Text-to-speech (TTS) technology is increasingly integral in tools like Microsoft PowerPoint, enhancing accessibility and understanding of presentations. Here’s why and how to use this feature effectively:

Why Use Text to Speech in PowerPoint?

TTS technology converts written text into spoken words, simplifying the absorption of content in presentations. This is particularly beneficial in business settings where PowerPoint is a staple for conveying complex ideas visually and interactively. TTS not only aids in maintaining audience engagement but also supports those with disabilities such as dyslexia or visual impairments, facilitating a more inclusive learning and working environment.

Benefits of Text to Speech Technology

The ability of a computer or device to vocalize text through TTS improves accessibility, enhances comprehension, and fosters a more effective learning atmosphere. It’s useful across educational and professional domains, helping individuals save time and digest information more efficiently.

Customizing PowerPoint Presentations

PowerPoint allows extensive customization to reflect personal or corporate styles. Users can select various templates, integrate multimedia like photos and graphics, and even add voice-overs. Sharing presentations online for collaborative viewing or editing is another significant feature.

How to Implement Text-to-Speech in Your Presentation

1. Activate Text-to-Speech: Open your PowerPoint presentation, select the slide or text box you wish to read aloud, and click the “Speak” icon (resembling a microphone) in the toolbar.
2. Customization: Adjust TTS settings such as voice speed, language, and speaker accent by clicking the “Settings” icon (shaped like a gear). Choices may include different accents or gendered voices.

Using External TTS Software

Beyond PowerPoint’s built-in capabilities, external TTS applications like Wavel AI offer additional features, supporting multiple languages and providing options like voice speed adjustments. These tools can be particularly helpful for proofreading and catching grammatical errors by reading text back to you.

Text-to-Speech vs. Dictation Features

It’s important to distinguish between TTS and dictation. TTS involves your device reading written text aloud, while dictation refers to speaking to your device to have it type text for you, a feature found in various Microsoft Office applications.

Using TTS in tandem with dictation can greatly enhance productivity and comprehension, benefiting users in both academic and professional settings.
