FEATURES
INTELLISONIC
The intelligibility and use of mobile communications
are often impeded by the impact of noise from the
immediate environment. IntelliSonic is a software-based
speech enhancement technology that when coupled
with Knowles’ microphones, reduces the effects of
reverberation, directionally interfering speech,
background noise and annoying acoustic echo.
COMPLETE SOLUTION
When you consider the interdependency of microphone design, acoustic porting, and sound signal conditioning, it's easy to see why Knowles
Acoustics has taken an integrated approach to your acoustic system needs.
• Noise suppression 16 dB
• Interference cancellation via beam-forming array 30dB
• Acoustic echo cancellation 27dB
• Speech bandwidth 8kHz
APPLICATIONS
Platforms such as tablets, laptops, ultra-mobile personal computers (UPCs), and other mobile computing devices have a number of applications that
would benefit from IntelliSonic to enhance the user experience and final product perception.
• VoIP Telephony
• Command and Control
• Voice recognition
• Dictation
