Using text-to-speech (TTS) is a great option when you can’t add professional narration to your courses. Simply type up a script, and the system will automatically generate audio clips based on that text. You can pick the language and gender of the voice, as well as choose from different voices to find the one you like best.

If you haven’t worked with TTS before, you might be wondering which situations or contexts are well-suited for TTS. Here are a few examples:


TTS is a helpful feature to use during the storyboarding phase. It’s an easy and effective way to add audio to your storyboard, allowing stakeholders to get a sense of how it will sound and what will be covered in it. It’s also a good time to assess whether you need to tweak the script and specific verbiage used in the TTS. If you’re planning to do your own narration, you can use TTS as a placeholder until you’re ready to do your own, final recordings.

Adding Narration

If you don’t have a real person or voice actor to record audio for your e-learning, the TTS can be a great fill-in. It adds a different form of multimedia to your content and allows you to shift away from having a text-heavy course.

Increasing Accessibility

TTS is an important tool for increasing accessibility. If you have learners with any type of visual impairment, they might have trouble reading text that appears on-screen. Having the ability to turn on an audio recording of the text that appears in your course will make your content more accessible.

Simplifying Content Maintenance

If you’ve ever had to maintain a course with narration, you know it comes with many challenges. Having to re-record entire audio clips because of one small word change and matching up recording quality for clips recorded at different times can be a nightmare. With TTS, there’s no need to re-record; simply update the text and the audio caption is re-generated. Quick and painless!
