Free Malayalam speech data sample
Thirty minutes of Malayalam 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
- Malayalam audio from at least four speakers with a mixed gender and age spread
- Coverage of Thiruvananthapuram, Kochi (central), Malabar / Kozhikode where your spec calls for dialect breadth
- Verbatim transcripts in Malayalam, 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 | Thiruvananthapuram, Kochi (central), Malabar / Kozhikode | 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 Malayalam code-mixing is transcribed: Manglish is standard in urban and professional speech, with heavy English noun and verb insertion.
- Check the transcription convention against your tokeniser — Old vs new script (chillu characters, Unicode normalisation) mixed within a dataset is the usual failure point
- Confirm the metadata is complete enough to filter and stratify by
What a Malayalam sample usually exposes
Malayalam has roughly 35 million speakers across Kerala, Lakshadweep, Puducherry (Mahe), and models trained on generic multilingual data typically fail on the same things each time.
Central Kerala news-reading dominates public data. Malabar and southern varieties, and fast conversational speech generally, are missing.
- Phonetics your acoustic model may not have seen: One of the most consonant-dense Indian languages; long geminates and clusters raise word error rates sharply
- Utterance types worth sampling separately: Fast spontaneous conversation with verbatim transcription, Read prompts covering geminates and clusters, Mappila Malayalam dialect sets from Kozhikode and Malappuram
- Recording geography in the sample: Kochi, Thiruvananthapuram, Kozhikode
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.
Budget higher transcription effort per audio hour for Malayalam than for Hindi; speech rate and morphology make it slower to annotate.
Frequently asked
Is the Malayalam 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.
