WTK6900FC-M01 is the recognition module of the local voice trigger engine. Based on the most advanced deep neural network (DNN-HMM) voice recognition technology, the module realizes high recognition rate, high real-time performance, local and cloud combination, and highly integrated voice recognition and processing functions; it can realize specific intelligent voice interaction effects such as semantic recognition. At the same time, the module has the control and computing processing capabilities of a conventional MCU, and can realize various applications that require communication and control. In terms of application, the module can support local voice detection and wake-up, offline 5-8 meter far-field recognition, and three hundred offline command entries. The module can push commands to the original host computer of the device through UART to realize a simple voice interaction interface. The module solution also supports multiple global languages such as Chinese, English, and Japanese, and can be widely used in home appliances, lighting, toys, wearable devices, industry, automobiles and other product fields to realize voice interaction and control and various intelligent voice solution applications.

The hardware connection method of the chip UART interface is shown in the following figure:

Chip electrical characteristics

NOTE1: 5V is the typical input voltage of the module. Input voltage exceeding 5.5V will damage the module (including ripple).NOTE2: A set of power input with a driving capacity of 460mA needs to be reserved for the module. The maximum current of thespeaker when broadcasting may reach 460mA NOTE3: The typical value is measured in the silent state. The maximum value is forrecognition and broadcasting. Depending on the speaker model, a maximum current input of 460 mA may be required. NOTE4: The moduleneeds to be stored in a vacuum. After opening, it needs to be placed in a 5%RH drying cabinet and soldered within 48 hours. NOTE5:The 5V power supply must ensure a rated power supply capacity of 460mA. The power supply must be clean and the ripple must bearound 50mV; NOTE6: The serial port level of this module board is a 3.3V system. If you need to connect a 5V logic level, pleasecontact the supplier

Delivery terms of EXW, FCA, FOB, DDU etc. are all available based on each quote. Q9. Shipping cost? The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.Q10.What is a bin file?The bin file (binary file) is a computer file format in which the data contained is represented in binary form. This file format is commonly used to store program code or other data, such as images, audio, video, etc.Unlike text files, bin files do not save data in a readable text format. Instead, it stores data in binary format, which means that data is represented in a bit pattern of 0s and 1s. This makes bin files usually more compact and faster to read and process than text files. WT588F02B-8S cannot directly read WAV, MP3, and other voice files but needs to be converted into bin files by upper computer software before being read.
