Mandarin Full-Duplex Conversation Dataset

Marketplace

Native-speaker Mandarin Chinese conversations recorded in full-duplex stereo across mainland and overseas dialect regions.

Overview

Naturalistic, two-speaker Mandarin Chinese conversations captured at studio quality in full-duplex stereo. Pairs of native Mandarin Chinese speakers from mainland China, Taiwan, and the Chinese diaspora 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 Mandarin Chinese 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

    Mainland Putonghua and Taiwanese Mandarin pairings with per-utterance tone variation tagged — critical for Mandarin TTS training.

  • 02

    Chinglish code-switching, English loanwords, and modern Chinese internet slang ("yyds", "emo", "绝绝子") preserved verbatim.

  • 03

    Family-style group conversation rhythm with overlapping turn-taking, rapid topic shifts, and culturally specific honorifics.

  • 04

    Regional accent coverage spanning Beijing, Shanghai, Guangdong (Mandarin-speaking), Taipei, and the overseas Chinese diaspora.
