Thorsten-Voice TV-24kHz-Neutral-tokenised

Overview

This dataset is a tokenised German text-to-speech dataset created for training and fine-tuning the Orpheus TTS model family.

It is based on approximately 12,000 speech recordings from the original Thorsten-Voice Dataset (2022.10) and has been resampled to 24 kHz and tokenised using Orpheus TTS preprocessing.

This dataset is intended for:

Training and fine-tuning Orpheus-based German TTS models
Research on neural speech synthesis
Open, unrestricted TTS experimentation

Dataset Origin

Original dataset: Thorsten-Voice Dataset 2022.10
DOI: https://doi.org/10.5281/zenodo.7265581
Language: German (de)
Speaker: Thorsten (single speaker)

All audio originates from the original Thorsten-Voice corpus and was reprocessed for compatibility with Orpheus TTS.

Processing Details

Audio resampled to 24,000 Hz
Loudness normalized to -24dB
Tokenised using the Orpheus TTS tokenizer jupyter notebook (huggingface dataset package < 4)
Stored as a tokenised dataset ready for training

The tokenisation reflects the Orpheus TTS codebase as of December 2025. Jupyter notebook used to tokenize is attached to this dataset (see files). Thanks to OrpheusTTS for providing.
