What are the low-cost offline speech recognition chips that are currently used more?

Compared with the traditional 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).

Recommend the use of YQ5969, this voice recognition remote control can support 1-8 head, can also support local and cloud recognition of different needs. The local recognition rate within 5 meters is more than 93%The cloud recognition rate is 97%.

NRK10 speech recognition chip is a high-performance, low-cost offline speech recognition chip independently developed by Guangzhou Jiuxin Electronics, with speech recognition and broadcast functions, non-specific voice print, need to external SPI-Flash, store terms or voice broadcast content.

Supports voice control. According to the letter of asr-pro chip usage instructions, the role of asr-pro is to support voice control, wake up the small black box through the wake word, and realize the corresponding function after saying the command.

NVB series voice chip3 Chip N9200, N920N9100, N9102 can be external FLASH, through USB connection computer update audio source, audio source can also be erased; If you want to built-in FLASH voice chip you can look at the NVF chip. These FLASH capacity sizes can be selected according to user needs.

NRK2202 can make the air conditioner, fan, lighting and other equipment in the user's home become intelligent offline voice recognition interactive infrared solution. This offline voice recognition solution can control home appliances by voice without networking or downloading an APP.

OTP voice chip refers to a one-time programmable voice chip, the voice can only be written once, suitable for application in the occasion that does not need to modify the voice. OTP voice chip is characterized by low cost, convenient control, simple circuit, suitable for factory mass productionClass of industry. Voice function chips with OTP include NVB, NVC and NVD.

CI1102 or CI1103, our single mai local speech recognition compatible module uses the CI110 is the use of neural network processor (BNPU), support speech detection, speech recognition, voice print recognition, dual Mai speech processing. Operating frequency 160MHz, support single mai far field noise reduction.

OTP voice chip has a variety of options: WTV040, WTV080, WTV0 WTB031 (Iron General anti-theft device is widely used), WTH040 (lots of blood pressure monitors in use), WTH080.

How to select a voice chip

1, speech recognition chip compared with the traditional voice 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).

2, 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 expanded SPIFlash increases.

3, scheme 1: MCU 74HC573 latch chip clock chip voice broadcast chip; Scheme 2: 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.

What are the commonly used voice chips?

1, WTV series voice chip, SYN6288 speech synthesis chip, etc. The WTV series voice chips, manufactured by Waytronic, come in different models and features. These chips can be controlled by a key or serial port, supporting the recording and playback of multiple voices, with different storage capacities and playback duration.

2, a lot of, for example, the most commonly used voice chips on the market have NVB, NVC and other series of voice chips, these chips have low cost, stable performance, high sound quality, easy control, simple circuit and many other significant advantages.

3, this, you can look at KT404AOr KT403A chip solution, this is currently much better than the ordinary OTP voice chip, the sound quality is very good, voice download directly through the usb interface of the chip, without the need for upper computer software, support tf card or u disk and other external devices.

4, HCS12 series, PIC series, AVR series, etc. Voice mouse chips include but are not limited to HCS12 series, PIC series, AVR series, ARM series and Sun single-chip microcomputer series.

5, ICRoute company's LD3320, non-specific person's speech recognition chip, MCUBy reading and writing the register, the identification words of the Chinese pinyin string can be passed to the LD3320, and the speech recognition work can be started. This individual thinks best.

6, Hengxuan was founded in 2015, Hengxuan Technology headquarters is located in Shanghai Hengxuan Technology is mainly engaged in intelligent audio SoC chip research and development, design and sales, provide AIoT scene with voice interaction ability of edge intelligent master control platform chip, products are widely used in smart Bluetooth headset, Type-C headset, Smart speakers and other smart terminal products.

What China hasA smart voice chip?

Bluetooth headset chip ranking is Hengxuan, Ziguang Zhanrui, Loda, Realtek, Jeri.

Domestic do better: iFlytek, Baidu, Alibaba, cloud sound, Jiatong Huaseng, Sibit and so on.

Domestic chip leading representative Torch core technology is definitely an outstanding representative, more than 20 years of deep cultivation in the field of sound, the research of sound has an exclusive advantage, the launch of many intelligent voice platform has been adopted by many first-line brands at home and abroad, the market reputation is very good, high customer requirements of the actual combat is Torch core products over the years excellent foundation.

What type of voice chip does the near-current alarm use?

1, the exclusive use of separate high-sensitivity, high-strength anti-interference wireless digital receiver module, to solve the common intelligent alarm in the critical state of high false alarm, high false alarm technical problems.

2, Abstract: Systematically introduces the basic principle of intelligent wireless anti-theft system, the composition of the block diagram, describes the telephone network receiving method in detail; The circuits of pyroelectric infrared sensor and voice are discussed, and some basic circuits and software flow are given.

3, this should be a shock alarm, piezoelectric ceramic plate is an induction element, potentiometer for vibration sensitivity fine tuning, red wire connected to positive 12 volts, black ground (negative), blue line is the alarm output.

4, the use of audion to design a burglar alarm requires a special description of the device, the device model in the circuit, the function. And write out the status quo, application and development of photoelectric triode.

5, voice chip classification: the common chip classification on the market now: short-time chips have 10 seconds, 20 seconds, 40 seconds, 80 seconds, 170 seconds chip, for model: WTV series and ISD1700 series chips commonly used modules are: 6 minutes, 8 minutes, 16 minutes, 1 hour and so on.
