WT588D is a voice chip with a microcontroller core, so it can be named WT588D series voice microcontroller. WT588D series speech microcontroller is an edit-able speech chip which is developed by Guangzhou Vichuang Electronics Co., Ltd. and Taiwan Huabang. It integrates single chip and speech circuit.
WT588D Voice chip WT588d voice chip is an early voice chip that can be attached to FLASH, WT588D voiceThe quality is better, the control is flexible, and the function of MIDI chord can be played is increased, and the performance is better.
WT588D is a voice chip that is packaged in DIP1SSOP20 and LQFP32 forms.
Using the WT588D voice chip. WT588D is a commonly used voice chip, which can be used with 51 single chip microcomputer to realize voice broadcasting function. In the design of bus station announcement system, WT588D can be used as recording module, which is controlled by 51 MCU to play different voice files.
I think WT588D shouldBetter, first of all, the function is much stronger, a lot of control methods, and also with a single chip computer.
OTP voice chip has a variety of options: WTV040, WTV080, WTV0 WTB031 (Iron General anti-theft device is widely used), WTH040 (a large number of blood pressure monitors in use), WTH080. There are voice microcontroller: WT588D (the United States high-end rice cooker, high-end washing machine in a large number of use, treadmill in use), WT681 are a good choice.
If the address is triggered first or the wt588d voice chip other command wt588d voice chip , wait 90ms before sending the volume adjustment command. The loop play command needs to wait for 30mswt588d voice chip , and before the voice playback ends. The WTV chip will restore the voice to the maximum wt588d voice chip after each sleep, so the volume command needs to be re-sent every time it plays.
The first kind, called OTP, is the kind of SOP8 package voice chip, built-in several commonly used voice, after the factory on the fixed phone die wt588d voice chip , can not be modified the second kind, called flash voice chip, usually a master chip attached to aspiflash, the master chip is unchanged, and flash can be repeatedly burned, but the voice often only supports wav, so the sound quality will be very poor compression.
WTV series and WT588D voice chips, are Guangzhou Vitron Electronics, research and development and production of voice chips, strong industrial, not easy to be disturbed, sound quality is also very good.
1, WT588D is a voice chip with a single chip microcomputer core, so it can be crownNamed WT588D series voice microcontroller. WT588D series speech microcontroller is an edit-able speech chip which is developed by Guangzhou Vichuang Electronics Co., Ltd. and Taiwan Huabang. It integrates single chip and speech circuit.
2, WT588D is a voice chip, chip package DIP1SSOP20 and LQFP32 form.
3, WT588D voice chip WT588d voice chip is an early voice chip that can be attached to FLASH, WT588D sound quality is better, flexible control characteristics, but also increase the playback MIDIChord function, better performance.
4, use WT588D voice chip. WT588D is a commonly used voice chip, which can be used with 51 single chip microcomputer to realize voice broadcasting function. In the design of bus station announcement system, WT588D can be used as recording module, which is controlled by 51 MCU to play different voice files.
5, WT588D this voice chip does not need to write, it provides a variety of interfaces can be controlled through the single chip microcomputer to play, voice content and interface mode is downloaded and set by the upper computer software. The WT588D has an S insideThe capacity of PI-FLASH and SPI-FLASH determines the length of the file that can be played.
1, AT89C51 chip. According to 51 SCM voice broadcast version information display: 51 SCM voice broadcast design is composed of AT89C51 for the main control chip LCD12864 LCD display clock voice alarm module infrared remote control.
2, use WT588D voice chip. WT588D is a commonly usedThe voice chip can be used with 51 single chip microcomputer to realize the voice broadcasting function. In the design of bus station announcement system, WT588D can be used as recording module, which is controlled by 51 MCU to play different voice files.
3, the question is not clear. There are many voice chip models, most of which can handle multiple voice messages, so in principle they can be controlled by 51. Because the voice chip is actually a voice memory chip, each information segment must have an address code, if you want to play which voice, use 51 to call this address, you can achieve voice playback.
4What do you want, voice recognition? This has a special chip, of course, to cooperate with the single chip microcomputer, there is also a direct module with the single chip microcomputer. For example, LD3320. The operation is very simple, the need to identify a number of phrases or statements pinyin into the chip, and then start the recognition, find the relevant register, know whether the recognition is successful, the success of the identification can be returned to its successful comparison with the serial number, and then the single chip machine performs the corresponding functions, such as voice broadcast, or turn on and turn off the light.
5, non-specific person speech recognition can look at NRK10 this offline voice chip. NRK10 voice recognition chip for GuangzhouA high-performance, low-cost offline speech recognition chip independently developed by Nine core Electronics, with speech recognition and broadcast functions, which requires external SPI-Flash to store terms or voice broadcast content. It has the advantages of high recognition rate, industrial grade performance, simple to use, easy to update terms and so on.
6, in fact, you can use the PC to broadcast these information, write a software is OK, with a piece of chip connected to the computer serial port to engage in a dual-machine communication. In fact, this will also have problems, the computer can not work for a long time, so you need to use a stronger film to do, PIC or AVR choose a film to do
