Speech recognition chip It is also called voice recognition control IC. Compared with the traditional voice playing chip, its feature is that it can recognize voice content and execute actions according to instructions, just like a machine can understand human language and make corresponding feedback to realize human-computer dialogue. Customers can choose voice recognition IC or voice recognition module to apply to products according to their own needs.

The latest generation of recognition algorithms and advanced acoustic model and language model training methods are adopted for the voice recognition technology of Weichuang Zhiyin, and the recognition rate is at the leading level in the industry. Support far-field speech recognition, up to 10 meters in a quiet environment; Support autonomous learning of voice model. In offline state, users can customize wake-up words and command words by entering voice; Integrated infrared code library, supporting infrared code learning function. The voice recognition technology of Weichuang Zhiyin is highly practical in various fields and application scenarios. With its profound technical precipitation, it has a considerable number of successful cases in many fields, and has a high degree of maturity.

Our speech recognition scheme is speaker independent speech recognition technology. At present, we have WTK6900F-B03, WTK6900G-B01, and WTK6900H-M01 speech recognition modules. The products can be widely used in kitchen appliances, lamps, personal care appliances, bathroom, elevators, voice toys, etc;

Recognition function: it can recognize the preset voice entries, and output the recognition results through serial port, IO;

Play function: play the specified voice through the MCU command, and check whether the voice is playing through the BUSY pin mark;
