AI-Powered Presentation Translator

Aspose.Slides Presentation Translation API: AI-Powered Multilingual Slide Translation

Aspose.Slides is a powerful API for programmatically managing PowerPoint presentations. In addition to creating, editing, and converting slides, it offers AI-driven features - such as the Presentation Translation API for multilingual slide content.

How it Works

Aspose.Slides does not include built-in AI capabilities but integrates with external AI models over the internet. This functionality is exposed via the SlidesAIAgent class, which uses IAIWebClient subclasses to communicate with AI services.

You can use the built-in OpenAIWebClient to connect to OpenAI’s API or implement your own IAIWebClient to use a different AI provider or language model.

Aspose.Slides handles the communication, parses the AI responses, and intelligently inserts translated content while preserving the original slide layout and formatting.

Note that the OpenAI API is a paid service, so you will need to create an account and supply your API key when using the built-in OpenAIWebClient.

Example

In this example, we translate a PowerPoint presentation into Japanese using the built-in OpenAIWebClient with a specified OpenAI model.

# Load a presentation to translate.
with slides.Presentation("sample.pptx") as presentation:

    # Create an AI client with OpenAIWebClient, specifying your model and API key.
    with slides.ai.OpenAIWebClient("gpt-4o-mini", "apiKey", "") as ai_web_client:

        # Initialize SlidesAIAgent with the AI client.
        ai_agent = slides.ai.SlidesAIAgent(ai_web_client)

        # Translate the presentation to Japanese.
        ai_agent.translate(presentation, "japanese")

        # Save the translated presentation as a PDF.
        presentation.save("sample_jp.pdf", slides.export.SaveFormat.PDF)
