Why is the voice recognition chip the core of the ambient light voice controller?

As an important element and design for lighting up car interiors, interior lighting has attracted more and more attention from OEMs and consumers in recent years. For OEMs, interior ambient lighting is not only a decoration that creates the interior atmosphere and reflects personality, but is also a major reflection of brand recognition.

For consumers, they want comfort, technology and a diverse space experience in the car, and ambient lighting can just meet the various sensory needs of different environments.

The ambient light voice controller can conduct human-machine dialogue, and the ambient light controller drives specific parts to flash corresponding voices. The ambient light can be controlled by voice to set the color operation effect from the front of the vehicle to the back.

Ordinary ambient light controllers mainly control the ambient light switch through a remote control, and there is no way to achieve voice control. With the intelligent voice ambient light controller, you only need to shout to control the car ambient light switch, without using a remote control. Ambient light controller manufacturers choose Geyuan Electronics’ low-cost GYK3301 offline voice chip to realize voice control of ambient lights.

GYK3301 speech recognition chip is an offline speech recognition chip. It adopts the latest neural network (TDNN) algorithm. It has the advantages of accurate recognition and low misjudgment rate. It has reliable recognition in the 5-meter far field. It has built-in 1MBSPIFLASH and can support no more than 100 offline instructions. ; VBAT is 2.2V to 5.5V; VDDIO is 2.2V to 3.6V.

It also adopts a speech noise reduction algorithm: it filters out steady-state noise and has a good suppression effect on dynamic noise. It can also be accurately recognized under noise, with a recognition rate as high as 95%;

Supports MP3, WAV, WMA, APE, FLAC, AAC, MP4, M4A, AIF, AIFC audio decoding, which has great advantages in audio compression and is very convenient.

It can support up to 100 offline instructions and is now widely used in smart home appliances, smart bathrooms, smart lighting, smart electromechanical, smart homes, smart toys and other fields.
