1. use iPhone App: Text to Speech
2. Export (email to self)
3. Use Zamzar (via browser) to convert to wav, or use https://audio.online-convert.com/convert-to-wav
4. Select 8 bit, 16,000Hz Sampling Rate, Mono channel, PCM unsigned 8 bit
5. Save to your files
6. Format the SD Card as FAT32
7. Copy voice recording into SD card
8. Safely eject SD card

Set up wiring

• Using breadboard pins 10-17 ( 17 - 5v, 15 - GND, 14 - CLK, 13 - DO, 12 - DI ,CS - 11
• Connect to Arduino ( VCC to 5v (17 on breadboard), GND to GND (15 on breadboard), 10 to CS (11 on breadboard), 13 to CLK (14 on breadboard), 11 to DI (12 on breadboard), 12 to DO (13 on breadboard)

New Direction: going to use Adafruit Wave Shield.

Steps

• Can use SD card, format to FAT32, use SD Formatter
• convert sound file to .wav uncompressed 22KHz 16bit (on a 12bit DAC), mono using https://audio.online-convert.com/convert-to-wav
