Problem

Low recognition rate

Small distance (30cm)

Susceptibility

Teach-in required

Monolingual

Uneconomical

Solution

High recogntion rate

The module offers the highest detection rates even in demanding applications such as echo and background noise in the operating room.

Multilingual

More than 14 languages are available for the module factory-fitted. 

Economicaly

The modules are very compact despite completely self-sufficient functionality and can be integrated into almost any PCB. With long-term availability.

Far-field up to 16m

Up to a range of 16m, commands with a high recognition rate can be detected and processed.

Speaker independent

No teach-in necessary.

100% Offline functionality

The modules are completely self-sufficient and do not require an Internet connection to develop their full functionality.

Hybrid Function

1. Voice Control Modul

The voice control module is very compact, the microphones can be positioned according to the customer’s wishes, is optimized at maximum cost, the direction can be fixed via a beam width and contains the following speech control functions. 

A speaker independent wake-up word is used to activate the voice control module.

A personalized wake-up word can be trained and is used to activate the voice control module.

A secure wake-up word can be trained and  is used to activate the voice control module. For example to get acess to an house door.

Natural speech recognizes the context in an unlimited number of different sentences. For example, turn on the light, it’s too dark here, please make it brighter here, turn on the lamp, etc. Here the possibilities of variations are unlimited.

After the wake-up word commands are detected and then can be controlled via an interface USART, SPI, GPIO, etc. and / or voice outputs are performed. 

The offline assistant can store and play audio data. Then the module is able to answer.

2. Audio Front End

The module also work as a hybrid function, so no voice control solution from DW Embedded needs to be used, only the prefiltered voice signal can be used via USB or I2S.
