Portuguese (Brazil) General Conversation Speech Dataset

Welcome to the Brazilian Portuguese General Conversation Speech Dataset — a rich, linguistically diverse corpus purpose-built to accelerate the development of Portuguese speech technologies. This dataset is designed to train and fine-tune ASR systems, spoken language understanding models, and generative voice AI tailored to real-world Brazilian Portuguese communication.

Curated by FutureBeeAI, this 30 hours dataset offers unscripted, spontaneous two-speaker conversations across a wide array of real-life topics. It enables researchers, AI developers, and voice-first product teams to build robust, production-grade Portuguese speech models that understand and respond to authentic Brazilian accents and dialects.

The dataset comprises 30 hours of high-quality audio, featuring natural, free-flowing dialogue between native speakers of Brazilian Portuguese. These sessions range from informal daily talks to deeper, topic-specific discussions, ensuring variability and context richness for diverse use cases.

The dataset spans a wide variety of everyday and domain-relevant themes. This topic diversity ensures the resulting models are adaptable to broad speech contexts.

Each audio file is paired with a human-verified, verbatim transcription available in JSON format.

These transcriptions are production-ready, enabling seamless integration into ASR model pipelines or conversational AI workflows.

The dataset comes with granular metadata for both speakers and recordings:

Such metadata helps developers fine-tune model training and supports use-case-specific filtering or demographic analysis.

This dataset is a versatile resource for multiple Portuguese speech and language AI applications:

We continuously enrich this dataset with new, naturally captured conversations. Additionally, we support project-specific data customization:
