A system for translating a puppet show script to a real time control of a complete robotic puppet theatre show

Areas of control - mouth movement. single servo Additional motion - stage and curtain control

components of system

1- A Libreoffice spreadsheet template to write out the script and sequences of the theatre play 2- pysimplegui User interface for setting up the script 3- output of controls for ESP32 - for preloading on ESP32

use pyserial for real time control (in the first version this is not used). or use subsystem call to load the file using the arduino ide.

Use UDP multicast to start / pause / stop the script on all the ESP32s in sync.

Convert the text to International Phonetics using the english-to-ipa library then convert the phonetics symbols to motor movements.

Nuances of system.

Words - some "basic" words are programmed in as canned cycles letters - all other words are programmed in as individual letters

an interesting project with 13 servos that is open source http://keenbots.com/Fritz/gallery.php

https://aws.amazon.com/polly/ - text to speech. supports lexicons and SSML

expressions - each line of text can have an associated expression awkward neutral sinister sleepy sneaky sulk calm happy sad angry fearful surprised careful subtle disgusted whisper

laughing crying sneezing

SSML tags for the TTS:

break emphasis 1-3 pause breathing sound softly timbre

prosody: strength - 1-6 rate 1-5 pitch 1-5 volume 1-6

in the user interface allow up to 5 parallel threads for robots and curtain motor controls The user interface for compiling the Puppet script is in a LibreOffice Template for now

Select the voice for the puppet (from the Amazon list, currently limited to English)

For each line you can set the prosody, and other SSML nuances for each robot. this is also reflected in the way the mouth moves.

Once the script is ready. Save it as a CSV file.

Open the TheatreProcessing.exe or py file.

Import the CSV file

Then click to process it. The processing does the following:

1- Converts the text to IPA

2- Upload to the Text to speech system and retrieves the audio file

3- Converts the IPA text to individual motor movements for the robot mouths / stages / curtains

4- uploads the Code to the ESP-32 controllers

Once the processing is complete the theatre can be "started". Starting sends a signal by Multicast to all the ESP32s as well as beginning the Audio Playback on the computer.

This Python program utilizes the Carnegie-Mellon University Pronouncing Dictionary to convert English text into the International Phonetic Alphabet.
