YodaLingua-Portuguese

YodaLingua is a high-quality speech dataset designed for training text-to-speech (TTS) systems, ASR models, and any application requiring clean, well-aligned audio–text pairs.
This release contains the Portuguese portion of the multilingual YodaLingua collection.

Data Fields

Each entry in the dataset contains the following fields:

Field	Description
__key__	Unique identifier for each sample.
audio	Path to the audio file associated with the sample (MP3 format).
text	Ground-truth transcription of the audio segment.
language	Language code following ISO 639 standards.
speaker_id	Unique identifier assigned to each speaker. Multiple audio can share the same speaker ID.
dnsmos	DNSMOS P.835 Overall (OVRL) score estimating perceptual speech quality; higher values indicate cleaner and more intelligible audio.

We apply a multi-stage pipeline to ensure maximum data quality:

1. Standardization

• Convert to WAV
• Mono channel
• Resample to 24 kHz
• 16-bit sample width
• Normalize to –20 dBFS (with volume correction between –3 and +3 dB)

2. Noise Reduction

Advanced denoising applied to improve clarity and remove background artifacts.

3. Speaker Diarization

Segment long recordings by speaker to improve diversity and ensure speaker-consistent utterances.

4. Voice Activity Detection (VAD)

Merge consecutive VAD segments from the same speaker into clean utterances of 3–30 s.

5. Transcription

State-of-the-art ASR models produce accurate text transcripts.

6. Quality Filtering

Clips are filtered using DNSMOS P.835 OVRL; only samples with a score > 3.0 are retained.
