Dataset Structure

Data Instances

A typical data point comprises the audio signal iself, with additional labels like speaker id / session id (video_id) / language / gender etc.

Data Fields

• channel_id: YouTube channel ID from which speaker ID (spk_id) is derived.
• video_id: YouTube video ID, or session for speaker.
• segment_id: ID of chunk of video's audio, that passed filtration process.
• upload_date: Date time object representing the date when video was uploaded to YouTube.
• language: Language of the channel / speaker.
• gender: Gender of the channel / speaker.
• spk_id: Infered integer speaker ID from channel_id.
• spk_estim_age: Label of speaker age (not accurate) based on voice-based automatic age estimation & calibrated based on the upload_date of all videos for a given channel.
• spk_estim_age_mae: MAE of spk_estim_age (might be considered as confidence).
• audio: audio signal of a 4 seconds mp3 segment from channel_id/video_id
