1. Introduction

The SpeakUp is a speaker dependent speech

recognition click board with standalone

capabilities. You can set it up to recognize over

200 voice commands and have the onboard

STM32F415RG MCU carry them out. It works

by matching sounds with pre-recorded

commands. Sound is received through an

onboard microphone and then processed by

a VS1053 IC with a built in stereo-audio

codec. The SpeakUp comes with

a dedicated software tool for

easy configuration. The board is

lined with 12 user programmable GPIOs

for standalone functionality. It also carries a

standard mikroBUS™host socket.

2. Applications

Wouldn't you rather issue verbal commands and have your machines comply, instead of pressing keys, pushing buttons and flipping

switches all the time? There's a wide range of applications for the SpeakUp.

Command your lights, doors and home appliances.

Create voice commanded remotes for TVs or media centers.

Reduce complexity and cost of control interfaces.

When doing something with both hands and voice command is the only option.

4. How To Use It?

Before using your click™board on your target platform, make sure to solder 1x8 male headers to both left and right side of the board.

Two 1x8 male headers are included with the board in the package.

Turn the board upside down so that

the bottom side is facing you upwards.

Place shorter pins of the header into

the appropriate soldering pads. Turn the

board upward again. Make sure to align the

headers so that they are perpendicular to

the board, then solder the pins carefully.

Now you need to train your SpeakUp to

obey your commands. Plug in the board

to your PC through USB cable. Configure

it using the free software (see page 12).

Alternatively you can configure the board

directly using the on-board buttons (see

page 24).

1. Prepare it 2. Configure it

The SpeakUp now understands your

commands. Connect relays, motors or

other electronic actuators directly to

SpeakUp’s GPIO pins. Alternatively plug

the SpeakUp into any board or shield

carrying a mikroBUS™socket. You can now

control your devices with your voice.

5. Tech Specs

Along with its key components, the SpeakUp packs other useful bits like two buttons for recording or deleting voice commands manually, while

three signal LEDs give recognition feedback and indicate power.

7. How It Works?

Input:

Output:

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

connecting an external microphone.

After the processed sound has been forwarded to the STM32F415RG MCU that interprets the voice

command, there are two output options which can be utilized at the same time or separately:

STANDALONE MODE:

On-board MCU directly controls

external devices using 12 user

programmable GPIOs

CLICK™MODE:

Sends index of the matched voice

command to a selectable interface:

USB or UART.

Between the mic and the MCU sits a VS1053 IC with a

built in stereo audio codec to process the raw signal.
