Hello!

Use SSML tags in your text to control speech rate and other speech attributes.

Please refer to this convenient demo for experimenting with SSML tags - 

https://sitepal.com/documentation/fine_tuning

And try the following text sample - 

This is normal speech <prosody rate="slow"> this is speaking slowly </prosody> <prosody rate="fast"> this is speaking fast </prosody> back to normal.
Let's try more precise control. First, let's use relative values:
This is normal speech <prosody rate="-30%"> this is speaking slowly </prosody> <prosody rate="+40%"> this is speaking fast </prosody> back to normal.
Now absolute values:
This is normal speech <prosody rate="60%"> this is speaking slowly </prosody> <prosody rate="140%"> this is speaking fast </prosody> back to normal.

Notes: 

* different voices may interpret tags differently - so best to experiment and identify what works best with the voice of your choice. Specifically - some voices may work well with relative values, others with absolute values.

* certain voices do not support SSML tags at all - and are thus not included in this "fine tuning" demo. If a voice is not available in the demo, that would be the reason. Specifically - all engine 2 and engine 4 voices do not support SSML tags.

Hope this helps, best,

Our avatars work on all modern browsers on Windows, Mac, iOS and Android.

We regularly and extensively test all avatar functionality across the board, including all API functions.

As browsers evolve - we continuously adapt our APIs to support updates and changes. Because SitePal is a cloud based solution - this process is for the most part transparent to our clients. 

By "all modern browsers" - I am referring to Chrome, Firefox, MS Edge, Safari.

Opera is not officially supported, but I believe it works.

IE11 is still supported, but will be deprecated probably later this year as its penetration dips under 1%.

Hope this helps,

best,

Gil
