Hindi Voice Assistant Dataset
Hindi voice assistant 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 voice assistant in Hindi is its own problem
The core difficulty in Hindi voice-assistant data is the intent schema. Users express the same intent in Hindi, in English, or in Hinglish, and the classification schema has to accommodate all three — otherwise one intent gets split across different classes.
The field to pin down first: Whether the intent schema comes from you or is designed by us is the line the quote falls on, and it has to be settled first.

What voice assistant data is
Command and dialogue data for voice assistants, usually with intent annotation, covering the full chain from wake word to understanding to response.
What buyers get wrong about it
What buyers actually need is intent plus slot annotation, not just audio and transcription. The intent taxonomy has to align with the schema the buyer already runs.
The specification field that decides the quote
Whether the intent schema comes from the buyer or is designed by us — this is the dividing line in the quote.
The language side: what Hindi demands
Hindi and Urdu are mutually intelligible at the spoken level, but one is written in Devanagari and the other in Perso-Arabic script. Which script a recording is transcribed into directly determines whether the data can feed a model targeting Urdu.
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 Hindi Voice Assistant
How many distinct speakers can you provide for Hindi Voice Assistant?
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. Whether the intent schema comes from you or is designed by us is the line the quote falls on, and it has to be settled first.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. The core difficulty in Hindi voice-assistant data is the intent schema. 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 Hindi Voice Assistant 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.
