PowerPoint 是一款应用程序，可让您创建引人入胜的演示文稿^{(an engaging presentation)}并将其交付给观众。但是，如果观众不在同一个房间，或者您将其作为链接或附件^{(link or attachment)}发送怎么办？

这就是为什么在PowerPoint幻灯片计时中添加音频旁白很有帮助和有用的原因。您可以从演示文稿中录制旁白，以便在观众观看时播放。在您的Powerpoint 演示文稿或视频^{(Powerpoint presentation or video)}中添加画外音旁白会将其变成常青的独立内容。

本文将讨论如何为Windows 10的^{(Windows 10)}Powerpoint 演示文稿^{(Powerpoint presentation)}添加音频旁白。

测试您的默认麦克风^{(Test Your Default Microphone)}

您首先需要的是一个工作麦克风。今天的大多数计算机都带有内置麦克风。如果您打算使用计算机默认麦克风^{(computer default microphone)}，则无需采取额外步骤来添加麦克风。

但是，您确实要确保它正常工作并且声音足够大，可以听到。要设置您的默认麦克风^{(default microphone)}，请对其进行测试以确保其正常工作。要自定义属性，请按照以下步骤操作。

• 首先在搜索栏中输入设置^(Settings)。
• 单击系统^(System)>声音^(Sound)。

• 在输入^(Input)下查找配置麦克风的选项。单击^(Click)选择您的输入设备^{(Choose your input device)}下的下拉菜单以分配您的默认麦克风。
• 如果您只有一个麦克风，则没有任何选择。要打开其他麦克风设置，请单击设备属性^{(Device properties)}>其他设备设置^{(Additional device settings)}。

• 启用或禁用扬声器并访问“^{(speaker and access audio driver information)}常规^(General)”选项卡下的音频驱动程序信息。
• 收听^(Listen)选项卡使您可以允许或拒绝您的麦克风收听扬声器。
• 在Levels^(Levels)下调整麦克风音量和平衡设置^{(microphone volume and balance settings)}。
• 在“高级^(Advanced)”选项卡下更改默认采样率和位^{(default sample rate and bit)}深度。
• 如果在您的计算机上启用，空间音效^{(Spatial sound)}可以增强音频体验。 

要测试您的麦克风，请返回输入^(Input)部分。如果它不起作用，您可以使用“疑难解答”^{(Troubleshoot)}按钮尝试解决问题。

安装 USB 麦克风^{(Install a USB Microphone)}

• 要启用您的麦克风^{(enable your microphone)}，首先，将USB 麦克风^{(USB microphone)}插入您的计算机。然后右键单击任务栏上的音量图标^{(volume icon)}。 
• 单击声音^(Sounds)。

• 在录音^(Recording)选项卡下，选择您要设置的麦克风，然后单击配置^(Configure)。 
• 在配置您的语音识别体验^{(Configure your Speech Recognition experience)}下，单击设置麦克风^{(Set up microphone)}。

• 安装向导^{(setup wizard)}启动后，选择您要安装的麦克风类型，然后单击下一步。^(Next.)

• 您看到的下一个屏幕将提供有关使用麦克风的提示以及一些可供阅读的文本以测试您的设置。 
• 按照向导中的说明测试麦克风以确保其正常工作。  

将 USB 麦克风设置为要使用的输入设备^{(Set USB Microphone As Input Device To Use)}

如果要使用刚刚设置的外接USB 麦克风录制旁白，则需要将其设置为^{(USB microphone)}输入设备^{(input device)}。

• 右键单击^{(Right-click)}任务栏右侧的音量图标，^{(volume icon)}然后单击^{(taskbar and click)}打开声音^{(Open Sound)}设置。  

• 从声音设置窗口^{(Sound Settings window)}，向下滚动到输入^(Input)并勾选选择您的输入设备^{(Choose your input device)}下的框。 
• 选择您的USB 麦克风^{(USB microphone)}作为输入设备^{(input device)}。

排练和做笔记^{(Rehearse & Take Notes)}

现在您的麦克风已经设置好并经过测试，与其直接进入并开始录音，不如花时间练习您要说的内容。

记笔记、写脚本并排练时间以节省时间、减少错误并确保您的音频听起来流畅自然。

现在您可以开始录制了。

打开录制选项卡 (Office 365)^{(Turn On the Recording Tab (Office 365))}

• 要打开“录制”选项卡^{(Recording tab)}，请导航到“文件^(File)”，单击“选项^(Options)” > “自定义功能区^{(Customize Ribbon)}” > “录制”^(Recording) > “确定^(OK)” 。

如何为一张幻灯片录制音频旁白^{(How To Record An Audio Narration For One Slide)}

向PowerPoint 演示文稿^{(PowerPoint presentation)}添加音频的最简单方法是一次录制一张幻灯片。 

• 首先选择要添加音频的幻灯片。

• 单击顶部导航栏中的^{(bar navigation)}播放^{(Playback )}，然后勾选显示期间隐藏^{(Hide During Show)}。

为整个幻灯片录制音频旁白 (Office 365)^{(Record An Audio Narration For An Entire Slideshow (Office 365))}

• 单击顶部导航中的录制^(Recording)，然后单击录制幻灯片^{(Record Slide Show)}。 

• 选择从当前幻灯片^{(Record from Current Slide)}录制或从开头录制^{(Record from Beginning)}。幻灯片将在录制窗口^{(Recording window)}中打开。

• 左上角有用于录制、暂停、停止和播放的按钮。单击^(Click)红色圆形按钮开始录制。将有三秒钟的倒计时让您做好准备。
• 您正在录制的幻灯片将显示在窗口的主窗格中。要前进到下一张幻灯片，请使用窗口右侧的箭头。要移至上一张幻灯片，请使用左侧的箭头。带有Office 365的^{(Office 365)}Powerpoint将自动记录您在每张幻灯片上花费的时间。这包括您设置的任何动画。
• 使用屏幕右下方的按钮打开或关闭麦克风、摄像头和摄像头预览^{(camera preview)}。如果您选择重新录制部分或全部旁白，Powerpoint将删除旧版本，以便您重新录制。
• 完成录制后，单击录制窗口^{(recording window)}左上角^{(left-hand corner)}的方形按钮。

• 每张幻灯片的时间都将显示在“幻灯片分类器”视图^{(Slide Sorter view)}中。要查看您的时间安排，请单击查看^(View)>幻灯片排序器^{(Slide Sorter)}。

• 从下图中的“幻灯片分类器^{(Slide Sorter )}”视图中查看幻灯片下的时间安排。

How To Add Audio Narration To a Powerpoint Presentation

PowerPoint is an app that enables you to creatе and deliver an engaging presentation to an audience. But what if the audience is not in the same room or you are sending it as a link or attachment?

This is why adding audio narration to PowerPoint slides timings is helpful and useful. You can record the narration from inside your presentation so that it plays while viewers watch. Adding voice-over narration to your Powerpoint presentation or video will turn it into evergreen stand-alone content.

This article will discuss how to add audio narration to a Powerpoint presentation for Windows 10.

Test Your Default Microphone

The first thing you will need is a working microphone. Most computers today come with a built-in microphone. If you plan to use your computer default microphone, you don’t have to take additional steps to add a microphone.

However, you do want to make sure it’s working and loud enough to hear. To set your default microphone, test it to make sure it’s working. To customize the properties, follow the steps below.

• Start by typing Settings in the search bar.
• Click on System > Sound.

• Look under Input for options to configure your microphone. Click the dropdown menu under Choose your input device to assign your default microphone.
• If you only have one microphone, there is nothing to select. To open additional microphone settings, click on Device properties > Additional device settings.

• Enable or disable speaker and access audio driver information under the General tab.
• The Listen tab enables you to allow or deny your mic to listen to the speakers.
• Adjust the microphone volume and balance settings under Levels.
• Change the default sample rate and bit depth under the Advanced tab.
• If enabled on your computer, Spatial sound can enhance the audio experience. 

To test your microphone, go back to the Input section. If it’s not working, you can use the Troubleshoot button to try to resolve the issue.

Install a USB Microphone

• To enable your microphone, first, plug in the USB microphone to your computer. Then right-click on the volume icon on the taskbar. 
• Click on Sounds.

• Under the Recording tab, choose the microphone you want to set up and click Configure. 
• Under Configure your Speech Recognition experience, click on Set up microphone.

• When the setup wizard starts, choose the type of microphone you are installing and click Next.

• The next screen you see will provide tips for using your microphone and some text to read to test your settings. 
• Follow the instructions from the wizard and test the microphone to make sure it is working correctly.  

Set USB Microphone As Input Device To Use

If you want to use the external USB microphone you just set up to record your narration, you need to set it as the input device.

• Right-click on the volume icon on the right side of the taskbar and click on Open Sound settings.  

• From the Sound Settings window, scroll down to Input and tick the box under Choose your input device. 
• Select your USB microphone as the input device.

Rehearse & Take Notes

Now that your microphone is set up and tested, instead of jumping right in and starting to record, take the time to practice what you are going to say.

Take notes, write out a script, and rehearse the timings to save time, minimize errors, and ensure that your audio sounds fluid and natural.

Now you are ready to start recording.

Turn On the Recording Tab (Office 365)

• To turn on the Recording tab, navigate to File, click Options > Customize Ribbon > Recording > OK.

How To Record An Audio Narration For One Slide

The easiest way to add audio to your PowerPoint presentation is to record one slide at a time. 

• Start by selecting the slide where you want to add the audio.
• Navigate to Insert > Audio > Record Audio.

• Choose a name for your voiceover and replace Recorded Sound with the name.  

• To start your recording, click the button with the red dot. Read from your script and click the stop button when finished. 
• The stop button is the middle square and will be highlighted in red while you are recording.

• To hear your recording, press the play button. If you like how it sounds and want to keep it, click OK.

• You can also hear the audio by clicking on the embedded audio icon on your slide. It will open a bar underneath where you can play your audio.

• You will now have a visible audio icon on your slide. To hide this icon for your final presentation, click on it. 
• Click Playback in the top bar navigation, and tick off Hide During Show.

Record An Audio Narration For An Entire Slideshow (Office 365)

• Click on Recording from the top navigation, and then Record Slide Show. 

• Choose either Record from Current Slide or Record from Beginning. The slideshow will open in the Recording window.

• There are buttons on the top left for recording, pausing, stopping, and playing. Click on the red, round button to start recording. There will be a three-second countdown for you to get ready.
• The slide you are recording will show up in the main pane of the window. To advance to the next slide, use the arrow on the right side of the window. To move to a previous slide, use the arrow on the left. Powerpoint with Office 365 will automatically record the time you spend talking on each slide. This includes any animations you have set up.
• Use the buttons on the bottom right-hand side of the screen to toggle your microphone, camera, and camera preview on or off. If you choose to re-record part or all your narration, Powerpoint will erase the old version to enable you to record again.
• When you finish recording, click on the square button at the top left-hand corner of the recording window.

• The timings for each slide will show up in the Slide Sorter view. To see your timings, click on View > Slide Sorter.

• See the timings under the slides from the Slide Sorter view in the image below.

Preview Your Slide Show

• To preview your slideshow with your narration, animations, and timings (set up before you started recording), click Slide Show from the top bar navigation. Make sure you are on the Home tab.
• Choose From Beginning or From Current Slide.

• To hear the audio for a single slide, go to Normal view, click on the sound icon and click Play. Note that recorded animations won’t show up when previewing from a single slide.

Manually Set Slide Timings

• You can also manually set your slide timings to sync with your narrations. To do so, select the slide from Normal View and then click on Transitions. 
• From the Timing group, select the After check box under Advance Slide.

• Enter how long you want the slide to stay on the screen before moving onto the next. Do this for every slide you want to use manual timings.

Publish Your Presentation For Sharing

You can save your presentation as a Powerpoint Show (.ppsx) or a video to share it with others. When a viewer opens a slideshow file, it will immediately open in slideshow mode.

To save your presentation, go to File, Save As and select the format from the dropdown menu.

If your presentation is huge and you want to send it as an email attachment, you might need to compress the file. A better option is to upload it to Dropbox, OneDrive, or Google Drive, and send the link to the desired recipients.
