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.
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.
WTV series voice chips manufactured by Waytronic company, with different models and functions, these chips can be controlled by key or serial port, support recording and playback of multiple voice, with different storage capacity and playback duration.
2, OTP voice chip refers to a one-time programming voice chip, it stores has been pre-programmed audio information, once programmed, these data can not 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. News broadcast: OTP voice chip can be used for broadcastingNotice, warning, or urgent notice.
3, the most popular words are used to control the sound and receive the sound. For example, the ic voice chip 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. The recordings are also processed to be stored on a memory chip.
4, in the big family of Speech chips, according to the type of sound can be divided into (Speech IC)And (Music IC) two kinds. This should be considered the voice chip professional distinction method. Mask production. In popular terms, mask production is to first burn the sound into the chip, and then package it, and there are generally quantity requirements. otp production. The so-called otp means a one-time burning. First we package the chip, then we use the software to burn the sound.
5, speech chip Speech chip definition: the speech signal is converted into a number by sampling, stored in the IC ROM, and then through the circuit to restore the numbers in the ROM into a speech signal. Ordinary voice chip playback function is essentially aMi 10 is the dream work of the 10th anniversary of Xiaomi mobile phone, and it is a performance flagship that breaks the limit. Not only has the new Snapdragon 865 processor, LPDDR5 memory UFS0 ultra-fast storage, super VC liquid cooling heat dissipation breaking the performance limit, but also dual-mode 5G network Wi-Fi 6 multi-network parallel, breaking the network limit. More customized 100 million pixel ultra HD four cameras, 90Hz high color precision flow screen, 8K ultra HD video, balanced stereo dual speakers to break the audio limit.
Step 1: Check that the phone's network connection Settings are turned on. Step 2: Disable WLAN Settings. Step 3:Select the setting of Access Point Name (APN) in Mobile Network Settings and set APN to CTNET for China Telecom Internet Settings. After the Settings are complete, check whether the mobile phone 3G network connection is normal. Step 4: If it still doesn't work, you can try to remove and reinsert the UIM card.
SONY K750, K550, two machines are about the same, K750 is a rocker, and it is an old model, the price is cheaper, within 1500, K550 is relatively new, about 1700, the two mobile phone photo effect is very good, sound quality is also very good, there are no other highlights, suitable for likeTake pictures of people to use.
