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.
ic andThe difference between chips is mainly: chip is a general term for semiconductor component products; IC is an integrated circuit, which uses a semiconductor production process to make many transistors and resistors, capacitors and other components on a small monocrystalline silicon sheet, and combines the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring.
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 tens of thousands of tubes and transistors, if so many devices, as long asIf one of the solder joints breaks, the whole machine will not work.
Voice chip and single chip microcomputer is the perfect combination of digital magic and microcomputer. Voice chip is a kind of hardware device that can store and play voice information, which usually contains digital signal processor (DSP) and memory, which can convert voice signal into digital signal for storage and playback.
Voice chip is a kind ofA chip with a special function that converts our voices into numbers and stores them in tiny ics. Through clever circuitry, these numbers are restored to a beautiful sound. With the advent of the voice chip, digital magic became a reality.
Parallel control mode 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, and before and after operation. There is also a voice microcontroller.
Hello is OK. The parallel control form voice chip provides the key interface, and can use the I/O port of the single chip computer to control the voiceCompared with the voice chip, the biggest feature of the voice recognition chip is that it can recognize speech, which can make the machine understand the human voice, and can perform various actions according to the command, such as blinking eyes and moving the mouth (smart doll).
2, speech recognition accuracy: the speech recognition accuracy of different chips may be different, and the appropriate accuracy level needs to be selected 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, and it is necessary to choose the appropriate processing capability according to the actual application scenario.
3, the main feature of the voice chip is power consumptionLow, strong anti-interference ability, few peripheral devices, simple control, long voice storage time (some voice chips can save the content for 100 years), no loss of voice after power failure, some chips can also repeatedly erase and write voice content.
4, the voice chip refers to the IC that can store and control the playback of voice, also known as the 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.
5, Scheme 1: MCU 74HC573 latch chip clock chip voice broadcast chip; Option two: MCU 74HC573 latch chip crystal oscillator voice broadcast chip; The scheme we will introduce below only needs MCU WT588F02KD-24SS chip second hop chip to achieve the functional requirements required by the above scheme design.
6, recommended NV080C, it has no minimum amount of restrictions, stable performance, high sound quality, cheap price. Suitable for application in the range of small household appliances.
RootAccording to the voice chip output mode can be divided into two categories, one is PWM output mode, one 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.
The audio signal is directly output from the PWM pin of the chip without the power amplifier, and the audio signal without the power amplifier can not be played directly by the speaker, so the chip with the DAC output mode can only be played by the external power amplifier, and cannot be directly pushed by the speaker.
Speech chip Speech chip definition: the speech signal is converted into a number by sampling, stored in the ROM of the IC, and then through the circuit to restore the numbers in the ROM into a speech signal.
Common DAC input can be binary code, pendulum width modulation (PWM) and other forms, the output can be voltage type, currentType and other forms. DAC is widely used in electronic equipment, such as audio equipment, communication systems, instruments and so on.
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.
OTP Voice Chip (One Time Programmable Voice Chip) : An OTP voice chip is a chip used to store and play back pre-recorded voice information. It usually has a small audio processor built in that can store and play back single or multiple speech clips.
Speech chip Speech chip definition: the speech signal is converted into a number by sampling, stored in the ROM of the IC, and then through the circuit to restore the numbers in the ROM into a speech signal.
This article will delve into the relationship between voice chip and microcontroller to help readersBetter understand the features 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.
The most common words are used to regulate the playing and receiving of sound. For example, your own mp4, here the most important is the audio decoding chip and video decoding chip and memory chip if you want to put the first call memory chip data through the audio decoding chip processing to put out.
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; Has unmodifiable properties.
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 categoriesOne is PWM output mode, the other is DAC output mode.
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. The playback function of the ordinary voice chip is essentially a DAC process, while the ADC process data is completed by the computer, including the sampling, compression, EQ and other processing of the speech signal.
