Gujarati Voice Recording for AI Training
Studio voice recording built for model training rather than broadcast: controlled acoustics, consistent mic distance, and reproducible session parameters across every speaker. This page covers how that works specifically for Gujarati, where murmured (breathy-voiced) vowels are phonemic in gujarati and are absent from most shared indic acoustic models.

What changes when the language is Gujarati
The service specification stays constant across languages; the linguistics do not. For Gujarati, three things drive the design of a voice recording programme.
- Murmured (breathy-voiced) vowels are phonemic in Gujarati and are absent from most shared Indic acoustic models
- Dialect spread: Standard (Amdavadi), Surti, Kathiyawadi, Kachchhi-influenced
- Business and trade vocabulary is heavily English; Gujarati diaspora speech adds further English structure. Specify whether diaspora speakers are in or out of scope.
Technical specification
| Parameter | Standard |
|---|---|
| Sample rate | 48 kHz |
| Bit depth | 24-bit |
| Microphone | Large-diaphragm condenser, fixed distance, pop filter |
| Room | Treated booth, RT60 under 0.3s |
| Processing | None. No compression, EQ, or noise reduction on delivered audio |
| Session length | 30-90 minutes per speaker, with breaks logged |
Gujarati cohort design
Surat and Rajkot recruitment is essential for dialect coverage; Ahmedabad-only cohorts sound uniform.
| Dimension | Typical split | Why it matters for Gujarati |
|---|---|---|
| Gender | 50 / 50 | Pitch range differences change acoustic model behaviour; unbalanced cohorts bias recognition |
| Age | 18-25: 30%, 26-40: 40%, 41-60: 30% | Older speakers retain conservative Gujarati forms that younger urban speakers have lost |
| Region | Gujarat / Daman & Diu / Dadra & Nagar Haveli and others | Dialect spread across 5 recognised varieties |
| Education | Mixed, including below-graduate | Prompt-reading fluency correlates with education and skews prosody |
| Condition | Studio / quiet room / field | Match the noise profile of your deployment |
Process
- Session template definition so every studio in the network records identically
- Speaker briefing and pronunciation calibration
- Take-level monitoring with immediate re-record on defect
- Per-session technical report
- Delivery with unprocessed masters
Gujarati-specific quality rules
- Breathy vowels have no consistent orthographic marking
- Kathiyawadi lexical items replaced with standard equivalents
- Numerals and currency in trade speech written inconsistently
Delivered audio is never processed. Training pipelines should see the raw capture so augmentation stays under your control.
Deliverables
- Unprocessed WAV masters
- Session logs
- Take-level metadata
- Speaker consent records
Worked example
A representative Gujarati voice recording engagement: 250 hours from 500 speakers, 50/50 gender, ages 18-45, spread across Ahmedabad, Surat, Vadodara, recorded to the specification above and delivered in WAV with a per-utterance manifest.
Timeline: 2-5 weeks depending on speaker count and city spread.
Where this data is missing today
Very little spontaneous Gujarati audio exists publicly; nearly all of it is Ahmedabad read speech.
Frequently asked
How much does Gujarati voice recording cost?
Priced per delivered hour or unit against a written spec. The cost drivers for Gujarati are dialect spread, demographic narrowness and recording condition, in that order.
Which Gujarati dialects are included?
By default Standard (Amdavadi), Surti, Kathiyawadi, Kachchhi-influenced and others, tagged per speaker. You can also commission a single-dialect corpus if you are targeting one region.
Can you deliver Gujarati data in our format?
Yes. Unprocessed WAV masters is the default, but naming, schema and directory structure follow your pipeline.
How long does a Gujarati programme take?
2-5 weeks depending on speaker count and city spread.
