Transcribed speech, accents and audio events.
2 data products and services
38,000 hours of transcribed two-speaker conversations in 22 Indian languages from consented contributors, with dialect, age band, environment and device metadata.
Speech recorded to your script, languages, demographics and acoustic conditions by consented contributors in India and South Asia, transcribed and delivered with consent records.
Speech and audio data includes recorded speech with transcripts, conversational audio, read prompts, accented and dialect speech, wake words and non-speech sound events. Teams building speech recognition, text-to-speech, voice assistants, call analytics and audio event detection buy it to cover new languages, accents, acoustic conditions and domains.
Most licensed speech is collected from paid contributors who record scripted prompts or conversations through a mobile app or phone line after giving informed consent for AI use. Transcripts are produced by trained transcribers with quality review. Some datasets come from licensed broadcasts or podcasts. Because voice recordings relate to identifiable people, they need careful handling, and providers should not sell voiceprints for identifying individuals.
Audio is delivered as WAV or FLAC files with transcripts in JSON or text, usually through cloud storage. Pricing is typically per hour of audio, varying with language rarity, transcription detail, speaker diversity, exclusivity and whether data is custom collected.
