Grove - Speech Recognizer
Use voice to interact with things around you can always be one of the most interesting
things of IoT application, we want to make something more different and cooler.
Recently we just launched the voice control solution Respeaker on Kickstarter and it
becomes the blockbuster. However not everybody needs a Respeaker to build voice
control project, sometimes people only need a simple solution, here we would like to
introduce the first generation of grove speech recognizer to realize your dream of smart
home easily and fast.
Grove 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 (SoC) Chipcorder that based on Cortex-M0, it provides strong
and economic solution for voice control applications. ISD9160 is not the only amazing
thing in this grove. Lets 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 wont 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 recognize the command word, LED will turn blue.
Note
The firmware of the module was wrote by the third party vendor, it's not open source.
