Currently, Watson API supports only Brazilian Portuguese, French, Japanese, Mandarin Chinese, Modern Standard Arabic, Spanish, UK English, and US English.
It would be nice if the Dutch language will be added to supported languages.
So, all the Dutch speaking people can use IBM Watson Speech-to-text API easily instead of searching for any other options. Furthermore, this would help in automating Dutch voice to text conversion in many areas.
Looking forward for the good news on inclusion of Dutch language support.
