What is the AI voice, you might ask?

Well, the AI voice is a simple conversational AI tool that uses voice commands to record and interpret a piece of given information.

This is artificial intelligence converting automated speech recognition into text-to-speech generation.

With the use of AI voice, users no longer need to worry about recording their voices as voice-overs for their presentations.

The AI voice can easily understand natural languages and can interpret them just the same way a typical human would.

For this reason, users only need to simply insert it into their presentations, which will be explained below, and they are good to go.

How to do a voice-over on PowerPoint

Doing a voice-over on PowerPoint is quite seamless once you get the hang of the steps involved.

To completely understand how to do this, simply follow the steps below:

Step 1: Create or open a PowerPoint presentation

Here you would have to create a new PowerPoint presentation if you haven’t already created one and add all the necessary images to the slides.

Otherwise, if you already have a presentation handy, you can just open it right away.

Step 2: Add your script

Here, you will need to type out your script on each slide, but if your script has been written already, simply proceed to insert it into the PowerPoint presentation.

Also, ensure that you create a new audio block for each slide, especially if you do not plan on using the same audio for all the slides.

However, if you plan on using the same audio for your slides, you can simply use the same audio block for all the slides.

This is to ensure that the narration and the imagery are perfectly aligned to make for an appealing presentation.

Step 3: Choose the AI voice to use as a voice-over for the presentation

This is where things get interesting. Rather than having to record your voice, you could simply proceed to select an AI voice to make use of.

Interestingly, has different types of AI voices based on different categories you can make use of, such as multiple languages, accents, gender, etc.

Once you have selected a voice, ensure that you listen to it by playing the sample from the dropdown or simply pressing the button next to the text block to do so.

This is to ensure that you are comfortable with the sound and the texture of the AI voice.

Note: You could also add background music to your presentation at this point.

Simply go to the menu on top, select Background Music, and then upload any track of your choice if you feel the need to do so. Otherwise, leave it as it is and proceed to step 4.

Step 4: Check that the AI voice and visuals are properly timed

You should adjust the AI voice and visuals to ensure that they have the same timing.

For instance, a visual that has been scheduled to last for 5 seconds on the screen needs to have an AI voice that would last for the same duration as well.

To adjust the timing, simply change the size of the image blocks in the bottom panel. You can match the size of every slide block with its narration timing or add pauses as required.

To add pauses, simply increase the size of the voice block beyond the narration time.

Step 5: Render and download the video

Once you are done adjusting the timing of the AI voice and visuals, you now have to render it in a video format.

If you have chosen a background music track along with a voice-over for your presentation, select the amount of emphasis you want to give to each using the slider on the right side.

The closer the slider is to the voice, the more prominent will be the voice-over to the music. You can also choose the audio channel type (mono or stereo) before rendering.

Once you are done with this, your voice-over presentation is ready and you can now proceed to check the preview.

When checking the preview, ensure you play the video so that you can take a look at the timing of the slides with the voice-over to ensure they are well-timed.

If you wish to make changes to the slides or any part of the script, simply,
Edit the text, click the Render Audio button, resize the slide and audio blocks, and then click the Build Video button.

You can repeat the steps to make as many changes to your script as you like.

Once you are done, you can export your voice-over presentation in an MP4 format.
