Bangla speech dataset
We source Bangla speech data to order — speaker recruitment, recording, transcription and annotation, delivered with the consent documentation that makes the dataset usable rather than merely delivered.
What makes Bangla hard to collect
The Bangla of Bangladesh and of West Bengal in India has diverged in vocabulary and accent — the everyday word for the same meaning is often different. In search terms and annotation alike, bangla tracks real usage better than bengali.
This is the part that cannot be templated. Every language has a specific failure mode, and a project that does not plan for it produces data that looks complete and trains badly.

What we deliver for Bangla
-
Read and conversational speech
Scripted recording for TTS, and unscripted conversation for recognition. Specified separately because they need different speaker pools.
-
Transcription to your convention
Orthographic or phonetic, with the guideline written before production and shared with you for review.
-
Speaker metadata
Age band, gender, region and dialect background per file, so you can slice the dataset rather than take it whole.
-
Consent documentation
Signed speaker consent covering the intended use, plus collection methodology and the annotation guideline.
-
Pilot batch
A small batch first, which you can reject. Misalignments surface after a few hours rather than at delivery.
-
Delivery in your format
Audio format, sampling rate, segmentation length and metadata schema set to your pipeline's requirements.

Questions we get about Bangla
How many distinct speakers can you provide for Bangla?
It depends on the specification and the timeline, and we will give a real number rather than a target. Speaker recruitment is usually the step that sets the schedule for Bangla, so the answer to this question is also the answer to how long the project takes.
Can you annotate to a custom guideline?
Yes, and for Bangla we would recommend it. The default conventions for this language leave several decisions open, and those decisions are exactly where annotators diverge. Send us your guideline, or we will draft one and you can review it before production.
Do you offer a sample before we commit?
Yes. Select a free sample in the request form and describe what you need. A pilot batch is the cheapest way to establish whether the quality bar is reachable before committing to a full run.
What if Bangla is not something you can source?
Then we will tell you rather than take the order. We would rather decline a project than deliver something that does not meet the specification.
