At present, the voice chip and voice module available in the market can be selected according to the length of time and function. The following is some experience, hoping to be helpful to users who use voice chip for the first time.
L Considering the length of time:
Generally, the duration of voice chip (default OTP: one-time) is 6~340 seconds. Basically focused on short seconds. It has clear sound, short time, low price, easy production, and unlimited order quantity, so it is a better choice for product testing. The price of 20 second chips on the market is about 2~3 yuan; About 4-5 yuan in 40 seconds; 170 seconds is about 9~10 yuan. In general, the manufacturer makes samples. When the user orders for service, the manufacturer burns the contents and gives them to the user. In this way, users can save some time. If the user's voice needs to be modified frequently, he can buy a set of programming (also called a burner, a downloader), learn how to make it himself, and then he can make it himself. The voice chip is mainly used in security access control, household appliances, medical equipment and other occasions.
OTP voice chip is a programmable one-time voice chip, which cannot be burned repeatedly. At present, our company's OTP voice chip There are WTN6 series (many commonly used voice chips in the market at present have high cost performance and sound quality WTN6 series voice chip ）。
The storage capacity of the external flash voice chip is much larger than that of the OTP voice chip, and the audio content can be replaced repeatedly. At present, our external flash voice chips include WTV600 mixer chip, WT2000H high-quality chip, WT2003H series MP3 chip, and WT2605 high-quality MP3 decoding chip series.
The structure of the voice module is about MCU+external memory, so its storage capacity is much larger than that of the chip, from 10 to 30 minutes. However, the price generally ranges from 20 to 80 yuan, several times that of the chip. The size is also larger than the chip, and the power consumption is slightly larger.
Voice module It integrates the voice chip with the peripheral circuit, and can be used without adding additional devices; At present, our voice modules include WT2003H series and WT2605 series.
L In terms of function:
OTP voice chips are disposable. They can be ordered in any quantity and shipped quickly, but they also have disadvantages: they cannot be burned and written repeatedly. Our company has produced some voice modules that can be rewritten repeatedly, such as WT588F series voice module, WT2003H series voice module WT2605 series voice modules, some of which can be replaced by MCU or supporting burners, some can be replaced by voice content directly through USB port, and even can be downloaded remotely for voice updates. These powerful functions greatly enrich the connotation of voice modules, increase their application fields, and open up new horizons.
With the development of technology and the integration of products, voice chips have gradually replaced a variety of voice devices in various applications. The main characteristics of voice chips are low power consumption, strong anti-interference ability, few peripheral devices, simple control, long voice storage time (some voice chips can store content for 100 years), no loss of voice when power is off, and some chips can repeatedly erase voice content. Such as car reversing radar, electronic lock, treadmill, rice cooker, anti-theft system and other equipment are equipped with voice chips. As there are many kinds of chips with different functions, engineers will have some hesitation in selecting voice chips. Therefore, engineers who are new to the voice industry will be provided with some reference for selecting voice chips.

At present, with the popularization of AI AI concept, product innovation needs , Speech recognition scheme The application is also closer to daily life. The intelligent module is divided into two categories: voice recognition module and MP3 audio Bluetooth module; At present, our company's speech recognition chips include WTK6900F series and WTK6900G series. The speech recognition modules mainly include WTK6900F-B03, WTK6900G-B01, WTK6900H series, etc. It is a non-specific speech recognition scheme, the terms can be customized, and the special speech recognition scheme for the lighting industry is WTK6900F series; Bluetooth module mainly includes WT2605 Audio Bluetooth module Series.

We hope it can help you understand our industry in the selection. If you are not sure how to select a model, you can consult our online engineers to sincerely provide you with a voice solution that is suitable for you and solve your problems with voice chip options.
FAQ:
1. Excuse me, I need to use very little voice content. In a few words, what type of voice chip should I choose?
A: Hello, if you don't have much demand for voice content, you can choose OTP voice chips from Shenzhen Weichuang Zhiyin Electronics Co., Ltd. You can recommend WTN6 series.
2. Because this is the first time I have access to a voice chip, I want to ask, what should I do to input the voice chip I want into the chip?
Answer:; Hello, the service of voice chip of Shenzhen Weichuang Zhiyin Electronics Co., Ltd. is roughly as follows: First, you can send us the voice content you need, which can be in written form (of course, it is better if you have a ready made voice). Then we will recommend a suitable voice chip according to your functional requirements, and then burn the voice content you need to use into the chip according to your requirements. Customers only need to send the corresponding instructions with the microcontroller to let the chip play the voice. If you want to burn your own different voice content into the chip, it is also possible. First, you can select a voice chip from Shenzhen Weichuang Zhiyin Electronics Co., Ltd., and then we will send you a supporting host computer software. Then you can operate according to the software's instruction manual to generate a burning document, and then use the download tool from Shenzhen Weichuang Zhiyin Electronics Co., Ltd. to burn the burning document into the chip, Then send the corresponding instructions to the chip to play the sound.
3. Hello, this is my first time to contact a voice chip. I want to know how to choose a suitable voice chip?
A: Hello, generally speaking, voice chips are chosen because voice related functions may be required in the product. First, you can choose a voice chip according to the capacity of your voice content. For example, if the required voice content is about tens of seconds, you can choose the OTP class of Shenzhen Weichuang Zhiyin Electronics Co., Ltd., such as the WTN6 series. For another example, if you need voice content, it may take several minutes, or even dozens of minutes. You can choose Shenzhen Weichuang Zhiyin Electronics Co., Ltd.'s repeatable erasable type, such as WT588F or WT2003H series; If you need to play different voice content for several hours, even days, or months, you can consider choosing WT2003H series from Shenzhen Weichuang Zhiyin Electronics Co., Ltd.
