-# Introduction
+![Thorsten-Voice logo](Logo_Thorsten-Voice.png)
-Many smart voice assistants like Amazon Alexa, Google Home, Apple Siri and Microsoft Cortana use cloud services to offer their (base) functionality.
 
-As some people have privacy concerns using these services there are some (open source) projects trying to build offline and/or privacy aware alternatives.
+- [Project motivation](#motivation-for-thorsten-voice-project-speaking_head-speech_balloon)
+  
+- [Personal note](#some-personal-words-before-using-thorsten-voice)
 
-But speech recognition and text synthesis still requires cloud services for providing these in a decent quality.

-MyCroft is a company developing an opensource voice assistant with a very nice and active community. But the stt/tts parts are still cloud based (eg. google services), even if requests are anonymized by a mycroft proxy in between. But integration with locally hosted services such as deepspeech (stt) or mimic/tacotron (tts) is possible.

+- [Special Thanks](#thanks-section)
-Mozilla works on these really important aspects for free and open human machine voice interaction.
-
-## STT - speech to text
-> https://commonvoice.mozilla.org/
-
-"STT" needs lots of audio training data by many speakers (women/men/kids) of all ages, dialects and in various audio quality levels. So any voice contribution for common voice project is highly welcome.
-
-## TTS - text to speech
-> https://github.com/mozilla/tts
-
-"TTS" needs lots of clean recordings by one speaker to train a model. Mozilla is developing a software stack for proper model training based on tacotron2 papers.
-
-# And?!
-I want to make the most personal contribution i can give and contribute my personal voice (**german**) for TTS training to the community for free usage.
-
-## Please read some personal words before downloading the dataset
-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.
-
-So hopefully my voice is used in this manner to make this world a better place for all of us :-).
-
-**tl;dr** Please don't use for evil!

-# Dataset "thorsten"
-## Samples of my voice
-To get an impression what my voice sounds to decide if it fits to your project i published some sample recordings, so no need to download complete dataset first.

+As described in the PDF document ([evolution of thorsten dataset](./EvolutionOfThorstenDataset.pdf)) 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](./RecordingQuality.csv) csv file.

+### ZDisket
+[ZDisket](https://github.com/ZDisket/TensorVox) made a tool called TensorVox for setting up an TTS environment on Windows and included a german TTS model trained by [monatis](https://github.com/monatis/german-tts).

+
+# 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](https://github.com/monatis/) 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](https://www.youtube.com/watch?v=m-Uwb-Bg144&t=2303s). If you're interested on the showed slides, feel free to download my presentation [here](https://docs.google.com/presentation/d/1ynnw0ilKV3WwMSJHytrN3GXRiFr8x3r0DUimBm1y0LI/edit?usp=sharing) (*June 2021*)

+# Vocoder Vergleich auf Basis des "thorsten" Tacotron 2 Modells
+Hier sind Hörproben mit unterschiedlichen Vocodern. Alle gesprochenen Texte (*Sample 1 - 4*) basieren auf Aufnahmen im Dataset, jedoch nicht auf dem Spektogramm von "ground truth", sondern auf Basis des trainierten Tacotron 2 Modells. Sample 5 ist der Beginn des Märchens "Der Froschkönig" und wurde nicht für das Dataset aufgezeichnet.
+
+## Sätze
+* **Sample #01**: Eure Schoko-Bonbons sind sagenhaft lecker!
+* **Sample #02**: Eure Tröte nervt.
+* **Sample #03**: Europa und Asien zusammengenommen wird auch als Eurasien bezeichnet.
+* **Sample #04**: Euer Plan hat ja toll geklappt.
+* *Sample #05: "In den alten Zeiten, wo das Wünschen noch geholfen hat, lebte ein König, dessen Töchter waren alle schön." (Anfang vom "Froschkönig")*

+# v1.2  - Added choice for choosing which recording session should be exported as LJSpeech
+# v1.3  - Added parameter mrs_dir to pass directory of Mimic-Recording-Studio
+# v1.4  - Script won't crash when audio recorded has been deleted on disk
+# v1.5  - Added parameter "ffmpeg" to make converting with ffmpeg optional

+
+## MRS2LJSpeech
+Python script which takes recordings (filesystem and sqlite db) done with Mycroft Mimic-Recording-Studio (https://github.com/MycroftAI/mimic-recording-studio) and creates an audio optimized dataset in widely supported LJSpeech directory structure.
+
+Peter Schmalfeldt (https://github.com/manifestinteractive) did an amazing job as he optimized my originally (quick'n dirty) version of that script, so thank you Peter :-)
+See more details here: https://gist.github.com/manifestinteractive/6fd9be62d0ede934d4e1171e5e751aba#file-mrs2ljspeech-py

+## Dockerfile.Jetson-Coqui
+> Add your user to `docker` group to not require sudo on all operations.
+
+Thanks to NVIDIA for providing docker images for Jetson platform. I use the "machine learning (ML)" image as baseimage for setting up a Coqui environment.
+
+> You can use any branch or tag as COQUI_BRANCH argument. v0.1.3 is just the current stable version.
+
+Switch to directory where Dockerfile is in and run `nvidia-docker build . -f Dockerfile.Jetson-Coqui --build-arg COQUI_BRANCH=v0.1.3 -t jetson-coqui` to build your container image. When build process is finished you can start a container on that image.
+
+
+### Mapped volumes
+We need to bring your dataset and configuration file into our container so we should map a volume on running container
+`nvidia-docker run -p 8888:8888 -d --shm-size 32g --gpus all -v [host path with dataset and config.json]:/coqui/TTS/data jetson-coqui`. Now we have a running container ready for Coqui TTS magic.
+
+### Jupyter notebook
+Coqui provides lots of useful Jupyter notebooks for dataset analysis. Once your container is up and running you should be able to call 
+
+### Running bash into container
+`nvidia-docker exec -it jetson-coqui /bin/bash` now you're inside the container and an `ls /coqui/TTS/data` should show your dataset files.
