The module is equipped with electret microphone in the range from 20 Hz to 20 kHz and the amplifier MAX9814 with auto gain control. The intensity of the work in the amount of 2.7 V to 5.5 V. the Maximum gain-60 dB.
Module with silicon microphone, MEMS type, which does not require amplifier. It detects sound with frequency from 100 Hz to 10 kHz and converts it into an analog output signal that can be read using the A/D converter. The device operates with a voltage from 3.3 V to 5 V.
Synthesizer by modifying a string of text to human speech. Can read the text sent in connection UART. Built-in two languages, English and Spanish, and 9 different voices. Given, for example, the construction of a talking robot.
This project shows how to start the recognition of a natural language and how to link it with Google Assistant using a voice set AIY Projects. To everything that Google Assistant do, you can add your own questions and answers. All is closed in a small, cardboard cube powered by Raspberry Pi.
Audio detection, power voltage range from 3.5 to 5.5 V. the Module is easy to use, has three outputs: an analog - to measure the intensity of the signal, digital is changing the state when exceeding a certain level and the audio output. The module has a soldered connector.
