To conclude this first series of posts, and before we dwell into other projects, we will write a simple program that verifies we managed to perform all steps correctly, and therefore we are capable of freely using the bridges established between Cozmo, the Voice Kit and our smartphone. In order to access the various examples which will allow us to create the first test program, we should open the "Dev terminal", which can be found on the Desktop, and navigate our way to the voice examples. (use "cd aiyprojects-raspbian/src/examples/voice" to do so). Our "Hello world" will be based on the program "assistant_library_with_local_commands_demo.py", which allows the user to create custom voice commands to be executed or interpreted by the AIY's Voice Kit. To create such new command, we should first create a string that represents the words the user should say. For instance, if we wish Cozmo to say some words when asked to, we can use the string ...
Given that Raspbian's OS is a comfortable environment to work with Python, and provided that the libraries and programs in charge of controlling both the Voice Kit and Cozmo are avaliable in the same language, it will be the one we will be using to write our scripts and future programs. But before this, it's required that we obtain the appropiated libraries for an optimal communication between the robot and our board, while verifying the kit is working accordingly. We will start off by making the adequated checks regarding this last one: According to the user manual associated to the AIY's Voice Kit, in order to check both the microphone and speaker are working fine, it will be necessary to execute the Python script "Check audio.py". After executing it from the LXTerminal, our output shows the program has been executed successfuly and, because of this, we can safely assume both peripherials are working. Next up, we need to check our Raspberry Pi'...
