Built for
For teams training or testing speech models that have to cope with real Gujarati speech:

- Text-to-speech and voice synthesis prosody
- Voice agents and IVR for India
- Speaker diarization and turn-taking models
- Speech LLM and audio-understanding fine-tuning
Why conversational data?
Models trained on read speech lose accuracy on spontaneous audio, because hesitations, overlapping turns and natural speaking rates never made it into their training data. This dataset fills that gap for Gujarati. Our guide to conversational speech data explains why it matters.

FAQ
Frequently asked questions
What is in the Gujarati speech dataset?
500 hours of unscripted conversation between pairs of native speakers, 50 vetted speakers in all, recorded in India. Each conversation is delivered as dual-channel audio with a time-aligned transcript, speaker metadata (age, gender, region and recording device) and the consent records behind it.
What makes Gujarati hard for speech recognition?
Gujarati uses breathy vowels to distinguish meaning, and models trained on other languages struggle to hear them. It has a script of its own, and in conversation speakers mix in English and Hindi, above all for numbers, dates and technical terms.
Is the Gujarati dataset licensed for commercial use?
Yes. The license covers commercial training and evaluation of ASR, TTS and other voice AI models. Every speaker signed explicit consent to commercial use, and Spirelight shares the full consent records for your legal review.
What does the Gujarati speech dataset cost?
$65 per hour of audio. Buying the full dataset, or several languages together, qualifies for a volume discount: ask for a quote.
Can I check samples before I buy?
Yes. Request samples on this page and the Spirelight team emails representative audio, matching transcripts and the metadata schema within 48 hours, so your team can audit the data before committing.
