This example shows how to use the SpeakUp Click board with a multimeter acting as a display to show the results of the voice commands.
There is an accompanying 10.5 minute long step-by-step video tutorial that shows how to create this project from the beginning: SpeakUp Multimeter Video Tutorial
This is the SpeakUp Click Board with the mikroBus connector and JTAG connector soldered in place.
Step 1. Install the SpeakUp Utility that is found partway down on the SpeakUp product page.
Step 2. Open the Multimeter.spk example file in the SpeakUp Utility.
Step 3. Plug you SpeakUp Click board into your desktop PC's USB port.
Step 4. Switch to each tab in the SpeakUp Utility. Click the edit icon and re-record the voice commands for "Port On", "Port Off", and "Half Duty" using a relaxed tone of speaking.
Step 5. Save the SpeakUp project again, and upload your modified voice commands to the board.
Step 6. Connect your digital multimeter probes to the SpeakUp click board using a set of test clips. The multimeter should be used in DC Volts mode. The red lead on your meter connects to the IO 1 pin, and the black lead on your meter connects to the GND ground pin.
Step 7. Power the SpeakUp click using an external USB wall power supply and let it check the room for ambient noise for the first 10 seconds.
Step 8. You are now ready to try out the voice recognition module.
When you say "Port On" the multimeter should read 3 volts. This sets the IO 1 pin to on.
When you say "Port Off" the multimeter should read 0 volts. This sets the IO 1 pin to off.
When you say "Half Duty" the multimeter should read approximately 1.5 volts. This mode is created with the SpeakUp Utility's Pulse action set to a 50% duty ratio.
