Use Case:
Voice Recognition for Robotics
Description
Robots and autonomous systems in household, industrial, educational settings that can be reliably controlled using voice commands and/or encourage human-robot interactions with natural language conversation. 360° listening capability that can be controlled with voice commands.
Challenges
- Noises in the background
- Household background noises including HVAC system, background
music/TV, people conversing, kitchen cooking - Industrial, warehouse, and commercial noises from machinery and processes
- Household background noises including HVAC system, background
- Distance
- Recognize voice commands from distances of 0.5 to 9 meters
- Non-line-of-sight talker source
- Summoning / commanding a robot that is not in the same space
- Talker not looking at the robot when commanding
- Large reverberant spaces
- Factories and warehouses are large spaces that cause sound to bounce back and forth, resulting in strong reverberation and the commanding voice arriving from multiple directions
Solution Proposed
ArkX EveryWord™ AFE:
- Audio Front End supports
- Multi-mic noise reduction removes stationary and transient background noise
- Up to 9 meters 360° voice operating capability, automatic gain controls (AGC) for uniform loudness throughout the distance range
- AFE algorithm exploits reverberant propagation to better identify and separate noise from desired speech, and to capture desired speech from around corners / non-line-of-sight talker
- De-reverberation processing enhances the intelligibility of speech in large spaces
- Local commands enable voice control when cloud-based voice recognition is unavailable/undesirable
- Low power consumption
Far-field Voice Applications
Our voice capture technology can easily be applied to a wide range of voice-enabled smart products and devices.
