The Sugar Automatic Speech Recognition (ASR) module is specially designed for schools and can be used offline. The length and width of the module are both of 5 Lego units. The 4 holes at the corners allow compatibility with building bricks and the installation of M4 screws.
This module comes with a built-in speaker which makes speech recognition possible within 5 meters.
The standard PH2.0 4PIN serial port in the Kittenbot system is adopted in this module to communicate with the mainboard.
It supports 3.3V~5V power supply; with the external battery port, it also supports the lithium battery power supply from 3.7V to 4.2V.
The built-in bi-colour (red &green) LED indicates the condition of the module.
A Sugar LED module can be connected to this module through a PH2.0 3PIN port to be turned on and off.
A standard 2P 2.54 port can be used to control the on and off and the speed of a motor.
A 3P 2.54 port can be used to control a servo to turn from a certain angle to another.
This ASR module also performs simple broadcasts with content like time, weather, and date.

Features
- Standalone AI function
There is a port on this module specially designed for an external lithium battery power supply. There are also a built-in bi-colour LED, an external Sugar LED port, a motor port and a servo port.
Even without connecting to a mainboard, the ASR module itself is able to perform some basic AI functions like the voice-activated light, voice-activated fan, voice-activated door, voice-activated window and voice-activated robot car.
- Speech Recognition & Speech Synthesis
Connecting to a mainboard, this module is able to broadcast numbers, time, date, etc.
- Visual Programming Platform
This module can be programmed with the Scratch-based programming platform Kittenblock. Built-in speech recognition and synthesis blocks can be found on this platform directly.
- Compatible with LEGO Bricks
Like other modules in the Sugar Series, the length and width of this module are both of 5 Lego units. LEGO bricks can be conveniently inserted into this module.
- Built-in High-sensitivity Microphone & Speaker
With no need to connect to an external microphone or speaker, students can focus more on learning programming. Speech recognition within 5 meters can be realized with the voltage of 5V; the speaker is tiny and loud.
