Page 10: How It Works
7. How It Works? What gives the SpeakUp its speech recognition capabilities is the firmware we developed for the on-board MCU. It’s based on the DTW algorithm, which makes it decisive, it turns your talk into action almost instantly. Sound is received through an on-board microphone. There’s also a 3.5mm jack for Input: connecting an external microphone. -
Page 11: Speakup Firwmware Algorithm
The feature vectors extracted from speech signal are required to best represent the speech data, to be in size that can be processed efficiently, and to have distinct characteristics. The SpeakUp Firmware uses Dynamic Time Warping (DTW) algorithm - word-based, isolated word, speaker dependent and template matching algorithm :... -

Page 20: Assigning An Action
8.6. Assigning An Action When a new command is recorded, it is time to assign it an action. The action will be performed when the voice command is recognized. Also, a 16-bit index number of the voice command will be sent via chosen communication interface (UART or USB) . There are five types of action that can be assigned : NONE: When this option is selected, no action will be performed on the corresponding GPIO pin upon voice command matching. - Page 21 Pulse parameters The pulse parameters can be set in the Pulse Parameters window (click on the Edit pulse parameters icon Edit pulse parameters to open it) : A period (T) is the time it takes for a signal to complete a single cycle (sum of the high state and low state time periods).

9. Direct Configuration You can perform some basic configuration directly on the SpeakUp without using the software. Different combinations of button presses will allow you to record, re-record or erase commands. You’ll get feedback from the on-board LEDs. However you won’t be able to assign specific actions with this method. -
