I have written the code for the mixing of throttle and turn channels during the weekend and tested it yesterday.
The voice comand control solution has been tested in the rover.
Control is quite responsive, now the only issue seems to be the microphone sensitivity to nearby noises.
Unfortunately, what is 100% in a quiet room that is not as good in the open area.
Check the vid:
Soon I will try to change the stock mic into some noise canceling one.
Hopefully that will improve the recognition up to 100%.
Apart from this minor technical issue I am satisfied with the result.
Soon I shall build in some more words for controlling smoothness of throttle and steering.
Then the next step is to mount the fpv gear and go outside and test everything working at distances of more hundreds of meters.
