LD3320 ASR non specific speech recognition module with IMI headband active crystal oscillator

Description: 1. onboard LD3320 non-specific speech recognition (SI-ASR: Speaker-Independent Automatic Speech Recognition). Speech recognition technology / voice . 2. through rapid and stable optimization algorithm, to complete the non- specific speech recognition , users do not need prior training and recording , do not need any software on the PC . 3. does not require any external auxiliary Flash , RAM chips and AD , you can complete a voice recognition function , really provide a single- speech recognition solutions. 4. The operation that the master MCU to is completed by the reader in the internal registers. Can be easily accomplished setting of the list of voice recognition by register settings set , voice recognition start , get the recognition result , MP3 player and functions. 5 has prepared a 16-bit A/D converter, 16-bit D/A converter and amplifier circuits. Microphone, stereo headphones and mono speaker can be easily connect to pin . Stereo headphone jack output is 20mW, and the output of the speaker interface is 550mW, can produce a loud and clear voice. 6. Supports parallel and serial interface two kinds of connections , serial connection can simplify connections with modules. 7. Supports MP3 playback, without external auxiliary devices, the master MCU will turn into LD332X MP3 data can sound from the D/A PIN output. 8. board Dimensions : 43.5 (mm) x28.8 (mm)
