Speech (Voice) Recording & Playback Unit - Industrial Class
Description:
Package of 28 pin (by pitch 2.54mm) module adopts WT588D-U voice chip as control core, which can be replaced memory for gaining different lengths of storage time. When the peripheral is connected to power, the speaker and the control terminals will work. With the built-in DSP processor and embedded human voice processing technology, it provides not only excellent sound quality, but also flexible control modes, supporting MCU and key controls. Being integrated with computer software, it can be operated to add, delete and replace voice content freely.
Features:
* Package of 28 pin module, which can be replaced memory for gaining different lengths of storage time;
* Support SPI-Flash by the capacity up to 32M;
* WT588D-U voice used as a control core chip;
* Embedded human voice processor makes it sound very natural;
* Good audio quality output for 13Bit/DA converter and 12Bit/PWM processing of audio;
* Support loading 6K ~ 22KHz audio sampling rate;
* PWM output can directly promote 0.5W/8 Ω speakers and plenty of current;
* Support DAC / PWM output;
* Support loading WAV audio format;
* Support key control mode, one-wire serial control mode, three-wire serial control mode;
* A variety of I/O trigger ways can be set in button control mode;
* The way of BUSY signal output can be set in a random manner;
* Loading no more than 500 segments voice for editing;
* Address bit is controlled by 220 segments voice, but just a single address bit can load up to 128;
* Once voice player enters the sleep mode it will stop immediately;
* A lot of operations can be finished in software, such as setting up control mode, inserting voice, composing voice, and etc.;
* Free to insert mute, mute time range 10ms ~ 25min;
* Support online USB download / offline USB download. What’s more, it also can download data to SPI-Flash even if WT588D-U are working;
