What is the Developer API?

The Developer API is a collection of functions you can call to add text-to-speech to your website.

Is it for me?

If the text-to-speech functionality you look for is not available through the WordPress plugin or the ResponsiveVoice Agent, the API is for you and will make building it a snap.

How do I install and use it?

Including the API is easy, you just need to include the ResponsiveVoice JS file in the <head> of the pages you want to use ResponsiveVoice in.


After that, you’ll be able to call ResponsiveVoice like any other library. You can find a list and a description of calls available here: http://responsivevoice.org/api/

What license do I need?

The ResponsiveVoice API has two licenses available: the Website API can only be used in static websites, which do not have user-related information or interactions (such as a user system), and do not sell products or services. Other websites will require a Developer API license. You can find more details on the Pricing page.

Additionally, non-commercial, not-for-profit websites (which does not include ad-supported websites) can use ResponsiveVoice completely for free by including the ResponsiveVoice logo and a link to https://www.responsivevoice.com in the relevant pages (more information on that here).

Awesome! Where can I try this?

You can try the full-featured ResponsiveVoice API for a month, start here!
