WOW! How about this! This is no simple thing. Lot's of work went into this. Thanks!!


Thanks Dave !

Before it was a single Watson plugin supporting multiple services: Speech To Text Text To Speech Visual Recognition Assistant Language Translator

It was too big and a little difficult to maintain, so I split in multiple service plugins and I'm fixing/releasing one by one.

The big one became the: Watson Speech To Text

ControlCommand under javascript doesn't work even though it is on menu for selected items.

Example: ControlCommand("Watson Speech To Text", StartListening);

in Javascript gets error StartLisening not defined Start Stop etc all get the same error

You need to modify the auto menu generated command to put quotations around StartListening ControlCommand("Watson Speech To Text", "StartListening");

In EZ-Script this works fine ControlCommand("Watson Speech To Text", StartListening)

I think ARC will need an update to fix this until then if using the auto ControlCommand menu to generate Javascript remember to add quotes.


Arc doesn’t need an update - the robot skill needs the update. Arc’s compilers can’t guess when a quote is needed or not :)

My solution is put your own quotes around the word/string. All strings need quotes.
