Grove speech recognizer is based on Cortex™-M0. It is a designed for voice control application such as smart home, smart toy, voice control robot, anything you would like to control through voice, it worth a try.FeaturesExcellent and powerful SoC: The Cortex-M0 provides powerful performance, processing speed up to 50MHz. Ensures high recognition rate and very low false trigger rate.Built-in omni-directional microphone: No matter what direction you speak into the microphone, the microphone will record the signals all with equal gain.22 recognition entry: Including ＇start＇, ＇stop＇, ＇Play music＇ and so on.Grove unified socket: The product ensures ＂Plug and Play＂ and could be versatile for various applications.DescriptionGrove speech recognizer is a designed for voice control application such as smart home, smart toy, voice control robot, anything you would like to control through voice, it worth a try. The board includes a Nuvoton ISD9160, a microphone, 1 SPI flash, 1 grove connector,1 speaker connector and 1 led to reflect to your voice.Nuvoton ISD9160 is a system-on-chip product optimized for low power, audio record and playback with an embedded ARM® Cortex™-M0 32-bit microcontroller core. It provides strong and economic solution for voice control applications. ISD9160 is not the only amazing thing in this grove. Let’s look at the microphone. Remember the uncomfortable moment when you have to speak directly and closely to the voice recognizer device to make sure it can hear you? It won’t happen this time! The microphone on grove-speech recognizer is Omni-directional, which means that whether a user speaks into the microphone from the front, back, left or right side, the microphone will record the signals all with equal gain.This speech recognizer can recognize 22 pieces of commands including ＇start＇, ＇stop＇, ＇Play music＇ and so on. Every time it recognizes a command, it will return a value and then the loudspeaker that connected to it will repeat the command. This value can be used to control other devices like motor, music player. We have tested it for hours to make sure it possesses a high recognition rate and a very low false trigger.Here are some notes that you must know before using it: Awaken Word: Hicell (Please pronounce it as one word) When it recognizes the awaken word, LED turn red, then you can say the command word, if it recognizes the command word, LED will turn blue.NoteThe package does not include speaker.We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs.
