Nepali Conversational Speech Dataset
Nepali conversational 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 conversational speech in Nepali is its own problem
The Nepali honorific system (तपाईं / तिमी / तँ) switches within a single conversation as topic and mood change — the same speaker addressing the same person may use honorifics through the first half and plain form in the second. That switching is genuine language behavior, and it is a challenge for annotation consistency.
The field to pin down first: Honorific forms are transcribed as spoken and never normalized, and the social relationship between the two speakers is annotated in the metadata.

What conversational speech data is
Speech from natural conversation between two or more people, on open or semi-structured topics, used for conversational AI, voice assistants, and small talk models.
What buyers get wrong about it
Natural conversation is full of overlapping speech, interruptions, particles, and laughter. Whether to keep these "messy" parts is the first thing to lock down on a project like this.
The specification field that decides the quote
Whether overlapping speech is kept or split — the two outputs cannot be mixed in a single delivery batch.
The language side: what Nepali demands
Usable Nepali speech data is surprisingly scarce, and the accent layers of speakers across borders (Nepal, Sikkim in India, Bhutan) are poorly mapped. Speaker metadata — nationality, home region, language of education — has to be recorded item by item.
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.
What arrives in a delivery
| Component | What it is |
|---|---|
| Audio files | Format, sampling rate and segmentation length set to your pipeline. Named to a convention you specify. |
| Transcription | Orthographic or phonetic, produced under a guideline you review before production starts. |
| Speaker metadata | Age band, gender, region and dialect background per file, plus a speaker identifier so the dataset can be sliced. |
| Recording conditions | Environment, device and, where relevant, measured signal-to-noise ratio per file. |
| Annotation guideline | The document the annotators worked from, so you can reproduce the conventions on your own data. |
| Consent records | Signed speaker consent covering your intended use, with the transfer mechanism addressed where required. |
| Collection methodology | How speakers were recruited, screened and scheduled — the part that tells you how biased the pool is. |
| Quality report | Pilot outcome, re-work log, and the annotator agreement figures where the task supports measuring them. |
Questions we get about Nepali Conversational Speech
How many distinct speakers can you provide for Nepali Conversational 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. Honorific forms are transcribed as spoken and never normalized, and the social relationship between the two speakers is annotated in the metadata.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. The Nepali honorific system (तपाईं / तिमी / तँ) switches within a single conversation as topic and mood change — the same speaker addressing the same person may use honorifics through the first half and plain form in the second. 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 Nepali Conversational 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.
