Free Telugu speech data sample
Thirty minutes of Telugu 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
- Telugu audio from at least four speakers with a mixed gender and age spread
- Coverage of Telangana, Coastal Andhra (Godavari), Rayalaseema where your spec calls for dialect breadth
- Verbatim transcripts in Telugu, 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 | Telangana, Coastal Andhra (Godavari), Rayalaseema | 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 Telugu code-mixing is transcribed: Hyderabad speech mixes Telugu, Urdu/Deccani, Hindi and English. A Telugu dataset for Hyderabad deployment must include Urdu-origin vocabulary.
- Check the transcription convention against your tokeniser — Telangana forms normalised to Coastal Andhra standard is the usual failure point
- Confirm the metadata is complete enough to filter and stratify by
What a Telugu sample usually exposes
Telugu has roughly 96 million speakers across Andhra Pradesh, Telangana, parts of Karnataka and Odisha, and models trained on generic multilingual data typically fail on the same things each time.
Coastal Andhra read speech dominates. Telangana rural and Rayalaseema speech is thin, despite Hyderabad being the largest deployment market.
- Phonetics your acoustic model may not have seen: Vowel-length contrasts are phonemic and short/long confusion changes meaning outright
- Utterance types worth sampling separately: Region-tagged spontaneous conversation across all four dialect zones, Banking, agriculture and government-service domain prompts, Deccani-influenced Hyderabadi Telugu sessions
- Recording geography in the sample: Hyderabad, Vijayawada, Visakhapatnam
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.
Split cohorts explicitly between Telangana and Andhra Pradesh and tag every speaker; models trained without the tag cannot be evaluated per region.
Frequently asked
Is the Telugu 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.
