Bangla Call Center Speech Dataset
Bangla call center speech sourced to your specification — no inventory, no fixed listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why call center speech in Bangla is its own problem
Bangladesh (Dhaka) and the Indian state of West Bengal are two independent markets: the same meaning takes a different everyday word, and the business processes and product vocabulary differ too. In both search and annotation, "Bangla" is closer to how people actually say it than "Bengali", but buyers in the two places do not understand "standard Bangla" the same way.
The field to pin down first: Specify which market is the baseline (Dhaka / Kolkata), and deliver in separate regional batches rather than one mixed batch.

What call center speech data is
Recorded customer-service calls, real or simulated, capturing both the agent and the caller side, used for call center QC, intent recognition, and dialogue systems.
What buyers get wrong about it
Compliance is what buyers fear most — call recordings involve personal data and recording consent, and the source has to be able to produce a consent provenance. This is also why we only do simulated collection and never work from intercepted real calls.
The specification field that decides the quote
Two-channel separated (agent and caller on separate tracks) or single-channel mixed — this directly determines how the data is annotated and how models are trained on it, and it has to be decided when the order is placed.
The language side: what Bangla demands
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.
What we can put in this delivery
-
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 Call Center Speech
How many distinct speakers can you provide for Bangla Call Center Speech?
It depends on the specification and the timeline, and we will give a real number rather than a target. For this pairing, speaker recruitment is usually the step that sets the schedule. Specify which market is the baseline (Dhaka / Kolkata), and deliver in separate regional batches rather than one mixed batch.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Bangladesh (Dhaka) and the Indian state of West Bengal are two independent markets: the same meaning takes a different everyday word, and the business processes and product vocabulary differ too. That is exactly the kind of decision a default guideline leaves open, and it is where annotators diverge. Send us your guideline, or we will draft one and you can review it before production starts.
Do you offer a sample before we commit to a full run?
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 for Bangla Call Center Speech before committing to the full volume.
Is the data licensed or owned outright?
Licensing terms are set per project, so tell us how the model will be used and whether it will be distributed. Consent documentation travels with the data either way, and we do not handle medical or clinical data or recorded telephone calls.
