ISD1760 independent key mode recording and playback circuit is very simple and powerful. There are not only recording and playback functions, but also fast forward, erase, volume control, direct playback and reset functions. These functions can be accomplished with just the touch of a button.
Voice chip ISD is a chip with a power supply range between 4V and 5V and a sampling rate between 4K and 12K.
DSP chip advantages: low cost, low power consumption, high performance processing power. The DSP chip generally has some main characteristics as follows: (1) One multiplication and one addition can be completed in one instruction cycle. (2) The program and data space are separated, and instructions and data can be accessed simultaneously.
ISD1700 series Good, ISD1700 is developed on the basis of ISD400ISD2500, ISD1400, cheap and easy to control. ISD4004 and ISD2560 are the products that will be eliminated, so don't study them. ISD4004 has SPI interface, can be serial control; While ISWhat are the advantages of QSOP24 packaged voice chips?
1, voice chip support PWM (pulse width modulation) output has the following advantages: precise control output: PWM output can be precisely controlled by adjusting the width and period of the pulse output level. This makes it possible for voice chips to achieve high-precision voltage or current output for driving horns, speakers or other audio devices.
2, interactivity: the voice recognition chip can allow smart toys to have a more natural and direct interaction with children, so as to better enhance children's communication and social skills.Educational: Smart toys equipped with speech recognition chips can help children conduct independent learning and language training, thereby improving their language expression and understanding.
3, offline voice recognition chip usually has the following advantages: privacy protection: offline voice recognition chip processes voice data locally, there is no need to transmit audio to the cloud for processing, so it can effectively protect the privacy of users.
WTV series voice chip by WaytronicProduced by the company, with different models and functions, these chips can be controlled by key control or serial port, support recording and playback of multiple voice, with different storage capacity and playback duration.
Voice alarm system, should contain the following modules: alarm sensor detection module, control module, voice module, GPRS or GSM or DTMF module.
First, you need to determine what you want to broadcast and when. Include morning greetings, the day's schedule, and good night words at night. You need to set the time of broadcast, for example, at a specific time of day.
YQ5969 is recommended, the module series can support 1-8 MI head, the voice chip can provide different solutions of single-core - 4-core 32bit ARM core according to the specific needs of customers, can support local and cloud identification of different needs. The local recognition rate within 5 meters is more than 93%, and the cloud recognition rate is 97%.
1, OTP voice chip refers to a one-time programmable voice chip, voice can only burnWrite once, suitable for applications that do not need to modify the voice. OTP voice chip is characterized by low cost, convenient control, simple circuit, suitable for industrial grade factory mass production. Voice function chips with OTP include NVB, NVC and NVD.
2, the chip you are talking about is called music film (also called 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.
3, OTP (One Time Programable refers to a one-time programmable voice chip, the voice can only be written once, suitable for application in the case of no need to modify the voice, the length of the voice is short, from the length of playback can be divided into 10 seconds, 21 seconds, 42 seconds, 85 seconds, 170 seconds, 340 seconds.
4, OTP voice chip refers to a one-time programming voice chip, it stores has been pre-programmed audio information, once programmed, these data can not 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.
1, the voice chip is a chip with a special function, it can convert our voice into a number, and stored in a small IC. Through clever circuitry, these numbers are restored to a beautiful sound. With the advent of the voice chip, digital magic became a reality.
2, voice chip and microcontroller is the perfect combination of digital magic and microcomputer. The voice chip is a kind ofA hardware device capable of storing and playing voice information, which usually contains a digital signal processor (DSP) and memory, which can convert voice signals into digital signals for storage and playback.
3, parallel control form voice chip provides key interface, the input and output port of the single chip can control the key interface of the voice chip for recording, playing, deleting, before and after operation. There is also a voice microcontroller.
may be the Bluetooth speaker battery is low, or the phone is not properly connected to the Bluetooth speaker. You can try the following methods to reconnect. The phone is not connected to a Bluetooth headset. The solution is to re-pair. First, turn off the Bluetooth headset and then long press the Bluetooth headset multi-function button to activate the Bluetooth headset and the phone to re-pair.
should be the program is not adjusted well, have the opportunity to discuss it together; Other questions about the voice chip can also be learned together.
Confirm the music file formatAnd storage: Ensure that the format of the music file matches the supported format of the MCU voice module, and the storage medium (such as SD card or flash memory) reads normally, incompatible music file formats or read errors can lead to timeout exit.
wechat voice always interrupted may have a variety of reasons. Some of these reasons may be due to network instability, problems with the mobile phone system, wechat application failure or mobile phone hardware problems. Network instability is one of the common reasons for wechat voice interruption.
