In an increasingly collaborative world, webcasts and webinars are essential for sharing knowledge and information. When people from different countries and cultures come together, barrier-free communication options are more important than ever. This is where live transcription comes into play. It is one building block among several — another is accessible presentations, where the slides sit beside the video as text instead of as pixels inside it. SlideSync offers high-quality real-time transcription that adds real value to your online event. In this post, you’ll learn everything you need about our live transcription feature and why it’s essential for your event.

What are live captions
and what is their significance?

Live transcription produces real-time captions of spoken words, displayed on screen as the speaker talks. They enable viewers to better understand spoken language by providing the spoken text in a readable form. They are particularly important for people with hearing disabilities who rely on visual support to understand the content. In addition, viewers with different language skills or in environments where it is difficult to hear the audio clearly also benefit from live captions. They make it easier to follow the content and to understand it.

Live transcription on SlideSync

SlideSync uses advanced technologies such as automatic speech recognition (ASR) and machine learning to create accurate, high-quality captions for webcasts in real time. The process includes:

• Audio recognition: SlideSync captures the spoken word during the webcast and converts it to text.
• Synchronization: The software synchronizes the text with the audio and video transmission and ensures that the captions appear at the same time as the spoken word.
• Subsequent editing: You have the choice to edit and enhance the generated transcript after the webinar or webcast before publishing it for SEO purposes.

Live captions — advantages and benefits

Using live captions with SlideSync offers numerous benefits, including:

• Accessibility: Live captions enable people with limited hearing or different language skills to participate in your event and better understand the content.
• Expanded reach: Integrate live captions to reach a broader, international audience.
• Improved intelligibility: Live captions ensure that your content can be understood even in noisy or acoustically unfavorable environments.
• Inclusion: By using captioning, you show that your event is open to all and that you care about the needs of your participants.

Live captions or a spoken translation — which do you need?

Live captions deliver running text. For attendees who cannot or would rather not read along, and for an audience in another language, a spoken alternative has been available since August 2026: an automatically generated audio track laid over the original — without an interpreter booth and without extra equipment.

What that AI audio track does, what it costs and where its limits are — in particular when a human simultaneous interpreter remains the better choice — is covered on its own page: AI simultaneous interpretation with Gemini AI Translate. If you need translated text rather than an audio track, live translation is the page for that.
