Ready-made Gujarati speech datasets

Availability is confirmed per enquiry. Some material can only be licensed within the consent scope the speakers originally agreed to, and we will not stretch that to close a sale.

• Consent scope: does it permit commercial model training, and by a third party?
• Dialect distribution: a corpus that is 90% one urban variety will not generalise across Gujarat, Daman & Diu, Dadra & Nagar Haveli
• Recording conditions: studio-only data underperforms badly on noisy deployments
• Transcription convention: Breathy vowels have no consistent orthographic marking will otherwise surface as tokenisation noise
• Overlap: check whether the corpus already sits in the public sets you trained on

Very little spontaneous Gujarati audio exists publicly; nearly all of it is Ahmedabad read speech.

This is usually the reason buyers move from licensing to commissioning: the free and cheap material covers the easy half of the language.

• Dialect spread across Standard (Amdavadi), Surti, Kathiyawadi, Kachchhi-influenced rather than a single prestige variety
• The phonetic contrasts that Gujarati models actually get wrong: Murmured (breathy-voiced) vowels are phonemic in Gujarati and are absent from most shared Indic acoustic models
• Code-mixed speech transcribed rather than discarded — Business and trade vocabulary is heavily English; Gujarati diaspora speech adds further English structure. Specify whether diaspora speakers are in or out of scope.
• Recording geography covering Ahmedabad, Surat, Vadodara, Rajkot, since dialect follows location
• Utterance types beyond read prompts: Trade, retail and logistics domain conversation, Read prompts covering murmured vowels, Surti and Kathiyawadi dialect sets

Surat and Rajkot recruitment is essential for dialect coverage; Ahmedabad-only cohorts sound uniform.
