About SpeechData.ai
SpeechData.ai is a commercial catalogue and collection service for conversational speech data used to build and evaluate ASR, TTS and other voice-AI systems. Its website lists 60 conversational datasets across 60 languages and dialects, totaling 73,000 audio hours from 7,250 speakers. Listings describe spontaneous two-person recordings, dual-channel audio, time-aligned human-verified transcripts, speaker metadata and consent documentation, with catalogue prices of USD 60–95 per audio hour. Buyers can request samples and commission additional collection to a brief. The provider also offers transcription and audio annotation. Typical buyers include teams sourcing speech for model training and evaluation. Dataset availability, licensing and final price depend on language, collection scope and the terms agreed for the project.
