6 Solid State Voice Recorder Using Flash MSP430 The digital hardware is the MSP430F149 flash microcontroller and its associated passive components. Reference [1] is the datasheet for this device. The integrated peripherals simplify the digital design and this application is a good example for MSP430 being a “System in a Chip.”

The knowles part is a great part (though a little pricey, since it is designed for hearing aids), but really I wouldn't use it for this project, although the frequency response curve is shown as flat, these parts are really designed for hearing aids and telecomms, where the operating frequency range is from 100Hz to 3400Hz, and there low frequency response is not …

The recorded sound can then be stored in memory (flash or RAM). A button press can trigger the MCU to play the recorded sound. To play the sound, software moves the stored data to a digital-to-analog converter (DAC) followed by an audio power amplifier. Such a sound recorder can be easily realized using the MSP430 MCUs. The MSP430 MCU takes
MSP430 to record I2S (or PWM) data streams - MSP low-power ...

Depending on the time you like to record, an external buffer might be a way to do. Be aware that SDcards are not fast writing media. By the way, have you considered to use analog mics and convert it directly with MSP430's A/D converter. Attach the MSP430 at mic and you have no interference issue (at least no EMI).
How can I record audio with the ADC12? - MSP low-power ...
https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/338670?How-can-I-record-audio-with-the-ADC12-
So I am trying to record audio with my MSP430F5529 through the ADC12. The code I have so far is attached below. I am basically storing information from ADCMEM0 into an array called results. The size of this array is 4000 because anything longer will give the error: "#10099-D program will not fit into available memory.

To do voice recognition you don't need to **record** voice in tape or voice recorder, you need that your microcontroller is able to record voice and do voice recognition alone. Actually I highly doubt that msp430 is good for your application because voice recognition is CPU-intensive task. Msp430 is not that powerful uC.

The following figure shows the pinout diagram of the Voice Recorder and Playback Module based on ISD1760 IC. +5V and GND pins are used to power up the module. It can also be power up from a Connector plugin black color. A MIC is available for recording and SP+ and SP- pins are used to connect the external speaker to hear recorded voice notes.
