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 for modifying a string of text to human speech. It can read the text sent in UART connection. Built-in two languages, English and Spanish, and 9 different voices. It can be used, for example, in 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 detector with power voltage range from 3.5 to 5.5 V. The module is easy to use, it has three outputs: 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.

Sound sensor module with analog and digital output. It works with supply voltage from 3.3 V to 5.3 V. It allows you to detect the volume or the identification of characteristic sounds from the environment, for example clapping hands.
The module is equipped with an equalizer MSGEQ7. It allows you to add audio detection for Arduino sound. It has 7 frequency bands: 63 Hz, 160 Hz, 400 Hz, 1 kHz, 2.5 kHz, 6.25 kHz and 16 kHz. The module can be used to create a visualization of sound patterns in music or add audio activation to the microcontroller.
The module is based on the KA2284 system. It is used to measure the input signal with the 5 LEDs, which are gradually included depending on the value of the measured voltage. It can measure voltage AC or DC (selected using jumpers). Sensitivity is adjustable with a potentiometer. Works with voltages from 3.5 V to 12 V.
Microphone for use at home, with a frequency range from 40 Hz to 16 kHz. Equipped with a mini-tripod and a cable with plug, length 2 meters. It allows you to record human speech and the sound of the instruments, without distortion and noise.
Speaker powered from a USB port. It has connectors for headphones and microphone 3.5 mm, touch control panel. Speaker not only provides excellent sound quality, but also voice communication. Used as a sound source for laptops and computers, including the Raspberry Pi.
The module is equipped with electret microphone in the range from 20 Hz to 20 kHz and MAX4466 amplifier with automatic gain control. The intensity of the work in the amount of 2.4 V to 5 V. It has the ability to adjust the gain from 25x to 125x.
