What is the process of developing voice chip products?

Firstly, you can select the appropriate chip or module through the relevant instructions in the document. Actual testing of voice effects and product features. If your product requires mass production, you can directly purchase the chips or modules provided by our company in bulk. Based on the hardware design information in the platform design data, you can design your own circuit board, debug it, and then conduct product performance testing, reliability testing, and production testing according to the testing methods provided in the documentation center to meet the requirements of the entire machine for mass production.

How to improve speech recognition performance?

There are many factors that affect the effectiveness of speech recognition, such as the performance of the speech chip itself, the selection of keywords, and the structural design of the product (such as the installation position of the microphone and speaker). We recommend that you directly use Weichuang Zhiyin’s voice chip products and voice AI platform for development. Our company has accumulated a lot of technology and products, and the standard solution recognition rate can reach 97%. You can also directly ask our technical assistance to optimize and further improve the voice recognition effect.

What are the advantages of offline voice solutions compared to pure online?

The offline voice solution uses professional offline voice chips to process voice at the terminal without connecting to the network, which can maximize the protection of user voice privacy. It can also be used after network disconnection, saving network costs and bandwidth. The offline voice solution has good real-time performance and can respond within 1 second. There is no delay problem caused by network congestion or poor signal in the cloud solution, making it very suitable for use in functional control products such as small and medium-sized appliances, automobiles, lighting, and other fields.

Can voice content be modified directly through MCU control?

Waytronic’s WTK6900FC chip supports serial port updates for voice entries and replies.
