ALADIN

Duration: 2011 – 2014

Project Description:

usertest

For people with a physical impairment, using switches and buttons to control everyday technology and devices is not always easy. Although voice control could be a viable solution, vocal interfaces for so-called ‘assistive devices’ are not yet widely implemented – because of several reasons:

  • Users that could benefit from voice control often have a speech pathology as well, making (even state-of-the-art) speech recognizers virtually useless.
  • A user’s voice may change over time due to progressive speech impairments, the environment, changing body position, etc. – requiring the voice control solution to adapt / learn ‘spontaneously’ for the system to work properly.

The ALADIN (Adaptation and Learning for Assistive Domestic Vocal Interfaces) project addresses current solutions’ shortcomings, thus making voice control a viable aid. The ALADIN interface is capable of learning what is the meaning of a certain command, which words are used, and what are the user’s vocal characteristics. This gives users much more flexibility, and helps them overcome current limitations: they can formulate commands as they like, using the words they are able to pronounce. The commands are learned while users are using the device.
