This Grove speech recognizer module is designed explicitly for voice control applications such as smart homes, smart toys, voice control robots, or anything that we can control through voice. This board comes with an integrated Nuvoton ISD9160, a microphone, 1 SPI flash, 1 grove connector,1 speaker connector and 1 led to reflect your voice. Nuvoton ISD9160 was designed as an (SoC) Chipcorder based on Cortex-M0 running up to 50MHz. Thus provides a strong and economic solution for voice control applications. This low-power audio recording and playback module features embedded Flash and SRAM memory, real-time clock (RTC) control, and multiple general-purpose IOs (GPIOs). This ISD9160 chip allows the designers to develop systems and individual products providing clear, reliable, easily managed audio recording and playback. Moreover, the chip’s highly integrated architecture eliminates the need for various periphery chips.
The microphone present on the grove-speech recognizer is Omnidirectional. So that 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 supports about 22 pieces of commands including start, stop Play music, and so on. Every time when it recognizes a command or voice, it will return a value. And then the loudspeaker that is connected to the module will repeat the command. This value is further used to control other devices like a motor, music player. Moreover, these command voices possess a high recognition rate and a very low false trigger.
