You collect the ADC digitized voice of all possible vocabulary that you might need, analyze and compress them, stored the compressed data in the MSP430 Flash, and write a MSP program to look up into the table, decompress them and use DAC or PWM to generate the signal to drive an audio amplifier. It is not difficult but rather tedious to do.

Low-Cost Speech With MSP430™ MCUs 3 Audio Playback For audio playback, a digital-to-analog conversion is necessary. An alternative to using the MSP430's DAC12 is using PWM output with a timer. Both solutions have advantages and disadvantages. 3.1 Audio Playback With DAC12 Using the DAC12 is the straight-forward solution.

I'm trying to develop a function that will output 300 baud AFSK from the speaker on the MSP430 experimenter board. I want to transmit binary data from the speaker on the experimenter board through the mic on a standard telephone. I have reviewed the application note for the V.21 softmodem (slaa204 ...

to use the MSP430™ on-chip analog voltage comparator with an internal reference digital-to-analog converter (DAC) to measure the voltage then output PWM signals. This has been optimized for lowest code size, fitting in MSP430FR2000 MCU, which contains 512 bytes of main memory. To get started, download project files and a code example demonstrating this
