse for on-demand
Improve the transcript manually and re-upload it to power perfectly captioned on-demand webinars.
Value for organizers
- Increased engagement and comprehension
- A more professional experience without interpreters or manual captioning
- Additional reusable content from a single webinar
