It’s time for change… Welcome to Alango’s new web site!


We tried to make our new site more inviting and informative and easier to use.

We still have some white spots but decided to switch immediately.

Our old website ( will continue to be accessible
until all materials have been relocated here. You can find a temporary link
to our old site at the bottom of all these new pages.

We’ll appreciate your comments and suggestions. You feedback is very important to us.
Please, write to

Sincerely yours
Alango team

Engine, road, wind and rain noise have a distinct adverse affect on speech recognition efficacy. Alango does not make the speech recognition system but our enhancement technology dramatically improves the voice recognition capture rate especially in low signal to noise environments.

Block Diagram



Acoustic Echo Canceller (AEC) Eliminates stereo echo of voice prompts or music being played by the car stereo system in each microphone signal. Acoustic echo canceller allow the system to respond to the user’s voice during music playback or barge-in.
Adaptive Microphone Array A microphone array utilizing a proprietary adaptive beamforming technology that preserves the speech from ambient noise and detects the direction of the voice commands.
Noise Suppressor (NS) Detects and attenuates stationary and transient noises.



Flexible implementation of optimal voice pick up and transmission to the ASR according to the cabin and number of microphones. 

Optimal usage of available resources.

Portable to all major computational platforms.
