Variation_Wizard and Gen_Vocab by Nerding and Hoarding 2026 Variation_Wizard An addon to the python_wizard that can generate LPC speech library to arduino. The Variation_wizard is a graphic interface windows program lets you generate many LPC variations of the same wave-file. The best version can then be used by Batch_Wizard to turn several wave-files into a speach library to run using Talkie on Arduino

User instructions Save your audio-clips for your Vocab Library in a folder. They must be .wav Mono 8000khz Signed 16-bit PCM. You can use Audacity for cutting and making wave from mp3. About 80-90 seconds total fits on Arduino Nano.

2. Click "01_Batch_Wizard_gui.py" Select your audio folder and name your txt file. (it is only a temporary file). Make adjustments to all the parameters.

3. Click "02_Gen_Vocab_gui.py" Name your vocal libray (YOURNAME). And find the txt file generated earlier. Click generate.

4. Open the talkie_YOURNAME.ino file in the talkie_YOURNAME folder and upload to your arduino board.

5. Start serial monitor at 115200. write number 1, 2 , 3 etc + ENTER to test the sounds in your vocab library.

6. To use your vocab in an arduino scetch you must have the YOURNAME.h and YOURNAME.cpp in the same folder as your arduino sketch (.ino file) write (#include "Talkie.h" #include "vocab_YOURNAME.h") at the top of your scetch. call the sounds voice.say(z_001);

Updates to base python_wizard Added "lpcplayer" package (based on talkie) to support Play feature in GUI. Added dirty support for other LPC coding tables. TMS5100 is default now.

    -T {tms5220,tms5100}, --tablesVariant {tms5220,tms5100}
                          Tables variant

Support for python formatted output

    -f {arduino,C,hex,python}, --outputFormat {arduino,C,hex,python}
                          Output file format

Small fixes and enhancements in GUI

This project is a python port of the great macOS tool BlueWizard (https://github.com/patrick99e99/BlueWizard), which is written in objective C and I was not familiar enough with this C dialect to make an portable command line application out of it. It is intended to convert (voice) audio streams into LPC bitstreams used in the TMS 5220 chip or e.g. in the Arduino library Talkie. Now you can generate your own LPC streams and make your chips say the things you want them to. Compared to BlueWizard some minor features have been added: Ability to downsample a wave file automatically Automated output formatters for C, Arduino (C-Dialect) and plain hex Prerequisites: Python 2.7 SciPy >= 0.18.1 Usage:
