headofrock,
Some of the sites using the speak2web plugins are packleaderbehavior.com speak2web.com weirdandwildpizza.com simonsvoicemarket.com and cuttingedgegamer.com
If you can speak Greek then also look at zeotecgroup.com
— I am currently looking at methods to autodetect site language changes and transition appropriately to improve compatibility for this client.
Let me know if you’d like to discuss.
