Bose demonstrates noise-free phone calls from car cabins

Bose used CES 2018 to show off its ClearVoice technology, which creates noise-free phone calls.


In Bose’s[1] exhibition space at CES[2] 2018, the audio company presented a solution to a consistent problem in cars: background noise interfering with phone calls. Bose’s ClearVoice technology delivered clear, noise-free communication to both participants in a conversation. ClearVoice makes use of Bose’s noise canceling expertise, which many people experience using the company’s headphones, and its headrest speakers.

In the demonstration, a Bose spokesman sat in a Nissan[3] Micra modified with the technology. With music[4] playing over the stereo and voice prompts from the navigation system cropping up, he tried to use voice recognition on an iPhone[5] to send a text message. The result was extremely garbled due to all the other noise.

Turning on ClearVoice, he repeated the exercise, showing how Siri picked up each word, translating it correctly in text. Initiating a voice call to a partner in another room, the background noise seemed to fade away as the callers’ voices came clearly through the headrest speakers. More impressively, the background noise was also canceled out for the other participant in the call.

Sitting outside of the car, that Bose spokesman accepted a call coming the person in the car. Without ClearVoice, the caller from the car was very difficult to hear due to the music and other background noise. Turning on ClearVoice in the car made the caller’s voice much more intelligible.

Along with Bose’s digital signal processing technology, which can differentiate voices from music and other noise, ClearVoice relies on an array of four microphones.

A Bose spokesman said ClearVoice was still in the early concept stage, but if automakers adopt it, we might hear fewer people yelling into their phones[6], trying to be heard.
