Sinhala Speech Commands Dataset
Sinhala speech commands 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 speech commands in Sinhala is its own problem
Sinhala speakers naturally embed English command words (play, stop) when talking to a device, and how often they use them differs a lot between city and countryside. If the word list does not cover that part, the real wake rate comes in noticeably below the test result.
The field to pin down first: English loanword entries get their own section, with the urban and rural speaker distribution stated.

What speech commands data is
Targeted recordings of short command words or phrases, usually with many speakers reading each entry several times over, used for wake words and on-device command recognition.
What buyers get wrong about it
What buyers consistently underestimate is the repetition count — a single command entry needs at least a few dozen distinct speakers, each reading it multiple times, to cover pronunciation variation.
The specification field that decides the quote
Once the word list is locked it cannot change; adding words midway means starting a new batch.
The language side: what Sinhala demands
Everyday Sinhala conversation is heavily embedded with English words, especially in the Colombo urban belt. Treating this mixed speech as pure Sinhala strips out high-frequency loanwords as if they were errors.
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 Sinhala Speech Commands
How many distinct speakers can you provide for Sinhala Speech Commands?
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. English loanword entries get their own section, with the urban and rural speaker distribution stated.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Sinhala speakers naturally embed English command words (play, stop) when talking to a device, and how often they use them differs a lot between city and countryside. 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 Sinhala Speech Commands 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.
