KOPIN CORPORATION LAUNCHES WHISPER VOICE CHIP.
Kopin Corporation has launched its Whisper Voice Chip. Designed to enhance the performance of existing audio systems and speech recognition engines, the Whisper chip allows the speaker's voice to be clearly heard by the listener, whether a person or a machine -- even in extreme noise environments. The Whisper chip incorporates Kopin's Voice Extraction Technology that enables a truly hands-free voice interface.
At the heart of the Whisper Chip is Kopin's proprietary Voice Extraction Filter (VEF) technology. VEF is a patented approach to singulating the voice signal without distorting it. It allows the user to speak in a low or normal voice, even in very noisy environments, and be clearly heard. There is no need to raise your voice. VEF was developed, tested and refined in products designed for high noise military and industrial settings over several years and provides a dramatic improvement in the performance of speech recognition systems when compared to the traditional methods of noise cancelation in use today.
The accompanying chart compares the performance of smart glasses with the Whisper chip against the automatic speech recognition (ASR) and noise cancellation technologies found in two popular devices: a leading Bluetooth earphone and a leading smart phone. While the Whisper chip's performance remains consistent as noise levels increase, the earphone's performance begins degrading at 75 decibels (the amount of noise associated with a car interior or dishwasher) while the smart phone's ASR performance starts to drop at approximately 85 decibels (or the amount of noise associated with restaurant).
For manufacturers, the Whisper Chip is simple to implement, sitting between the microphones and speech engine. It works with the leading operating systems, processors and speech recognition engines.
The Whisper Chip is an all-digital solution that runs at only 16MHz, consumes less than 12mW of power and replaces the CODEC no ADC or DAC is needed. It is also compact (4 x 4 mm) and accepts up to four (4) digital microphone inputs. The technology embedded in the Whisper chip is protected by more than 20 patents and patents pending.
Kopin Corporation is a developer of wearable computing technologies and solutions. Kopin's technology portfolio includes ultra-small displays, optics, speech enhancement technology, software, low-power ASICs, and ergonomically designed smart headset concept systems. Kopin's proprietary components and technology are protected by more than 300 global patents and patents pending, with more than 95% related to wearable technologies.
