Adding Welsh to Annyang - help!

[BiblioVee]

Hello,

I work at a Welsh university and we would like to get web speech recognition in Welsh working on browsers so that we can switch on a feature in our Library Management System that enables our users to search for items on our catalogue by voice search.

At the moment, the web speech works really well in English. However, it doesn't recognise anything when you try voice searching in Welsh and the search results are a complete miss!

We've been pointed to Annyang as a possible solution. Looking at supported languages, it doesn't have Welsh in the list.
Is there a way to add Welsh in?

Grateful of any advice.

Thank you for your help.

Best regards,
Vicky
