Global Conversational Audio Dataset 515,849 Hours Across 100 Languages

The Global Conversational Audio Dataset from Verbalscripts Transcription LLC provides access to a large multilingual conversational speech catalog covering 515,849 available audio hours across 100 languages. The dataset is designed for AI teams building ASR systems, speech-to-text models, multilingual LLM voice workflows, speaker diarization systems, language identification models, voice assistants, and speech analytics platforms.

This listing represents a catalog-based commercial data product. The uploaded sample file is a preview catalog only and is not the full dataset. The listed price represents a starting licensed delivery package, not the full 515,849-hour corpus. Final pricing depends on selected languages, number of audio hours, enrichment files, delivery format, and licensing scope.

Available data may include conversational audio files and related enrichment layers depending on the licensed subset. Supported enrichment may include mixed-down audio, speaker-separated stems where available, transcript and diarization files, word-level transcript data where available, language metadata, regional metadata, gender detection metadata, conversation summaries, sentiment analysis, and structured catalog fields.

Files can be delivered in formats such as WAV, MP3, JSON, CSV, TXT, ZIP, or another agreed structure based on buyer requirements.

The full catalog covers 100 languages across global regions including Africa, Asia, Europe, the Americas, the Middle East, and Oceania. Coverage includes major global languages such as English, Chinese, Hindi, Spanish, Arabic, French, Portuguese, and Russian, as well as regional and lower-resource languages such as Amharic, Hausa, Yoruba, Swahili, Somali, Lingala, Tibetan, Khmer, Lao, Pashto, Uzbek, Nepali, and others.

The exact geography breakdown, available hours, metadata fields, and enrichment layers vary by language and subset. A buyer may request a custom subset by language, region, number of hours, use case, file format, or annotation requirement.

The data is sourced through a combination of vetted data contributors, approved data collection partners, and rights-cleared supplier relationships. Collection methods vary by language and subset, but may include contributor-recorded conversational speech, language-specific audio collection projects, licensed conversational audio libraries, and approved speech-data sourcing programs.

Data is prepared for approved commercial AI and machine learning use cases. The collection period varies by subset, language, and supplier source. Collection-period details can be provided during buyer due diligence for the specific subset being requested.

Consent, Legal Basis, and Rights Chain

Available datasets are intended to be licensed only where there is an appropriate legal basis for commercial AI or machine learning use. Depending on the selected subset, this may be supported by contributor consent, rights-holder authorization, supplier license agreements, project-specific collection terms, or commercial data licensing arrangements.

Verbalscripts Transcription LLC does not publicly expose restricted source documentation on the marketplace listing. However, provenance, consent, licensing, permitted-use, and rights-chain documentation can be provided during qualified buyer due diligence or upon request, subject to confidentiality and the specific dataset being licensed.

This dataset may be used for AI training, model evaluation, ASR development, speech-to-text workflows, diarization benchmarking, voice assistant development, multilingual speech analytics, and LLM-related speech workflows, subject to the final license agreement.

The licensed data itself may not be resold, redistributed, published, sublicensed, or shared outside the buyer’s licensed environment unless expressly permitted in writing.

Full dataset delivery is handled through secure custom delivery after purchase or after a buyer-specific license agreement is completed. Delivery size depends on selected languages, number of hours, audio format, transcript format, and enrichment files. The platform sample file is only a preview catalog and should not be interpreted as the full dataset size.

The listed price of GBP 950 is a starter licensed delivery package covering up to 25 selected audio hours from this catalog, subject to language availability, licensing scope, enrichment requirements, and delivery format.
