Have a conversation with your robot using your voice by navigating through menu options so your robot can perform tasks. This is similar to how menu trees on phone systems work. You can define the menu tree in the configuration to run scripts based on options selected by the user with their voice. The menu tree can have as many branches as necessary. The robot will speak each menu prompt and then optionally speak each option to the user. The microphone on the robot or PC is used for the users...

This ARC skill uses the default recording device (i.e. microphone) configured on the Windows PC to detect frequencies. The identified frequency can be assigned to a variable and move servos. A range can be specified to limit the servo movements between Min and Max frequencies. The type of algorithm used to detect the frequency is called Fast Fourier transform, or FFT for short. Detecting multiple frequencies is heard as noise, which will produce bumpy responses in the data log. Ideally, a single...

The Sound movement skill is for embedded devices on your robot that have two integrated microphones for the left and right channels. This skill will allow your robot to respond to which side the sound is coming from. A script can be applied to each direction of the sound to control movement. *note: not all computers have stereo microphones or stereo microphone inputs. Verify that your computer mic input is stereo, otherwise this robot skill will receive mono audio. Main Window 1. Left...

Execute a script when sound is played out of the EZB speaker. This robot skill will also set 3 variables for the sound level that your script loop can access. The variables include Min Level, Max Level, and Average Level. Because the script is executed once when audio is started to play, it is advised that your on-going script is contained within a loop. Once the audio has stopped playing, the script will cancel and therefore stop running your loop. *Note: To avoid infinite recursive run-away...

If your robot has servos connected to simulate a mouth, this skill will move those servos while speaking. If the robot skill that is speaking is not using the built-in Say() commands (such as the Azure Text To...

AKA the worst speech recognizer - by request of users who wish for unusable open dictionary offline speech recognition. Unlike the regular speech recognition control which allows pre-defined phrases or the Bing Speech Recognition which works, this is an open dictionary, allowing any combination of words. However, the implementation of this type of speech recognition is not great... not great at all! You can get acceptable results sometimes by using a handheld microphone and very well trained...

Voice Activity Detection (VAD) detects the presence or absence of human speech. This uses an advanced algorithm to detect human voice in the microphone input of the PCs default audio device. When a human voice is detected or lost, a respective script will run. Voice Detected When voice is detected, the graph will display in green and the voice start script will execute. Voice Not Detected The display will be red when there is an absence of a human voice and the voice end script will execute.
