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 (www.old.alango.com) 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 webmaster@alango.com.

Sincerely yours
Alango team

Introduction
 

Smart Home Devices can be used for many different applications such as assisting with daily tasks in the home and office.  Many of these applications will rely on far-field voice recognition technology. Therefore, the performance is dictated by the ability of the device to distinguish between the user’s voice, sound played by the device speaker (echo) and ambient noise.  Alango is focused on the critical link in this chain - where human meets machine.  Alango’s Voice Enhancement Package (VEP) dramatically improves the devices far-field voice pick-up through the implementation of software algorithms that utilize a microphone array to discriminate against noise and home in on the user’s voice.

Definitions
 
N-Mic Beamformer A microphone array utilizing adaptive beamforming preserves the speech from ambient noises, enhances speech from specified directions and helps detecting the direction of voice commands.
Acoustic Echo Canceller (AEC) Eliminates acoustic echo from the loudspeaker to the microphones. Both mono and stereo acoustic echo cancellers are available.
Noise Suppressor (NS) Detects and attenuates stationary and transient noises.

 

Benefits
 

Flexible implementation of optimal voice pick up for voice trigger recognition, local (embedded ASR) or transmission to cloud for different environments and number of microphones.

Relatively low computational complexity.

Availability on all major MCU and DSP platforms.
