What It Is

SlideToTalk is an online tool that converts slides into narrated videos. Users can upload PPT, PPTX, PDF, JPG, or PNG files, then set the aspect ratio, edit narration, choose a voice, generate the video, and export it as an MP4. The page states that documents up to 50MB are supported, with HD, Full HD, and preview resolutions available.

Core Features

Its core feature is AI Narration: it can generate narration slide by slide, with support for “AI Generate All,” special instructions, a maximum character count per slide, retrying results, and applying generated text. On the voice side, the interface shows 10+ voices, while the pricing page further mentions 1,600+ AI voices and 48 languages. It also supports speech speed options of 0.5x/1.0x/2.0x, dual narrators, voice previews, pronunciation dictionary replacements, as well as background music and volume settings. The site provides a Chinese-language entry point, but it does not clearly explain the quality of Chinese voices, the underlying model, or the specific TTS provider.

Pricing and Limits

Pricing is relatively clear: the Free plan is $0/month and allows unlimited videos, but each video can have up to 5 pages. Starter costs $9.90/month, with 30 videos/month, up to 20 pages per video, and no watermark. Pro costs $19.90/month, with 100 videos/month, up to 50 pages per video, no watermark, and BGM access included. For short course materials and marketing assets, the barrier to entry is low, but longer presentations will be constrained by the page limits.

Pros and Cons

The main advantages are its simple workflow, support for common presentation and image formats, and multiple aspect-ratio outputs covering landscape, portrait, and square videos. It is suitable for quickly creating course videos, product explainers, and social media videos. The pronunciation dictionary is also practical for abbreviations, brand names, job titles, and similar terms. The drawbacks are that the collected information does not disclose details such as an API, team collaboration features, data privacy, payment methods, or refund policy, and there are no generated samples or quality evaluations shown. The accuracy and naturalness of the AI narration still need to be tested in practice.

Who It’s For and Access from China

SlideToTalk is better suited to teachers, trainers, marketers, sales teams, and individual creators who want to quickly turn existing PPT/PDF files into narrated videos. Access from mainland China cannot be determined from the available text, and payment methods are not disclosed. If network access or payment is restricted, alternatives to consider include Canva, Gamma, HeyGen, Synthesia, or China-based options such as 剪映 and 讯飞智作.
