Siri, the popular virtual assistant, has taken on another role and it's in the realm of content creation. Siri voice generators allow creators on all platforms to add a similar voice to their videos.

You've likely noticed this edit taking off on TikTok. The text-to-speech feature converts text to a voiceover and you might hear something unexpected. The occasional flubbed words and monotone narration make videos 10x funnier. In addition to the humor, this feature improves accessibility so more viewers can enjoy the video. With the help of a free Siri voice generator, you can add voiceovers to your videos. In this article, I'll show you how to use a Siri voice generator and add the MP3 to a video.

How to Use a Siri Voice Generator

There are several Siri voice generators you can use, but in this example I opted for TTSMP3. This website is free to use, has features to customize the voice, and easy to download when you're finished. The character limit is roughly 375 words or 3000 characters and there are 28 languages to choose between. Let's jump into the tutorial.

Step One: Type your Caption

Get started by typing your caption in the white box then choose a voice from the dropdown menu. Click read to hear the voice you selected and listen to other options from the menu until you find something you prefer.

You can create a pause, emphasize words, change the speaking rate, and add a whisper effect by adding a tag to your text listed on the website.

Step Two: Download the MP3

When you're happy with the audio, click the download as MP3 button outlined in blue at the bottom right corner of the text box. Your file name will begin with the title of the website.

Step Three: Upload to Kapwing

I'm using Kapwing, a free browser-based video editor to add my voiceover to a video. You can use Kapwing on any iPhone, Android, Tablet, or PC. Head over to Kapwing and click start editing to open the studio. Drag and drop your video and MP3 into the studio or click to upload. You also can paste a video URL.

Step Four: Edit Audio and Video

Now it's time to edit the audio and video layers. If you're posting the video to TikTok set the output size to 9:16 and if you're sharing it on YouTube choose 16:9. You can add your preferred dimensions by clicking custom size. Your video and audio files will appear as separate layers on the timeline. You can zoom in or out to adjust the view of the timeline, separate a video into two parts with the split button, and trim each layer by dragging the ends.

I split my audio file with the "s" key on my keyboard to space out each sentence and dragged the layers to a new place on the timeline. If you click on a layer, you can also adjust the volume and speed. If you want to completely remove the audio from the video, right-click, select detach audio, and delete the layer.

This is optional, but you can add captions by clicking text, then change the font size, color, and style to your preferred look.  You can also add a background color and outline the text to improve its visibility.
