This individual thinks best. There are Lingyang, Lingtong such chip manufacturers, there are also many secondary development companies like Chengxin Sheng Silicon Jietong! Not bad, too.
3, the launch of JQ2660 voice MCU, very forward-looking and revolutionary voice market, is bound to roll up a whirlwind in the application of voice chips. How to use JQ2660 voice microcontroller in practical applicationTo the incisive, you also need to read the JQ2660 series voice microcontroller instruction manual. Finally, thank you for choosing JQ2660 series voice MCU as the core of the voice circuit.
4, NVD series voice chip has a variety of key trigger mode, and can output a variety of forms of level signals, can be set according to the fluctuation of the rhythm of voice change.
5, the ISD1420 voice chip may be able to solve your problem. The ISD1420 can be recorded/played in segments, up to 160 segments, and the maximum recording time is 20 seconds. The I/O pin of the single chip microcomputerThe connection with the voice segment address of the voice chip can realize the programmable output of the voice by changing the voice segment address, and of course, it can also record/play the voice for 20 seconds continuously without segments.
1, WTV series voice chip, SYN6288 voice 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 a serial port to record and play multiple voice segments.Has different storage capacity and playback duration.
2, ICRoute company's LD3320, a non-specific person's speech recognition chip, the MCU can pass the Chinese pinyin string identification words to LD3320 by reading and writing registers, start speech recognition work. This individual thinks best. There are Lingyang, Lingtong such chip manufacturers, there are also many secondary development companies like Chengxin Sheng Silicon Jietong! Not bad, too.
3, CI1102 or CI1103, our single mai local speech recognition compatible module is used by the CI110It is a neural network processor (BNPU) that supports speech detection, speech recognition, voice print recognition, and dual microphone speech processing. Operating frequency 160MHz, support single mai far field noise reduction.
4, NVD series voice chip has a variety of key trigger mode, and can output a variety of forms of level signals, can be set according to the fluctuation of the rhythm of voice change.
1, phonetic recognitionSpecific 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 needs. 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.
2, 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). In addition, the voice recognition chip also hasIt has the function of high quality and high compression rate recording and playback, which can realize man-machine dialogue.
3, the main features of the voice chip are low power consumption, strong anti-interference ability, fewer peripheral devices, simple control, long voice storage time (some voice chips can save the content for 100 years), no loss of voice after power failure, some chips can also repeatedly erase and write the voice content. Such as car reversing radar, bus stopping device, bank queue machine, voice toys, anti-theft system and other equipment are equipped with voice chips.
This, you can look at the KT404A or KT403A chip scheme, this is much better than the ordinary OTP voice chip, the sound quality is very good, voice download directly through the usb interface of the chip, no need to host computer software, support tf card or u disk and other external devices. 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 increased with external SPIFlash.
WTV series voice chip, SYN6288 voice synthesis chip, etc. The WTV series voice chips are manufactured by WayProduced by tronic, with 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.
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.
1, use WT588D voice chip. WT588D is a commonly used voice chip, which can be used with 51 single chip microcomputer to realize voice broadcasting function. In the design of bus station announcement system, WT588D can be used as recording module, which is controlled by 51 MCU to play different voice files.
2, you can use the speech recognition chip LD3320, circuit diagram you can know as long as under its pdf, pdf which has a typical application. But I recommend you not to use this chip, for comparisonIt's around 100 yuan. I recommend you to use the Sun 61 microcontroller, with its own voice recognition module, designed for speech. And the official provides many functions, you can call directly, do not need to write their own programs to control the intermediate processing of sound.
3, WTV series voice chip by Waytronic company production, with different models and functions, these chips can be controlled by key or serial port control, support recording and playback of multiple voice, with different storage capacity and playback time.
4, DSP is the core of the Harvard bus structure is the multiplier and adderMCU is von Neumann structure, the core is the ALU DSP chip, also known as the digital signal processor, is a kind of microprocessor especially suitable for digital signal processing operations, its host application is to quickly realize a variety of digital signal processing algorithms in real time.
5, the question is not clear. There are many voice chip models, most of which can handle multiple voice messages, so in principle they can be controlled by 51. Because the voice chip is actually a voice memory chip, so each message segment must have an address code, if you want to play which voice, use 51 to call this address,You can play voice.
