ALLCITY Network operates one of the largest commercially licensed multilingual audio datasets available for AI training - 2.8 million hours across 122 languages, with a premium 515K-hour conversational subset purpose-built for ASR, TTS, and voice model development.

Every asset ships fully enriched: transcripts, speaker diarization, audio quality scoring, sentiment analysis, topic classification, speaker metadata, and content summaries. This is JSONL production-ready training data, not raw audio.

Beyond the OTS library, ACN can collect and procure audio to custom specifications and offers human transcript verification as a service.
