What Will You Do?

The Voice Command Audio Collection Project focuses on collecting natural speech data to support the development of advanced voice-controlled technologies.

This is a short project which includes one task that consists of recording several sentences in different environments with noise where the speech is still audible. The environment could be walking on the street, or passenger in a moving vehicle, or in a busy restaurant/café, or in a room with a TV playing.

The task can be carried out using either an Android or IOS mobile device.

The process is supported through detailed project manuals, with optional kick-off sessions available to provide clarification and assistance on technical and procedural aspects.

All tasks are remote, performed through an online platform available 24/7.

This opportunity is offered for freelancers under a commercial contract.
