Text to Speech in iSpring Suite AI allows you to convert text to speech and insert pre-prepared audio into a video project. This allows you to record an audio narration for your video on your own or produce a voice over from a text written in a foreign language.

The text-to-speech function is available only with the iSpring Suite AI subscription.

  • iSpring Suite includes a trial allowance of 10,000 characters for 30 days for one author.

  • Text-to-speech is also unavailable in the standalone iSpring Cam Pro 9 app purchased without the Suite AI package.

Only team members with the Author role can convert text to speech. Roles are assigned in the iSpring Cloud account.

Converting Text to Speech

To convert text to speech in iSpring Cam Pro:

  1. Launch iSpring Suite AI and open the Screencasts tab. Next, create a new project or open one that you created previously.



  2. Click the Audio button on the toolbar and select the Text to Speech option.



  3. In the opened window, select the language of the text you are going to convert, a speaker, and the way the voice will sound (Standard voice or Natural voice).

  4. Next, click the Preview voice button to check how the speaker sounds. 



  5. Insert the text you wish to convert to speech. The text can have up to 4,000 characters.

  6. Click the Insert button and the converted text will be added to a new track entitled "Text-to-Speech clip — Audio 1."


How the Character Limit Works

Each author has a rolling 30-day character limit.

It’s not based on calendar months — your balance updates day by day according to how many characters you used exactly 30 days earlier.

For example, if you used 2,000 characters on November 6, those 2,000 characters will be added back to your balance on December 6. (Dates may vary slightly depending on days per calendar month.)


In short, your limit replenishes gradually each day, not all at once at the start of the month.

If you run out of characters, the Text-to-Speech feature will be temporarily unavailable until your balance begins to replenish again.

The system will show the exact date when your characters will start to return.

Character Limits

30-day limit:

  • Each author in iSpring Suite AI has a limit of 1,000,000 characters over a rolling 30-day period.
  • If you’re using the trial version, you’ll have 10,000 characters for the entire trial.
     Extending the trial does not reset or renew the limit.

Per use limit: Each time you convert text to speech, you have a 4,000 character limit.

You can exceed your 30-day limit, but only for one conversion.

If you have fewer than 4,000 but 1 or more characters left in your 30-day balance, the system will still allow you to complete one full text-to-speech conversion of up to 4,000 characters.

For example, if you have only 100 characters remaining, you can still generate one conversion with up to 4,000 characters.

Editing a Text to Speech Clip

To change the text to be converted to speech, or select a different language, speaker, or voice profile:

  1. Click on the track with the text-to-speech clip and hit the Edit Text to Speech button on the toolbar. 



    The other way is to right-click on the track and select the Edit Text to Speech option.



  2. Make changes in the opened window and click Update.



  3. The text-to-speech clip in your iSpring Cam Pro project has now been updated.

  1. Let's say you made changes to the text-to-speech clip (deleted noise, for instance), and later decided to edit the text to be converted. After the text editing is done, all changes that you made previously (noise deletion) will be lost.

  2. If you made changes to the text-to-speech clip (increased the volume, for instance) and then divided the clip into multiple fragments and edited one of the fragments, the changes that you made earlier (increased volume) will be lost only in that fragment of the clip that you edited.
