I would like to use TTS.
So I followed https://www.webosose.org/docs/reference/ls2-api/com-webos-service-tts/ to run the service.
There is an error as below.
So I followed the error output part while looking at the "com.webos.service.tss" source code, and there was one of several clues.
Errors can be output when there is no language for TTS.
So, as in the picture below, I checked the list of languages currently available through the command and found nothing available.
Can you tell me how to solve it?
