 #### Introductory round
 
 #### Data Requirements
+
 - Speech Freqs 16 - 24 kHz, Input for Tokenizer
 - Ideally dataset would be paired, even more ideal including speaker annotations and dialect labels
-- Goal: ~ 20k hours audio data, not only Swiss German
+- Goal: \~ 20k hours audio data, not only Swiss German
 - Audio of all European languages will be included
 - Ideally openly available, like hugging face
 - Data should be reproducible / versioned
-- Data needs to be available online at model release -> reproducibility
+- Data needs to be available online at model release -\> reproducibility
 - SRF quality should be good enough
 - All Swiss Languages from SRG are welcome
 
 Re licencing (stressed by Immanol):
+
 - The model does not memorize (due to Goldfish loss)
 - Hence the model is not a derivative of the data
 - Due to lack of memorization, license constraints of data do not need to apply for the models

 - Model generation will be restricted to text, no audio, no images
 
 #### Possible Sources Roberto
+
 - Roberto: SRG could provide own production data, not all data
 - Apertus: Open for other data sources
 - Synthesized data could be helpful as well
 
 #### Processing steps

 - speaker tags
 - transcriptions
 - de-duplication

 #### Infrastructure

 - Clariden can be used
 - Ultimately, codes should be available through Swiss AI GitHub, now FHNW GitLab is ok
 
 #### Timeline / Roadmap

 - Tokenizer identification up next
