LD3320 ASR Non-specific speech recognition module with a microphone with the source crystal

1. On-board LD3320 speaker independent speech recognition (SI-ASR:Speaker-Independent Automatic Speech Recognition) speech recognition / technology voice chip.

2. Through the rapid and stable optimization algorithm, complete independent speech recognition, users do not need prior training and recording, also does not need any machine in the PC software..

3. Does not require any external auxiliary Flash chip, RAM chip and AD chip, can complete the function of speech recognition, and really provides a single chip solution for speech recognition...

4. Main control MCU on chip operation through reading and writing the chip internal registers finish.Through setting up and read the memory can easily complete set of speech recognition list, start the speech recognition, recognition result is obtained, playing the function of MP3.

5.The chip has prepared A 16-bit A/D converter, 16 bits D/A converter and amplifier circuit. A microphone,stereo headset and speaker can be conveniently and chip pin connection. Stereo headphone jack to 20 mw output power, and the output of the speaker interface power is 550 mw, can produce a loud and clear voice.

6. Support parallel interface and serial interface SPI two connection methods, serial method can simplify the connection with other modules.

7. Support for MP3 function, without periphery auxiliary components, main control MCU MP3 data in turn into LD332X chip internal can output sound from the chip D/A PIN.

8. The PCB board size: 43.5 (mm) x28.8 (mm).
