OpenAI GPT-5.4 and gpt-5.4-mini Support Released
Now supporting OpenAI GPT-5.4 and gpt-5.4-mini for higher-quality speech script generation.
We have added OpenAI's latest model "GPT-5.4" and the lightweight, faster "gpt-5.4-mini" to SpeechSlide AI.
You can now select GPT-5.4 and gpt-5.4-mini for speech script generation, alongside the existing GPT-5.2 and GPT-5.1 options, so you can choose the model that best fits your needs. GPT-5.4 is the default selection for new script generation. If speed is your priority, please try gpt-5.4-mini as well.
With SpeechSlide AI, you simply upload your PDF or PowerPoint slides, and the AI reads the content, automatically generates a speech script, and creates a narrated MP4 video with AI voice. Generated scripts can be freely edited in the editor, so you can tailor the result for anything from sales introduction videos to formal presentations.
Please try script generation with the latest models.
