Free Punjabi speech data sample
Thirty minutes of Punjabi audio, recorded to your specification with transcripts and full metadata, at no cost. It exists so you can judge us on files rather than on claims.
- Sample size
- ~30 minutes
- Cost
- Free
- Turnaround
- 5-8 working days
- Formats
- WAV 48 kHz + transcript + metadata
What the sample contains
- Punjabi audio from at least four speakers with a mixed gender and age spread
- Coverage of Majhi (standard), Malwai, Doabi where your spec calls for dialect breadth
- Verbatim transcripts in Gurmukhi, with a romanised parallel transcript on request
- Per-file metadata: speaker ID, age band, gender, district, device, environment and SNR
- A short QA report showing how the files were checked before they were sent
How to specify it
| Decision | Options | Default if you do not say |
|---|---|---|
| Speech type | Scripted / spontaneous / conversational / telephony | Scripted plus a spontaneous block |
| Environment | Studio / quiet room / field / call path | Studio and quiet room, split |
| Sample rate | 48 kHz, 16 kHz, 8 kHz | 48 kHz mastered, 16 kHz derived |
| Dialects | Majhi (standard), Malwai, Doabi | Standard variety plus one regional |
| Annotation | Verbatim / timestamps / speaker turns / event tags | Verbatim with timestamps |
The sample is only useful if it looks like the data you would actually buy. Send the spec you would put in a purchase order and we record against that.
What to test it against
- Run it through your existing ASR or TTS pipeline and read the error breakdown by speaker and dialect
- Check how Punjabi code-mixing is transcribed: Punjabi speech mixes Hindi and English freely, with strong diaspora influence in urban registers.
- Check the transcription convention against your tokeniser — Tone is unrepresented in text, so pronunciation lexicons must be built from audio, not from spelling is the usual failure point
- Confirm the metadata is complete enough to filter and stratify by
What a Punjabi sample usually exposes
Punjabi has roughly 33 million speakers across Punjab, Haryana, Delhi, and models trained on generic multilingual data typically fail on the same things each time.
Tonal variation is essentially unmodelled in public Punjabi data, and Malwai/Doabi rural speech is scarce.
- Phonetics your acoustic model may not have seen: Punjabi is tonal: high, low and level tones distinguish words, and tone is not marked in Gurmukhi orthography
- Utterance types worth sampling separately: Minimal-pair tone elicitation sets, Agricultural and rural-finance domain conversation, Spontaneous conversation across Majha, Malwa and Doaba
- Recording geography in the sample: Amritsar, Ludhiana, Jalandhar
What happens after
Nothing automatic. If the sample works, we scope the full build against the same specification and quote a fixed price. If it does not, tell us what failed — that feedback is more useful to us than a polite no.
Cover all three historic regions (Majha, Malwa, Doaba); tone realisation differs measurably between them.
Frequently asked
Is the Punjabi sample really free?
Yes. There is no charge and no obligation. We cap it at roughly 30 minutes because that is enough to judge quality without becoming an unpaid production run.
Can we use the sample data commercially?
The sample is licensed for evaluation. Full commercial rights and IP transfer come with a paid delivery, including a paid pilot.
How long does it take?
Five to eight working days from an agreed specification, depending on how narrow the speaker cohort is.
Can we specify our own script?
Yes. Send your prompts, wake words or domain vocabulary and we record those instead of our standard set.
