Use Case:
Voice Recognition for Portable Conference Speakerphones
Description
Conference speakerphone with clear 360° voice capture for up to 12 people without the need to use any extension microphones. Built-in versatile connectivity to laptops/PCs/mobile phones/tablets via USB and Bluetooth. Powered by USB and built-in rechargeable lithium ion battery for portable and travel uses.
Challenges
- Noises in the background
- HVAC system, chatter outside the meeting space, background music/TV
- Echo heard at the far-end
- Voice coming through the speakerphone’s speaker gets picked up by the microphones and being transmitted back to the far-end
- Half Duplex
- Only one person can speak at a time, the other person’s speech gets cut out
- Distance
- Typical distances for meetings could be 1 to 9 meters
- Bad sound quality
- Muffled, reverberative (“inside a tunnel”) speech
- Other end of the call cannot easily understand the talker
- Development
- Aggressive schedule
- Avoid a complete board spin
Solution Proposed
- ArkX Technology
- Works extremely well even in obstructed voice path
- Captures voice from up to 9 meters in very noisy environments
- Features solder-on “module” allowing easy integration onto existing board
- Utilizes 12 AEC’s to ID, classify and suppress speech originating from TV, audio devices and other extraneous environmental noises
- Amazon pre-qualified speeds time to market and reduces development risks
- Supports Google, Amazon, Baidu and other platforms
Far-field Voice Applications
Our voice capture technology can easily be applied to a wide range of voice-enabled smart products and devices.
