Speaker notes in Google Slides hold presenter-facing explanation separately from the visible slide content. They are useful for transitions, supporting details, and delivery prompts. Keep the audience’s essential message on the slide, and do not treat notes as a confidential storage area inside a shared presentation.
Google Slides can dictate speaker notes using a supported desktop browser and microphone. This is useful for drafting a spoken explanation in a natural voice. The feature types into notes; it is not a command to place live narration into every text box on the slide.
Dictated Google Slides speaker notes often need corrections to names, figures, or technical wording. Use normal editing to fix those passages. Google’s shared voice-typing help contains editing commands for Docs, but explicitly says voice commands are not available in Slides speaker notes.
Live captions in Google Slides display recognized speech during a presentation. They can help an audience follow the speaker, but they are machine-generated and may contain errors. They are not stored as a transcript according to Google’s caption guidance.
Caption position and size affect how easily viewers can follow a Google Slides presentation. Adjust them when captions cover important content or are difficult to read. The goal is a useful combination of speech text and slide information, not merely an enabled caption switch.
Missing Google Slides captions can result from browser support, microphone access, inactivity, or organization policy. Check those conditions before changing the presentation’s contents. A caption control that is enabled does not prove that speech is reaching the recognition service.
Alternative text describes the meaningful information in a Google Slides image for people using assistive technology. It is particularly important when a graphic carries data or an explanation that is not available elsewhere in text. An image’s filename is rarely an adequate description of its purpose.
Google Slides screen-reader support adapts the editor for working with assistive technology. Enable it before evaluating keyboard navigation or slide announcements. The setting is part of an accessible editing workflow; it does not automatically repair unclear reading order or missing alternative text in the presentation.
Contrast and explicit labels help a Google Slides audience read and interpret information. A pale caption or a color-only status can be difficult to understand even when the slide looks attractive in the editor. Review both visual separation and the words carrying the message.
The filmstrip is the list of slide thumbnails in Google Slides, and it provides a useful navigation route for screen-reader users. It is separate from the canvas, where individual slide objects are edited. Move focus deliberately so a navigation key does not act on the wrong editing area.
