We believe that only the technical perfection of speech recognition
technology may guarantee the success of speech interface
implementation. MicroAsr's large vocabulary continuous speaker independent
speech recognition technology allows for the creation of a real, natural man-machine
interface. It's on-device technology. MicroAsr's software doesn't need an
internet connection to add a speech recognition interface to your device.

MicroAsr's solution allows the manufacturer to add a voice control even to a low-cost system. It operates at STM32F7(F4) and other MCUs with a performance of 200DMIPS. Our on-device solution doesn't use any internet connection.
You can easily add and change voice commands on the device in real-time depending on your needs in the moment.
Speech recognition grammar for the coffee machine can be visualized in the figure below.
For example, to control coffee maker you can use voice commands such as:
- May I have a double-shot cappuccino with cream
- I'd like a single-shot espresso with milk
- Make me a americano
- I want a triple-shot espresso
- Can I have a latte with cream
- I want a double-shot Mocha
- ... etc
MicroAsr offers the development of customized state-of-the-art speaker-independent speech interfaces and licenses its speech recognition engine working at the edge.
MicroAsr's on-device Speech SDK is compatible with a wide range of modern MCUs. Due to its highly optimized algorithms, MicroAsr's SDK supports IP cores with a performance of 200 DMIPS.
