How to select voice chip and how wide is the application range of voice chip

Time:2022-11-01 Views:1632
    Chip is a very important electronic device. It can be said that enterprises or countries with strong chip manufacturing capabilities occupy an important position. In order to enhance everyone‘s understanding of the chip, this article will introduce the application scope and selection of voice chip. If you are interested in voice chips, you might as well read on.


1、 Application scope of voice chip
    Voice chips can be seen everywhere in our lives. For example, when we open the birthday greeting cards we receive, we can hear a pleasant song. In fact, this is the voice chip at work. At present, this kind of chip that can make sound is also popular in all walks of life, and voice chip manufacturers have also received a steady stream of orders. So what is the application scope of this chip?


1.1. Security alarm
    The voice chip has a wide range of applications in security alarm, such as our common reversing radar, forklift alarm, home anti-theft, access control system, etc., all use the voice chip as the main equipment to send alarm, which can send out a warning sound at the same time of warning, draw the attention of people around and remind people to deal with the alarm as soon as possible;


1.2. Medical devices
    Nowadays, we can also see the voice chip in many medical devices, especially in the amblyopia therapeutic instrument, blood pressure meter, ozone therapeutic instrument, blood glucose meter and other instruments. The use rate of voice chip is very high. At present, many medical devices that are convenient for the elderly are equipped with this voice chip, which can inform the elderly friends of the measurement results by voice;


1.3. Advertising media
    In many shopping malls and stores, you can often hear the voice welcome words like Welcome to Guanlin, which is actually the effect of the use of voice chips. Common voice billboards, mirror advertising machines, greeters, advertising devices, etc. are all equipped with voice chips, which can enable dumb billboards to play fluent slogans. In particular, the appearance of greeters has become an effective way to replace welcome etiquette personnel;
    The voice chip with guaranteed quality is also used in children‘s toys, such as cars, dolls and other products, which can make toys emit happy songs and can also make toys become talking playmates. The voice chip is also used in transportation vehicles now. The common voice chips are voice electric cars, voice bus stations, etc., and the application scope of voice chips will be more extensive in the future.


2、 How to select voice chip
    Speech chip is to convert speech signal into digital through sampling, store it in ROM of IC, and then restore the digital in ROM to speech signal through circuit.
    The voice of the voice chip is mainly determined by the sound when the chip is burning. First, the voice chip is applied to the circuit board, and then the program writes some keys or levels and other playing modes to trigger the voice broadcast. A small amount of storage space is built in the voice chip, with a capacity of about 1Mbit~4Mbit, which can store voice capacity of about 40-160 seconds. The chip can also be controlled by keys or MCU. It is an integrated circuit chip that can directly emit sound.
    Generally speaking, the sound quality of voice chips is related to two aspects. On the one hand, it is related to the hardware voice output bits of the voice itself. Generally, the output bits of the voice chip are 8BIT. The higher the 12bit and 16bit bits are, the better the sound quality is, the more delicate the voice will be. The lower the number of digits, the worse the sound. In general, 8bit can probably achieve the sound quality of a telephone, and 16bit can achieve the sound quality of a computer. On the one hand, the two bits are related to the voice decoding algorithm of the voice chip, which is equivalent to the MP3, WMA and CD audio quality.


The following four points need to be considered when selecting a voice chip:
2.1. Technology is critical
    Many people attach great importance to the use frequency of various excellent electronic components, which can achieve a very high use effect. On this basis, they can also get better use support. And when it comes to the selection of voice IC, it is very important to select a voice IC manufacturer with good production technology.


2.2. The effect should be stable
    The development of the times will drive progress in many fields. Now all kinds of voice products are produced and developed, and voice IC is also worth paying attention to. When it comes to the choice of voice ic, we should also choose a voice ic with stable technology. Only in this way can the stability of product functions be guaranteed.


2.3. Wide selection
    Considering the technical support provided by voice IC manufacturers, the outstanding performance will be improved a lot. It mentions the support of the application range. Voice chips can also play a role in the production of various voice products and improve the intelligence of the products, which deserves attention.


2.4. Guaranteed quality
    Professional voice IC manufacturers have a lot of technical support for the production of voice IC chips. This is a detail and content that cannot be ignored. It can bring good service quality, ensure the quality of voice IC chips, and meet the use needs of various industries. This is the reason for purchasing support.
