DEVICE CONTROL DATABASE
The use of voice control in mobile and embedded devices, from PDAs and
phones to automotive systems has become increasingly important.
Business awareness of the possibilities offered by this technology,
and ever growing legislation restricting the use of mobile equipment,
is driving this market forward. As the technology makes the
transition from professional users to consumers, high recognition
accuracy is paramount for any product to gain widespread penetration.
Collected by 20/20 Speech Limited, the Device Control Database
consists of over 17 hours of high-quality recordings from 47
UK-English speakers covering a range of possible applications for
controlling PDAs and other small or embedded devices. The data was
recorded using the internal microphone of a Compaq� iPAQ�. This was
selected as representative of the type of microphone and packaging
typically associated which such PDA and embedded systems.
