AI on the Edge LESSON 9: Make Your Raspberry Pi Talk with TTS

In this video lesson I show you how to make your Pi Project talk to you using Text to Speech (TTS). We will use the Piper Model which gives good clear voice, and a choice from a large number of different models.

In this lesson I show you my solution to the Homework assigned in LESSON #8.

In this lesson we demonstrate this program, which makes the Pi talk, through the Fusion HAT+ speaker. The homework was to create a program that smoothly adjust the brightness of an LED using a potentiometer. The project was also to speak to the user, indicating what brightness the LED was set at.

This is the schematic we are using on these projects;

Fusion Hat Circuit Diagram — This is the circuit we will use moving forward in the class

This Schematic is explained in detail in LESSON #5.

Then this is the code we developed in today’s lesson.

from fusion_hat.pwm import PWM
from fusion_hat.tts import Piper

tts = Piper()
tts.set_model('en_US-amy-low')

myPot = ADC(potPin)
redPin = 5
redLED = PWM(redPin)
rangeOld = 100

while True:
    potVal = myPot.read()
    writeVal=100*(potVal/4095) - .005
    if writeVal < 1:
        msg = "Your LED is Off"
        range = 0
    if writeVal >=1 and writeVal<10:
