Top-10 Resources for AI Tools for English Presentation Practice

Synthesia AI Video Generator

Description:

Synthesia AI Video Generator builds a narrated video from a prompt, a script or an uploaded document. Published by Synthesia, the platform presents an AI avatar who speaks the words, with pre-built templates and libraries, roleplays and surveys, dubbing into other languages, and a share link for finished videos. Examples shown cover onboarding, training and marketing.

Limits of the Free Tier Plan: The Basic plan costs nothing and gives five hundred credits a month, the pre-built libraries, templates, roleplays and surveys, and a share link for your videos, which carry a Synthesia watermark. Downloading a video, removing the watermark and the larger credit allowances come with the paid plans.

Access: Free Tier Level: Intermediate (B1-B2) & Advanced (C1-C2) Format: Interactive Tool / Video Written for: General resource (helpful for professionals) English Variant: US

How It Helps Your Business English

What this resource offers:

The page opens the generator itself: a box where you enter a prompt, paste a script or upload a file, beside worked examples for an onboarding welcome, a training explainer, a marketing clip and cinematic scenes. Tabs separate work videos from creative ones, and links lead to sessions, the API, the resource library and the pricing plans.

How to use this resource:

You paste the script of a talk and watch an avatar deliver it, which lets you hear the length of your sentences and the places where the wording turns clumsy when spoken. Uploading a document instead gives you a first draft to tighten. Dubbing the same script into another language puts the two versions side by side, so you can compare how the same point is phrased.

Note:

ESLBusiness.com earns no commission if you upgrade to a paid plan.
