AudioTelligence Expands Assistive Tech Options with Earbud Assistive Listening Case

British company AudioTelligence has announced a new product concept which integrates assistive listening technology into an earbud charging case. Following previous approaches in this direction, with dedicated microphone devices and smartphone integrations, the company is now offering a more attractive option for manufacturers and consumers. The combination of hearing technology with earbud charging provides manufacturers with a comprehensive all-in-one solution for individuals with hearing impairments as well as for anyone who needs to hear clearly in noise.

AudioTelligence launched Orsana, a demonstration device of an assistive listening solution to help users hear clearly in noisy environments, with hearing aids or consumer TWS earbuds. Orsana connects wirelessly to Bluetooth LE Audio enabled earbuds or hearing aids – and can be used by up to 6 people at the same time. The device is available for hearing aid and consumer electronics companies interested in implementing their own assisted listening solutions.

Consumers are increasingly looking to have high quality sound integrated into their lives in creative ways. However, ensuring that their demands are met across connectivity and sound can be hard to achieve. Often, the more creative and interesting the application, the higher chance it’s harder to produce a sound that is perfect for every use case.

Cambridge audio software specialist AudioTelligence has announced the launch of Aiso, a new consumer technology and family of products for smartphones based on its proven blind source separation audio technology. The company's approach allows removing any voice interrupting a smartphone video recording or call in real time, without losing what the main speaker is saying. The software-only solution is available for licensing for Android smartphones.
