So You Want to Translate PowerPoint Materials! Effective Solutions and Useful Translation Tools

1. Common Challenges in Translating PowerPoint Materials

When translating PowerPoint materials, there are the following challenges.

●I want to quickly and efficiently translate PowerPoint presentations.

PowerPoint offers an automatic translation tool as a standard feature, but there are limitations in accuracy and usability. To perform automatic translation, you need to select the text to be translated, which can be time-consuming if there are multiple text boxes within a single slide, as each piece of text must be selected individually.

●I want to translate all PowerPoint slides at once

If you want to translate all the slides included in the presentation, you need to select and translate each text box for each slide, and then repeat the same process for all slides. For presentation materials that contain many slides, this task can be very time-consuming.

●I want to translate with ChatGPT but do it efficiently

It is also possible to use the AI chat service ChatGPT for translation, but you need to copy the text in PowerPoint and paste it into the ChatGPT chat box to instruct it to translate.

●I want to know about tools that can translate PowerPoint for free

In addition to the translation tool built into PowerPoint, you may consider using free translation tools available on the internet. However, free translation tools have limited features such as glossaries, so it is necessary to manually correct product names and service names. Additionally, there are security concerns when using these tools for business purposes, as the input information may be reused for service improvement, meaning that confidential information may not be retained.

●I want to know an easy way to produce in-house without relying on a translation company

Requesting a translation company can incur costs and may take time to meet deadlines. Additionally, for specialized content or company-specific terminology, it can be difficult for external translators to achieve accurate understanding. If there are means to efficiently carry out translation work in-house, there are significant benefits in both cost and time.

2. How to Solve PowerPoint Translation Challenges

The first item for consideration is the translation tool that is standard in PowerPoint. This feature is available for free and may meet basic translation needs. Although there are limitations in usability and accuracy, it is sufficient for translating only certain texts.

While it is possible to consider using Copilot for Microsoft 365 for translation, when I actually tried it, it did not accept translation instructions like the following.

Instead, by entering 'Please translate the following into English' and then copying and pasting the text, it was possible to translate as shown below. I think it would be convenient if it could read the slides directly, but currently, copying and pasting the text is necessary.

Using add-ins is effective for streamlining translation work in PowerPoint. For example, MTrans for Office allows you to perform translation tasks directly within PowerPoint, enabling you to translate entire slides or presentations with a single click. There is also a PowerPoint version of DeepL. These tools come equipped with glossaries and auto-correction features, reducing the need for manual corrections and improving the efficiency and quality of translations.

3. Recommended Tools for PowerPoint Translation

We recommend MTrans for Office for PowerPoint translation. MTrans for Office is a translation add-in software for Microsoft 365 products (Word, Excel, PowerPoint, Outlook) that allows users to translate with a single click. It supports multiple translation engines (DeepL, Google, Microsoft, OpenAI) and maintains the layout and formatting of the file after translation.

4. Benefits of Using MTrans for Office

MTrans for Office is developed for corporations and offers various benefits for business use.

●Usability

The biggest feature of MTrans for Office is its excellent operability.

However, with MTrans for Office, translation is completed with just one click. Additionally, unlike the standard translation function in PowerPoint, MTrans for Office allows you to translate slides or the entire presentation with just one click.

●Maintain Layout

By using MTrans for Office to translate PowerPoint, the formatting such as slide layout, font settings, text size, and color scheme is preserved after translation, minimizing the time required for design adjustments.

●Translation Quality

In terms of translation quality, we utilize translation engines from DeepL, Google, Microsoft, and OpenAI. You can choose between DeepL's natural translations, Google and Microsoft's extensive language support, and the advanced translation and proofreading features of OpenAI's GPT engine, all tailored to your needs. This allows us to handle a wide variety of content, from technical documents to creative expressions.

●Security

We implement robust security features with consideration for corporate use. Translation data is encrypted during transmission through secure communication via the API. Additionally, we have commercial service contracts with each provider of the translation engine, ensuring that input and output data is not reused for model or service improvement. It is also possible to restrict usage locations through IP limitations.

●Terminology Management

The customizable glossary feature allows for the accurate management of company-specific terminology and product names. The glossary can be shared within the team, enabling multiple users to work with the same glossary. This helps maintain consistency in the company's branding and specialized terminology.

●Multilingual Support

We support over 30 language pairs, covering a wide range of languages including the major languages of Japanese, English, Chinese, and Korean, as well as European languages and other Asian languages. We appropriately address the unique writing systems and grammatical rules of each language, providing high-quality translations.

●Equipped with Generative AI

By connecting to the GPT-4o model that supports the AI chat service ChatGPT, you can utilize generative AI for tasks such as transcription of English emails, summarization of texts, and document creation in addition to translation. It comes with built-in prompts that assist with translation and writing, which can be executed with a single click. The prompts can also be customized.

●Automatic Post-Editing Function

Equipped with string replacement, regular expression replacement, and automatic correction features for translated text using generative AI. If you are repeatedly performing specific correction tasks after translation, such as standardizing the representation of characters and symbols or refining the expression of the translated text, you can set conditions to automatically correct the translated text.
