Issues

TTS Engine

TTS Engines available

• https://mimic.mycroft.ai/
• https://www.knowledgenile.com/blogs/open-source-tts-engine/

Espeak-NG

Espeak-NG works out of the box, but the voice is quite robotic and it seems to "chew" the words.

Possible solutions:

• use Mbrola voices
  The installation does not appear straight-forward.

Button Test

Try one of the many tutorials. Example: https://www.makeuseof.com/tag/add-button-raspberry-pi-project/ Usually they involve an LED, but you can skip it.

Steps:

1. On your main pc, copy the file raspberry_test_button.py over to the Raspberry Pi
   scp raspberry_test_joke.py pi@[RASPBERRYPI IP]:/home/pi/
2. Run the file raspberry_test_button.py
python3 raspberry_test_button.py

Make sure that when the button is pressed, the output prints the proper result.

Dial-A-Joke Test

Steps:

1. Install pyttsx3 with pip3 install pyttsx3
2. On your main pc, copy the file raspberry_test_joke.py over to the Raspberry Pi
   scp raspberry_test_joke.py pi@[RASPBERRYPI IP]:/home/pi/
3. Connect the hearphones to the Raspberry Pi
4. Run the file raspberry_test_joke.py
python3 raspberry_test_joke.py

Make sure that when the button is pressed, you can hear a joke through the hearphones.
