ResponsiveVoice gets you an all-in-one, affordable and pain-free solution to integrate text to speech with a American accent, one that only weighs 14kB and solves the myriad problems speech synthesis entails, which include (but unfortunately are not limited to) per-character costs, having to initialise the speech engine after page load, timing delays between API calls, speech rate problems, it’s a mess we chose to tidy up so you don’t have to!

Voice quality

female head

The main voice is female (“US English Female”), and is supported in Chrome for desktop,  OSX Safari, and iOS Chrome and Safari. Rating: 10/10 

female head

The fallback voice is also female, and is used in the Android default browser, Internet Explorer, Firefox, and Opera. Rating: 10/10

The two voices sound very similar, so that users can have a consistent experience on platforms that are officially supported, but also  on those that are not.


Accessibility is a phenomenon that is here to stay. Everyone should benefit from unhindered access to online content, and this is why the Department of Justice decided to include online content in the ADA, making it illegal for many websites and apps to include barriers in their design.

ResponsiveVoice can help crush a few of these barriers by giving complete and unrestricted access to your content to people with a variety of disabilities and impairment, ranging from print disability to quadriplegia. At LearnBrite HQ we are committed to help make the internet accessible to all by creating reliable technology that anyone can use.

Ease of use

From our one-line-of-code integration to the extensive support we give to our customers through documentation and direct contact, we want to give you the best possible experience, and save you the headache that is getting into text to speech. We offer many different services, including (and not limited to!) a message editor, end-of-page messages, direct, welcome and even timed messages, deep integration with Chat Mapper and other authoring and e-learning tools, and much more.
