1, OTP voice chip otp voice chip Sound quality is mainly related to the following factors otp voice chip : Sampling rate: The sampling rate is the number of audio signal samples otp voice chips obtained in one second. Higher sampling rates can capture more audio detail otp voice chip , provide higher sound quality. Resolution: Resolution refers to the number of digits that can be represented in each sample. Higher resolution can provide more accurate audio representation otp voice chip , thus improving sound quality.
2, NVC series octagonal voice chip is a new industrial OTP voice chip launched by Guangbaizhou Jiuxin Electronic Technology, which is suitable for factory mass production. It can be connected to external DAC circuit, with volume adjustment function, high sound quality, easy control, simple circuit, a variety of practical packaging forms and many other remarkable advantages, and can control multiple segments at willVoice trigger is the only voice chip on the market that supports 220 segments of sound with 8-pin chip.
3, audio quality: audio quality is an important factor affecting the anti-interference of OTP voice chip. For example, if the signal contains noise or noise, it will interfere with the chip's processing of the original signal. Software algorithm: The anti-interference of OTP voice chip is also related to the software algorithm used inside the chip. Usually, OTP voice chips contain some noise reduction algorithms to help improve the accuracy and anti-interference of speech recognition.
4, FLASH ROM and EEPROMCommonness is repeatable erasable, large storage space, can be freely changed control mode and voice content, can store a larger voice file. EEPROM is usually integrated in the chip, this type of voice chip is more expensive, such as ISD1700, ISD2500 and so on.
5, flexibility: OTP voice chip usually can only play the pre-recorded sound sample, so its sound content is fixed, the user can not change. In contrast, the TTS voice chip has more flexibility and can synthesize different speech in real time based on different text input by the user.
6,Music chips are commonly used in music players, audio equipment, car audio systems, etc. It can support a variety of audio formats, with sound adjustment, volume control and other functions. To sum up, OTP voice chip and music chip are different in function and use. The OTP voice chip focuses on storing and playing back pre-recorded voice messages, while the music chip focuses on playing back music files and providing audio decoding and amplification capabilities.
FlexibilityOTP voice chips usually only play pre-recorded sound samples, so its sound content is fixed and cannot be changed by the user. In contrast, the TTS voice chip has more flexibility and can synthesize different speech in real time based on different text input by the user.
Voice IC and voice chip are the same meaning, but the name is different. OTP is a kind of voice chip. The voice chip of OTP uses one-time programmable (OTP) memory as the storage medium of voice information. Once data is stored in OTP memory, it cannot be modified or updated; Have noCan be modified.
OTP voice chip refers to a one-time programming voice chip, which stores pre-programmed audio information, once programmed, the 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.
Analog Output otp Voice chip : Voice chip converts digital signal to analog electrical output. This output mode is suitable for applications that need to be connected to analog audio input devices otp voice chips , such as speakers, headphones, power amplifiers, etc. Digital Output: The voice chip outputs data in digital form, usually using standard digital interfaces (such as I2S, PCM, etc.).
Voice coreThe level triggering mode of chip is a common triggering mode, which triggers the work of voice chip by detecting the level change of input pin. Specifically, the level trigger mode usually includes the following: Rising edge trigger: When the level of the input pin changes from low (0V) to high (usually Vcc supply voltage), the voice chip is triggered to start.
According to the output mode of the voice chip is divided into two categories, one is the PWM output mode, the other is the DAC output mode, the PWM output volume is not continuous and adjustable, can not be connected to the ordinary power amplifier, most of the voice chips on the market are PWM outputOut of the way. The other is the DAC amplified by the internal EQ, the voice chip sound is continuously adjustable, can be adjusted by digital control, and can be connected to an external power amplifier.
Programmable one-time burning (OTP) voice chip; (2) The speech length can be selected 40 seconds, 80 seconds (6KHz sampling rate); (3) PWM audio output mode; (4) No additional shock resistance is required to provide a maximum number of 32 voice segments; (5) With key control mode, number pulse control mode; (6) Support to play voice files with different sampling rates; (7) Wide operating voltage: 8V ~5V.
Precise controlrong> is a semiconductor production process otp voice chip , on a small monocrystalline silicon chip to produce a number of transistors, resistors, capacitors and other components, and in accordance with the multi-layer wiring or tunnel wiring method to combine the components into a complete electronic circuit. ic chip purchase recommended widely praised Yunhan core City otp voice chip !

Voice chip refers to the IC that can store and control the playback of voice, also known as sound chip, audio ic. According to the output mode of the voice chip can be divided into two categories, one is PWM output mode, the other is DAC output mode. PWM output volume is not continuous adjustable, can not be connected to ordinary power amplifier, most of the voice chips on the market are PWM output mode. Generally used in smart home and security fields such as smart doorbell, alarm and other products.
IC refers to an integrated circuit, and a chip refers to a device based on integrated circuit technology. The full write of IC is integratedcircuit. Computers used to be assembled with thousands of tubes and transistors, if so manyAs long as one of the solder joints in the device is broken, the whole machine will not work.
Voice chip and microcontroller are two different chips, but they have a close relationship. This paper will deeply discuss the relationship between voice chip and single chip microcomputer to help readers better understand the characteristics and applications of these two chips. Voice chip: The realization of digital magic A voice chip is a chip with a special function that converts our voices into numbers and is stored in a small IC. Through clever circuitry, these numbers are restored to a beautiful sound.
recorded. The language chip,As the name suggests, it is an IC that can store and control the playback of speech. It means that the voice signal is converted into a number by sampling, stored in the ROM of the IC, and then the number in the ROM is restored to the voice signal through the circuit. From the point of view of use, the main way to use the voice chip is to record it first, and then use it after the recording is completed.
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.
