Universality principle: The selected voice chip should be widely used and verified, and have been studied by a large number of experiments. 2) The principle of high cost performance: In the case of similar functions, performance and utilization, try to choose inexpensive voice chips to reduce costs.
YQ5969 is recommended, the module series can support 1-8 mics, the voice coreThe chip can provide different solutions of single-core - 4-core 32bitARM core according to the specific needs of customers, which 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%.
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 requirements. 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.
YQ5969 is recommendedThe voice recognition remote control can support 1-8 mics, and can also support local and cloud recognition of different needs. The local recognition rate within 5 meters is more than 93%, and the cloud recognition rate is 97%.
Recommended NV080C, it has no minimum limit, stable performance, high sound quality, cheap price. Suitable for application in the range of small household appliances.
Non-specific person speech recognition chip, MCU can pass the Chinese pinyin string identification words to LD3320 by reading and writing registers, start speech recognition work. This individual thinks best. And then there are the original chip manufacturers like Sunline, Sunline,There are also many secondary development companies like Chengxin Sheng Silicon Jet! Not bad, too.
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.
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 speechThe signal.
In the current era of advanced science and technology, integrated circuit is an indispensable component to promote the development of science and technology. The voice chip, as the name suggests, is an IC that can store and control the playback of speech.
Zhiduo Bear is jointly built by the three places on both sides of the Taiwan Strait, which perfectly integrates the early education and entertainment functions of early education machines, intelligent toys, teddy bears and children's speakers, and materializes the abstract early education theory and professional measures into an early education intelligent toy.
That is to say, the voice chip is a chip with a specific function, and the single chip microcomputer is like a computer, on the basis of it, you can realizeElectricity, to achieve the smart home scene construction. In addition, voice recognition technology can also be used in voice search, telephone customer service and other fields.
3, smart home control: through voice commands to control the home lights, appliances, curtains and other equipment, improve the convenience and intelligence of the home. Voice Assistant: such as Siri, Google Assistant, etc., they can understand and execute the user's voice commands, information query, schedule management, set reminders, etc.
4, the AI chip can help the speech recognition system to better recognize the speech signal and convert itConvert to text or practice. Smart homes have become an indispensable part of people's lives, and the application of AI chips also makes smart homes more intelligent.
