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, play.ht 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.

How to do a voice-over on Google Slides

Adding a voice-over to Google Slides is mostly the same as adding a voice-over to PowerPoint, except for some minor differences.

All you need to do to add a voice-over to Google Slides is to head on over to play.ht to add human-like AI voices to your Google Slide presentation directly within Google Slides.

With this, you do not have to make any recordings whatsoever as it is quite fast and seamless.

There are also a lot of voice and narration options to choose from, and you can make post-edits quickly without the need to re-record.

Deciding to make use of an AI voice only takes you a few minutes, and you are good to go.

Here are the steps below:

Step 1: Make a Google Slides presentation

The first thing you need to do is to create a presentation, making sure that all the slides are in order and that the length of your presentation corresponds to the allotted time.

Step 2: Write a script for each Google Slide

Here, you would need to have a script for each of the Google slides and also know what to say for each of them as well.

Step 3: Create a great audio voice-over for each Google Slide

This is where Play.ht comes in. With Play.ht, you can create excellent audio voice-overs in MP3 and WAV formats that are compatible with Google slides.

If you have multiple audio files, do well to categorize them carefully so that you know which file goes with which slide in your presentation.

Step 4: Upload the audio files to Google Drive

You can use the Folder or File upload option on the left of Google Drive to create a new folder and upload your files into one folder.

It is a good idea to keep the audio files in the same folder as the Google Slide presentation.

Step 5: Insert the audio files one slide at a time

After uploading the audio files to Google Drive, all you need to do is to insert the files one slide at a time by selecting a slide, and proceeding to insert them in the main menu, after which you select the audio option.

This will open up a pop-up box like this where you can see all the audio files. Then you select the respective audio files for each of the respective slides before proceeding to upload.

Step 6: Configure the voice-over audio format options

Once you select the voice icon, you will see a Format Options menu open up on the right. These give you a whole range of choices in terms of playing the narration or other audio files with your presentation.

Step 7: Preview the Google Slides with audio voice-over

To preview the presentation along with the voice narration, go to “View” on the main menu and select “Present” from the options.

This will open up the slides in full-screen mode and play the narration along with the file.

Step 8: Share your presentation

Google Slides, along with the narration, can be shared via the Share button on the top right corner of your presentation.

At present, you can only share your presentation as Google Slides does not have the option of exporting your presentation as a video like that of PowerPoint.
