Getting Punctuation from Google Speech-to-text

[nuttyartist]

By default, Speech-to-Text does not include punctuation marks in the results from speech recognition. We can, however, request that Speech-to-Text detect and insert punctuation in transcription results. Speech-to-Text can recognize commas, question marks, and periods in transcription requests.

This can be enabled by setting the enableAutomaticPunctuation field to true in the RecognitionConfig parameters for the request.

This is what I did in speechtotext.cpp:

recognition_config->enable_automatic_punctuation(); 

But it doesn't seem to work. I also made sure to have the latest googleapi from https://github.com/googleapis/googleapis.
