1, speech recognition accuracy: the speech recognition accuracy of different chips may be different Voice playback chip , it is necessary to choose the appropriate accuracy level according to the specific application needs. Processing speed and efficiency: The processing speed and efficiency of the voice recognition chip directly affect the response time and performance of the system Voice playback chip , which needs to be based on the actual application scenarioChoose the right processing power.
2, speech recognition chip compared with the traditional voice chip voice playback chip , the biggest feature of the speech recognition chip is to be able to voice recognition, it can make the machine understand the human voice, and can perform various actions according to the command, such as blinking eyes, moving the mouth (smart doll). In addition, the speech recognition chip also has the function of high-quality and high compression rate recording and playback, which can realize man-machine dialogue.
3, the main features of the voice chip are low power consumption, strong anti-interference ability, fewer peripheral devices, simple control, languageThe voice is stored for a long time (some voice chips can save the content for 100 years), the voice is not lost when the power is off, and some chips can also repeatedly erase the voice content. Such as car reversing radar, bus stopping device, bank queue machine, voice toys, anti-theft system and other equipment are equipped with voice chips.
Flexibility: OTP voice chips usually only play pre-recorded sound samples, so its sound content is fixed and the user cannot change it. Compare withThe TTS voice chip has more flexibility and can synthesize different speech in real time according to different text input by the user.
This is embedded in the music chip, music chip is a relatively simple voice circuit, it through the internal oscillation circuit, and then connected to a small amount of discrete components, can produce a variety of music signals, music chip is an important branch of the voice integrated circuit, Widely used in music electronic greeting cards, electronic toys, music candles, electronic clocks, electronic doorbells, household appliances and other occasions.
OTP speech chip refers to a one-time programming speech chip, which stores thePre-programmed audio information, once programmed, this data cannot be changed. The main application scenarios are as follows: Audio prompt: The OTP voice chip can be used to provide voice reminder functions, such as alarm clocks and timers. Message broadcasting: The OTP voice chip can be used to broadcast messages, warnings or emergency notifications.
The chip you're talking about is called a music film (also called a voice chip). It has solidified good music (sound) data, of course, it can also be a human voice, such as the bus station announcer, which stores more music, such as the doorbell, the music box is used above this thing. Generally inVoice chip Application range '>WT5001 Voice chip Application Range
1, WT5001-48L is a TQFP48 package chip designed for voice applications, it offers a variety of module package options, including DIP16 and DIP28. The chip has 8KB of OTP storage, an 8-BIT CISC architecture, built-in DAC and MP3/WAV decoders, can drive 16 ohm headphones, and has an excellent SNR of 93dB.
2, WT5001-48L is a specially designed for high sound quality requirementsOTP voice chip, using 8-BIT CISC architecture, support MP3 decoding, but also compatible with WAV format. The chip is equipped with a wealth of peripheral interfaces, including a DMA support SPI interface, can drive 16 ohms headset, built-in real-time clock and perpetual calendar functions, to provide users with accurate time management. It also has standard RS232 serial port control for easy remote operation.
3, WT5001 module is simpler to use than WT588D, does not need tools and PC software, through the U disk, TF card to download multiple MP3 files to FLASH, and then through the MCU serial command to call any segment of voice. Supports thousands of voice calls and internal playback.
1, WTV series voice chip, SYN6288 voice synthesis chip, etc. The WTV series voice chip is produced by Waytronic (Waytronic) voice player chip , with different voice player chip models and features, these chipsIt can be controlled by keys or serial ports, and supports recording and playing multiple voices with different storage capacities and playback duration.
2, Qiying Telen voice player chip : The technology pioneer in the field of domestic voice chip founded in 2015, Qiying Telen is the pioneer of domestic voice chip research and development, and the release of its CI1006 marks the birth of the first offline voice recognition chip in China. Their product line is rich, from CI1002 to CI2312, and the choice of numerous chip models provides users with flexibility.
3,Hello, if there is no special requirement for the sound quality of the voice played, the general voice chip can be used, and the voice duration can be increased with external SPIFlash.
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.
1, use WT588D voice chip. WT588D is a commonly used voice player chip voice player chip , which can be used with 51 single chip microcomputer to achieve voice broadcast 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.
2, you can use the voice recognition chip LD3320, circuit diagram you just under the voice playback coreThe pdf of the piece can know the voice playback chip , and there are typical applications in pdf. But I recommend you not to use this chip, it should be more expensive about 100 yuan. I recommend you to use the Sun 61 microcontroller, with its own voice recognition module, designed for speech. And the official provides many functions, you can call directly, do not need to write their own programs to control the intermediate processing of sound.
3, WTV series voice chip is produced by Waytronic company, with different models and functions, whichSome chips can be controlled by key or serial port, support recording and playback of multiple voice, with different storage capacity and playback duration.
Main features ISD1810 is a new product in the ISD series of voice recording and playback chips. It adopts analog direct storage technology, so it has high fidelity and good sound quality. Can be repeated 10,000 times; Information can be stored for 100 years; ISD1810 uses a single power supply 3V power supply, its record and release gap circuit can automatically enter the power saving state, and maintain powerThe flow is only 0.5μA.
Electrical characteristics Operating voltage: 4V-5V, the maximum can not exceed 6V, static current: 0.5-1 μA, working current: 20mA, the user can use the oscillation resistance from the sampling frequency of the chip, so as to determine the chip recording and playback time. 3 Independent key working mode The ISD1760's independent key working mode recording and playback circuit is very simple and powerful.
