Assamese 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 Assamese, where assamese has the voiceless velar fricative /x/, unique among major indian languages and routinely mis-modelled.

What changes when the language is Assamese
The service specification stays constant across languages; the linguistics do not. For Assamese, three things drive the design of a voice recording programme.
- Assamese has the voiceless velar fricative /x/, unique among major Indian languages and routinely mis-modelled
- Dialect spread: Kamrupi, Goalparia, Upper Assam (Sibsagar standard), Barak Valley contact varieties
- Assamese speech mixes Hindi, English and Bengali, with substantial contact influence in Barak Valley and tea-garden communities.
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 |

Assamese cohort design
Expect longer fielding times and higher per-hour cost than for Hindi or Marathi; the speaker pool with transcription-grade literacy is smaller.
| Dimension | Typical split | Why it matters for Assamese |
|---|---|---|
| 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 Assamese forms that younger urban speakers have lost |
| Region | Assam / Arunachal Pradesh / parts of Nagaland and Meghalaya and others | Dialect spread across 4 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
Assamese-specific quality rules
- Bengali characters substituted for Assamese ৰ / ৱ
- Goalparia and Kamrupi forms standardised to Sibsagar Assamese
- Tea-garden community speech excluded because transcribers cannot handle it
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 Assamese voice recording engagement: 100 hours from 300 speakers, 50/50 gender, ages 18-45, spread across Guwahati, Jorhat, Dibrugarh, 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
Extremely low-resource. Almost no spontaneous Assamese speech data exists publicly, and non-standard dialects have none.
Frequently asked
How much does Assamese voice recording cost?
Priced per delivered hour or unit against a written spec. The cost drivers for Assamese are dialect spread, demographic narrowness and recording condition, in that order.
Which Assamese dialects are included?
By default Kamrupi, Goalparia, Upper Assam (Sibsagar standard), Barak Valley contact varieties and others, tagged per speaker. You can also commission a single-dialect corpus if you are targeting one region.
Can you deliver Assamese data in our format?
Yes. Unprocessed WAV masters is the default, but naming, schema and directory structure follow your pipeline.
How long does a Assamese programme take?
2-5 weeks depending on speaker count and city spread.
