Ultra Wide Band (UWB)
Why UWB
Ultra-wideband (UWB) is a wireless communication protocol that transmits Radio Frequency pulse signals between devices. It can precisely determine a device's relative location by measuring how long it takes for a radio pulse to travel between the devices. Unlike Bluetooth and Wi-Fi, it operates at much higher frequencies with much wider bandwidth, the frequency range of Ultra-wideband is between 3.1 and 10.6 GHz that allows it to emit up to 1 billion pulses per second to make it capable of capturing real-time and accurate spatial and directional data. Its distance measurement can achieve up to 10cm accuracy and nano seconds measurements.
Speaker ID (dVector)
Why Speaker ID
Biometric authentication has gained lots of momentum in recent years due to the demand for safety and security in cyberspace. Fingerprint identification and face recognition are two of the popular biometrics that are used. However, both methods require the user to either touch or stay close to sensors and pause what they are doing. Voice ID, on the other hand, is as unique and individualistic as fingerprint and face and can also be used for biometric identification. It automatically recognizes who is speaking by identifying the individual information included in their speech waves. Speaker recognition can usually be categorized into text dependent speaker recognition and text independent speaker recognition.
Text independent Voice ID is more flexible as the user can speak anything and the system can still recognize it. Speaker verification system usually is composed of two major components. The enrollment component and the verification component. Enrollment component extracts the voice feature of all speakers who need to be verified and creates a speaker reference model and stores it in a database. The verification component compares the test reference model of the to-be-verified speaker with the reference model stored in the database to identify if there is a match or not.
