LD3320 ASR the Specific Speech Recognition Module with Microphones with the Source Crystals

Item specifics:
- Model Number: LD3320 ASR

Product Description:
- Onboard LD3320 -independent speech recognition (SI-ASR: Speaker-Independent Automatic Speech Recognition) technology, voice recognition / voice chip.
- Through rapid and stable optimization algorithm , the completion of non- specific voice recognition , without your prior training and recording , do not need any software on the PC .
- Does not require any external auxiliary Flash chip , RAM chips and AD chip , you can complete voice recognition capabilities , really provide a single-chip speech recognition solutions.
- Master MCU operation of the chip reader chip internal registers through completion . By setting and read registers can easily complete list of voice recognition settings , start voice recognition, recognition results obtained , MP3 player and other functions.
- Chip has prepared a 16-bit A / D converter , 16- bit D / A converter and amplifier circuit . Microphone , stereo headphone and mono speaker can be easily and chip pin connections. Stereo headphone jack output power of 20mW, and the speaker port output power 550mW, can produce a loud and clear voice.
- Support parallel interface and serial interface SPI two connections , serial mode can simplify the connection with other modules .
- Supports MP3 playback function , no need of peripheral auxiliary devices, the master control the MCU will MP3 data is sequentially fed into the LD332X the chip internal you can from the chip 's D / A PIN output the sound.
- PCB board Dimensions : 43.5 (mm) x28.8 (mm)
