This shield was designed around the RC System Text To Speech Chip Set:
"The RC8650/60 chipsets include everything needed to implement text-to-speech synthesis with full dynamic control of the voice characteristics. In addition, integrated tone generators provide telephone dialing, music, and programmable signaling tones. Up to 7.5 MB of built in, flash-based recording memory can store up to 33 minutes of sound files, which can be played back on demand."
The Shield also carries a TB6621FNG Dual Motor Speed Controller, A 1 Watt Amp for the Robots Voice and an extra 5V regulator for extra Servo Current.
Now your robot project can come to life with one simple-to-use roboShield.

– NEW...Use of PCA9685 for PWM!
– High voice quality, unlimited vocabulary
– Converts any ASCII text into speech automatically
– Capable of very high reading rates
– Add/modify messages by simply editing a text file
I just redesigned the schematic today to free up many of the IO pins on the Arduino. The PC9685 will take care of all the PWM and IO pins needed to run the Motor Controller chip and 6 servos! The Arduino is notorious for messing with a servo PWM while using the softwareSerial library (needed to send the voice messages to the text to speech converter).
