PowerPoint 即時字幕與翻譯功能

為協助教師在遠距課程中提升課程無障礙服務，Microsoft 365 的 PowerPoint 提供「即時字幕與翻譯」功能。

當教師進行簡報時，PowerPoint 能夠將語音內容即時產生字幕，並可選擇是否翻譯為其他語言，方便不同語言背景或有聽力需求的學生即時理解課程內容。

📍 同步課程 可透過此功能即時顯示字幕，協助學生即時理解課程內容；

如有跨語言需求，也可啟用翻譯字幕，方便不同語言背景的學生參與課程。

📍 非同步課程 則可在錄製後補充字幕或翻譯，提升課程的可近性與易讀性。

✏️ 功能說明

• 語音字幕轉換：教師講課內容會即時轉換為螢幕字幕，方便學生同步閱讀。
• 語言翻譯支援：字幕可顯示為原語言，或翻譯為其他語言，協助跨語言溝通。
• 字幕位置調整：可設定字幕顯示於簡報畫面的上方或下方，視教學需求調整。

✏️ 使用條件

• 需使用 Microsoft 365 授權版本的 PowerPoint
• 需具備穩定的網際網路連線，因為功能依賴雲端語音辨識服務

✏️ 建議使用方式

• 說話時保持語速穩定、發音清楚，可提升字幕辨識正確度
• 減少背景雜音，以避免語音辨識失誤
• 建議於網路穩定的環境下使用，確保字幕即時顯示流暢

PowerPoint Live Subtitles and Translation Feature

To support faculty in enhancing accessibility in remote teaching, Microsoft 365 PowerPoint provides a “Live Subtitles and Translation” feature.

When giving a presentation, PowerPoint can automatically generate live subtitles from speech. Teachers may also choose to translate subtitles into other languages, making it easier for students from different language backgrounds or students with hearing needs to follow the lecture in real time.

📍 Synchronous courses – Subtitles can be displayed instantly during live classes, helping students understand the course content in real time. If cross-language communication is required, translation can also be enabled for multilingual participation.

📍 Asynchronous courses – Subtitles or translations can be added after recording, improving accessibility and readability of course materials.

✏️ Features

• Speech-to-text subtitles: Spoken content is automatically converted into subtitles for students to read in real time.

• Language translation support: Subtitles can be shown in the original language or translated into other languages to support multilingual communication.

• Subtitle placement adjustment: Teachers can set subtitles to appear at the top or bottom of the slide, based on teaching needs.

✏️ Requirements

• Microsoft 365 licensed version of PowerPoint

• Stable internet connection (since the feature relies on cloud-based speech recognition services)

✏️ Recommended Usage

• Maintain a steady speaking pace and clear pronunciation to improve subtitle accuracy.

• Minimize background noise to avoid recognition errors.

• Use in a stable internet environment to ensure smooth and real-time subtitle display.

✏️ Setup Steps

1. Open PowerPoint and click on “Slide Show.”
   

2. Next to “Always Use Subtitles,” click the dropdown arrow to access three settings: Spoken Language, Subtitle Language, and Subtitle Position.
   

   ⭐️ Step 1: Click the arrow next to Spoken Language and select the language you will speak during your presentation.

   ⭐️ Step 3: Choose the subtitle display position:

   • Below or above the slide: Subtitles overlap with the slide content.

   • Top or bottom of the screen: Subtitles do not cover the slide content.
