Motivation for Thorsten-Voice project 🗣️ 💬
A free to use, offline working, high quality german TTS voice should be available for every project without any license struggling.
Some personal words before using Thorsten-Voice
I contribute my voice as a person believing in a world where all people are equal. No matter of gender, sexual orientation, religion, skin color and geocoordinates of birth location. A global world where everybody is warmly welcome on any place on this planet and open and free knowledge and education is available to everyone. 🌍 (Thorsten Müller)
Please keep in mind, that i am no professional voice talent. I'm just a normal guy sharing his voice with the world.

Dataset evolution
As described in the PDF document (evolution of thorsten dataset) this dataset consists of three recording phases.
- Phase 1: Recorded with a cheap usb microphone (low quality)
- Phase 2: Recorded with a good microphone (good quality)
- Phase 3: Recorded with same good microphone but longer phrases (> 100 chars) (good quality)
If you want to use a dataset subset you can see which files belong to which recording phase in recording quality csv file.

All emotional recordings where recorded by myself and i tried to feel and pronounce that emotion even if the phrase context does not match that emotion. Example: I pronounced the sleepy recordings in the tone i have shortly before falling asleep.

Other models
Silero
You can use a free A-GPL licensed models trained on Thorsten-21.02-neutral dataset via the silero-models project.
ZDisket
ZDisket made a tool called TensorVox for setting up an TTS environment on Windows and included a german TTS model trained by monatis. Thanks for sharing that 👍. See it in action on Youtube.
Public talks
I really want to bring the topic "Open Voice For An Open Future" to a bigger public attention.
- I've been part of a Linux User Group podcast about Mycroft AI and talked on my TTS efforts on that in (May 2021).
- I was invited by Yusuf from Turkish tensorflow community to talk on "How to make machines speak with your own voice". This talk has been streamed live on Youtube and is available here. If you're interested on the showed slides, feel free to download my presentation here (June 2021) )
- I've been invited as speaker on VoiceLunch language & linguistics on 03.01.2022. Here are my slides (January 2022).
Youtube channel
In summer 2021 i've started to share my lessons learned and experiences on open voice tech, in special TTS on my little Youtube channel. If you check out and like my videos i'd happy to welcome you as subscriber and member of my little Youtube community.
Feel free to file an issue if you ...
- Use my TTS voice in your project(s)
- Want to share your trained "Thorsten" model
- Get to know about any abuse usage of my voice
Thanks section
Cool projects
Cool people
Even more special people
Additionally, a really nice thanks for my dear colleague, Sebastian Kraus, for supporting me with audio recording equipment and for being the creative mastermind behind the logo design.
And last but not least i want to say a huge, huge thank you to a special guy who supported me on this journey as a partner right from the beginning. Not just with nice words, but with his time, audio optimization knowhow and finally GPU power.
Thank you so much, dear Dominik (@domcross) for being my partner on this journey.
