Cambridge voice technology company, NCT, has released an off-the-shelf hardware solution for engineers looking to remove noise and echo from communication systems. The ClearSpeech Module is a convenient and easy to use solution for customers wishing to integrate NCT’s advanced noise reduction and echo cancellation technology into their own embedded applications. Suitable applications will include wireless systems, intercom systems, voice over IP and voice recording. This ready to use hardware comes complete with a version of NCT’s ClearSpeech software installed.
The ClearSpeech Module is a fixed point dual channel platform based on the ADSP2186 DSP and AD1819 codec. It can be used for a wide range of applications including two way speech communication systems. Supplied with in-line connectors and mounting holes, the Module can be readily attached to the customer’s platform. It can be used at a basic level, supplied only with a regulated 5v power supply and line level audio inputs and outputs. However, engineers also have access to i/o that will trigger LEDs or can set various software parameters should a more dynamic and intelligent system be required.
NCT’s ClearSpeech voice technology is used in millions of mobile phones and hands-free car kits around the world and is used in the demanding environment of motor racing and even within ‘drive thru’ intercom systems. Three standard versions of ClearSpeech are available and can be chosen according to the application, offering combinations of noise cancellation, echo cancellation and signal conditioning according to the demands of the project.
The 3 Eproms that engineers can choose from are:
- Noise and Echo Cancellation for cellular and Internet telephony, conference phone and intercom applications.
- Referenced Noise Filter and Noise Cancellation for siren or alarm cancellation, surveillance and voice control of audio systems.
- Noise Cancellation, a 5 stage band pass filter and an Intelligent Squelch Filter for radio communication systems.
