# OVOS - TTS Voice-Converted Mozilla Common Voice Scripted Speech v24.0 - Frisian Dataset

This dataset is a refined, processed version of the **Mozilla Common Voice (MCV) 24.0** Frisian (`fy-NL`) corpus, specifically curated for **Text-to-Speech (TTS)** training.

Unlike the raw ASR-focused Common Voice data, this version has been filtered for high-quality audio, normalized text, and formatted for modern TTS architectures like VITS, Glow-TTS, or YourTTS.

## Dataset Description
- **Language:** Frisian (fy-NL)
- **Source:** [Mozilla Common Voice Scripted Speech v24.0 - Frisian](https://datacollective.mozillafoundation.org/datasets/cmj8u3p4d008tnxxbxw3bkw70)
- **Format:** 24,000Hz Mono WAV
- **License:** [CC0 1.0 Universal](https://creativecommons.org/publicdomain/zero/1.0/)

## Processing Steps
To make this data suitable for TTS, the following pipeline was applied:
1. **Format conversion:** Conversion from mp3 to wav.
2. **Denoising:** Suppression of background noise and correction of distortion.
3. **Trimming:** Stripped silence from all clips.
4. **Normalization:** All audio intensity normalized.
5. **Outlier filtering:** Outliers filtered out in terms of unusual words per minute.
6. **Voice conversion:** Conversion of speaker features in the audio to a donated voice (to OVOS).

## Dataset Structure
The dataset follows a standard metadata format:
* `file_name`: The audio file path or array.
* `transcript`: The normalized transcript for TTS.

An alternative metadata file is provided with the original Mozilla Common Voice metadata.

## Licensing
Consistent with the [Mozilla Common Voice Legal Terms](https://commonvoice.mozilla.org/en/terms), this dataset is released under the **Creative Commons CC0 1.0 Universal (Public Domain)** license. You may use, modify, and distribute this data without restriction.
