Overview
Multilingual Podcast Audio Dataset (Single & Dual Channel)
Overview
This dataset is a large-scale multilingual podcast audio corpus designed for training and evaluating Automatic Speech Recognition (ASR), Speech-to-Text (STT), Speech AI, Voice AI, Conversational AI, Natural Language Processing (NLP), Generative AI, and Large Language Models (LLMs).
The corpus contains over 57,000 hours of podcast audio collected from diverse podcast formats, speakers, topics, and conversational styles. The dataset includes both single-channel and dual-channel recordings, enabling a wide range of speech processing, speaker modeling, transcription, and conversational AI applications.
The audio captures authentic human speech with natural accents, speaking styles, conversational dynamics, pauses, interruptions, emotional variation, and real-world recording conditions, making it suitable for enterprise AI development and research.

Dimensions summary
This listing carries a single pricing dimension: Product Access (Units), which grants subscribers access to the dataset at no charge. There are no tiers, instance sizes, or usage-based add-ons to compare. You subscribe once to unlock access. The dataset covers multilingual podcast audio in single and dual channel formats. Because pricing is free, there is nothing that scales with volume, language count, or usage. Access is uniform for all subscribers under this one dimension.
Top-of-mind questions for buyers
One unit grants subscriber access to the multilingual podcast audio dataset. This covers single and dual channel podcast speech recordings. Access is uniform for every subscriber. There is no per-hour, per-language, or per-recording metering tied to the unit.
No. Pricing is free under a single access dimension. Nothing scales with the number of languages, the volume of audio hours, or whether you use single or dual channel recordings. Your access stays the same no matter how much of the dataset you use.
You get podcast speech recordings in single and dual channel formats. Recordings carry metadata such as gender, age, industry, channel, dialect, and language. Delivery uses WAV or FLAC audio with JSON transcripts and a metadata file. Diarization files ship with dual channel audio.
