Spanish Full-Duplex Conversation Dataset

Marketplace

Two-speaker Spanish conversations spanning Latin American and European dialects, captured in stereo full-duplex with natural overlap.

Overview

Naturalistic, two-speaker Spanish conversations captured at studio quality in full-duplex stereo. Pairs of native Spanish speakers from Spain, Mexico, Colombia, Argentina, and other Latin American regions discuss everyday topics for the full duration of the session — no read scripts, no scene cuts. Each recording preserves real overlapping speech, backchannels, hesitations, and code-switching, so downstream models train on the way Spanish actually sounds in the wild. Every clip is collected from paid contributors with explicit consent, scene-level provenance, and metadata for speaker demographics, dialect, and acoustic environment.

Key highlights

  • 01

    Castilian Spain, Mexican, Colombian, and Argentinian Spanish pairings with explicit dialect tags per speaker.

  • 02

    Voseo, tuteo, and ustedeo register switches captured naturally per regional norm — not flattened into a single neutral form.

  • 03

    Spanglish code-switching from US-based and border-region bilingual speakers preserved at the utterance level.

  • 04

    Idiomatic phrases (modismos), regional slang (jerga), and rapid-fire interjections tagged for ASR robustness.
