Top 5 AI Presentation Video Generators with TTS and Avatar Slide Narration
1. Synthesia
Synthesia is an easy-to-use AI video generator with text-to-speech functionality for presentations. You can quickly upload a PowerPoint presentation, choose a voice for text-to-speech narration and select any language. Pus, you can include an AI avatar who will appear on screen and present your slides. You can also continue without an avatar while keeping TTS narration and closed captioning. Synthesia offers plenty of customizable settings, including changing the avatar’s voice, appearance and location on screen. In addition, there are ample language, translation and design options, making it a great tool for universal business presentations and personal uses alike.
How to generate an AI video presentation with Synthesia
First, navigate to New Video or click directly on the Import PowerPoint icon. Simply upload or drag and drop your file and Synthesia will automatically convert it to a video.
Next, you can choose an AI avatar or start typing a script for each slide. Synthesia doesn’t automatically read the content on your slides, so you’ll have to either type out a script for TTS narration, or copy and paste the desired text. Subsequently allowing your AI narrator to go in depth and tell a story for each slide.
Furthermore, you’ll notice plenty of editing tools where you can change the narration language, voice style, duration, transitions and more. You can even add background music.
Once you’re happy with the script in each slide, you can start customizing your avatar. Synthesia’s easy-to-use editor allows you to click directly on the avatar and resize them, move them or leave them hidden. Just as with the language selector, you can pick from a wide variety of realistic avatars.
When you’ve finished customizing your script, avatar and video design, click on Generate in the top right corner to export your presentation as a fully functional AI video.
Synthesia overall
Synthesia’s ability to convert presentations into professional videos with realistic AI narrators and multilingual TTS makes it an ideal tool for creating polished marketing videos, training materials or business updates.
Some unique features in the paid plan include the ability to “clone” yourself and make an avatar in your likeness, as well as clone your own voice to generate TTS. The presets all sound and look great, but if you want to automate more personal presentations, this is a great feature.
Pros: Easy to use and closed captioning (CC) is automatically generated, which makes it easy to follow along.
Cons: While Synthesia automatically generates a video with your presentation content, you still need to enter or paste a script for each slide. Although this might create an extra step, but it’s still helpful for when you want to narrate a longer story over slides with minimal text.
