Speed up course development by converting text to speech right in Storyline 360. For example, use the text-to-speech feature to quickly narrate a course for stakeholder review or to localize narration in different languages. You can even choose the voice and language to make sure every word sounds right.
Watch this video demonstration, then check out the detailed instructions below.
- Converting Text to Speech
- Updating Text-to-Speech Narration with Script Changes or a Different Voice
- Generating Closed Captions for Text-to-Speech Narration
- Replacing Text-to-Speech Narration with Recorded Narration
- Go to the Insert tab on the Storyline ribbon, click the Audio drop-down arrow, and choose Text-to-Speech.
- When the Insert Text-to-Speech window appears, select a Language from the first drop-down list. This ensures that your words are spoken with the correct pronunciations.
- Then choose a Voice from the second drop-down list. You can hear what a voice sounds like by clicking the Preview Voice button next to the list.
- Type or paste your script into the text-entry field. Or, if you want to use your slide notes as your script, just click the Copy from Slide Notes button.
You can convert up to 10,000 characters at a time. If your script is longer than that, break it into smaller chunks and generate more than one text-to-speech audio clip. Then place the audio clips back to back on the timeline so they play in sequential order.
See below for tips on pronunciation and phrasing.
- If you’d like to add closed captions to your text-to-speech narration, mark the Generate Closed Captions box in the upper right corner. Learn more about text-to-speech closed captions below.
- Click Insert to complete the process. You must have an internet connection to convert text to speech. If you're offline, Storyline will prompt you to connect to the internet and try again.
Storyline will convert your text to narration, and it’ll appear as an audio clip on the slide’s timeline. The conversion process is fast, but lengthy scripts will take longer to convert.
You can add as many text-to-speech clips as you want. You can even use different voices for different clips, which is great when you want to create a scene where two or more characters are having a conversation.
Tips for Controlling Pronunciation and Phrasing:
What if you convert text to speech and then need to update it with script changes? Or what if you want to switch to a different voice later? No problem. Storyline makes it easy to update text-to-speech narration.
- Right-click your text-to-speech audio track on the slide’s timeline and choose Text-to-Speech from the context menu that appears. Or, select your text-to-speech audio track, go to the Options tab on the ribbon, and click Text-to-Speech.
- The Insert Text-to-Speech window will open with your original script. Edit the script as needed or choose a different voice—or both.
- Click Update.
Storyline 360 can generate closed captions that are automatically synchronized with text-to-speech narration, making your course more accessible.
You can add closed captions at the same time you convert text to speech or add them later. Here’s how.
