Introduction
Whether you are in the car, in a conference room or in your living room, you want to be able to communicate clearly without having to shout. Philips’ BeClear Speech Enhancement algorithms deliver clear voice signal even in the noisiest environments enabling you to have a natural conversation or use voice commands to interact with your devices
Based on over 20 years of experience in speech enhancement, Philips BeClear is a flexible solution that can be easily tailored to your specific application or product. In addition to the software license and application libraries, customers also receive assistance on implementing the software for their customer platform and tuning the algorithms to deliver the best performance on each device.

Mobile / Wearable
Our mobile devices let us stay connected wherever we are. Using our phones or wearables in noisy environments can still be a challenge. It can be difficult to understand the person calling and we either end up talking loudly over the background noise or having to find a quiet space to take the call.
We also increasingly use our mobile phones in speaker mode, held at arm’s length, for video calls or to let others join in on the call. And this will only increase with wearable devices such as smartwatches.
Due to their small form factor, wearable devices are also driving a growing demand for voice input and control. The devices need to be able to recognize commands reliably to be able to execute them without the user needed to repeat them several times.
Whether using voice control or making a call, the BeClear Speech Enhancement algorithm ensures clear, relaxed and effortless communication.
Smart Home
In the smart home, there is also a trend towards increased voice interaction and control of our devices. We will no longer need to search for the remote control, we can just tell the television to switch channels or play the latest episode of our favorite show.
Because of their centralized position in the Smart Home, this means that these devices need to be able to capture our voices at distances larger than 5m.
Using voice control, the BeClear Speech Enhancement algorithm ensures clear, relaxed and effortless interactions.
Automotive
We still spend a lot of time on the road. Hands-free calling enables us to stay in touch while in the car. There is also is a growing demand for using voice commands to operate the smart features in our car, from programming the GPS to making a call or changing the radio station. Voice control is much safer than fiddling with controls or trying to type in a phone number while driving.
Current voice recognition engines in in-car entertainment system work quite well when the car is not moving. But the noise in and around the car is severe and this makes it hard to recognize speech. With BeClear Speech Enhancement, voice recognition and calling in the noisy car environment are like a face to face conversation, relaxed and effortless.
Flexible building blocks
BeClear Speech Enhancement is a single algorithm that features flexible building blocks for improving the quality of captured speech.
BeClear super de-reverberation deploys a non-traditional method of removing reverberation from the signal, extending the range of Far Field communication up to 5 meters and beyond.
BeClear is the only solution currently on the market capable of full duplex, multi-channel echo cancellation.
Fast tracking beamforming continuously focuses the device’s microphones on the person speaking for superior Dynamic Noise Suppression
Dynamic Noise suppression accurately identifies and removes background noises to leave only the sound of the person speaking for clearer conversations
Smart far-end signal enhancements improve the clarity of incoming voice calls to improve the user’s experience of your product
