ASR Datasets Ptbr: Brazilian Portuguese Speech Corpora for Automatic Speech Recognition

A repository aggregating multiple public Brazilian Portuguese (PT-BR) speech corpora into a single dataset for Automatic Speech Recognition (ASR) training and research. The dataset was created by opedromartins and was last updated on 2025-09-14. Its goal is to provide a broad, standardized, and easily accessible resource for the community.

Use Cases

• Training Automatic Speech Recognition (ASR) models based on the aggregated Brazilian Portuguese audio.
• Benchmarking ASR system performance based on the standardized train/test/validation splits.
• Conducting linguistic or phonetic research on Brazilian Portuguese speech patterns based on the combined corpora.

Strengths

• Combines multiple public speech corpora, likely increasing diversity and scale.
• Provides standardized splits (train, test, validation) for consistent evaluation.
• Last updated on 2025-09-14, indicating recent maintenance.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count, file formats, and column-level documentation are absent.
• Data may reflect geographic or source bias inherent to the constituent public corpora.
