The chip integrates speech recognition processor and some external circuits, including AD, DA converter, microphone interface, voice output interface and so on. This chip does not need any auxiliary chips such as FLASH, RAM, etc. it can be directly integrated into the existing products to realize the voice recognition / voice control / human-computer dialogue function. The key words list can be edited dynamically. The chip is used in induction cooker, microwave oven, smart home appliance operation, navigator, MP3, MP4, vending machine, public lighting system, health system and smart home voice control.\n\nLibDriver LD3320 is a full-featured driver of LD3320 launched by LibDriver.It provides voice recognition, MP3 playback and other functions. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example asr](#example-asr)\n    - [example mp3](#example-mp3)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver LD3320 source files.\n\n/interface includes LibDriver LD3320 SPI platform independent template.\n\n/test includes LibDriver LD3320 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver LD3320 sample code.\n\n/doc includes LibDriver LD3320 offline document.\n\n/datasheet includes LD3320 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
