The new software technology combines several company-proprietary algorithmic techniques and is available on all products across the company's integrated circuit platforms. While all applications for speech recognition and speaker verification can benefit from Sensory Speech 2.0, the software was designed for the consumer telephony market where products are used primarily in home and automobile environments. Applications such as voice dialing for telephones and voice commands for answering machines will especially benefit from the technology advances. Noise in the Real World A critical success factor in utilizing voice-controlled products is the ability of the speech chip to distinguish background noise from the speaker's voice. In order to filter out noise, the chip must distinguish between speech and two types of background noise.
Stationary noise is continuous, such as a fan or traffic noise.
Non-stationary noise is intermittent, such as a door slamming or people talking. Both types of noise can degrade speech recognition accuracy. Sensory Speech 2.0 addresses these noise factors and improves the amplitude control and definition of detected sounds. Now our accuracy is superior to the traditional DSP-based approaches even in noisy environments. This will allow Sensory to offer superior solutions to our primary market segment, the consumer telephony equipment manufacturers.
