Sinhala Speech Translation Dataset
Sinhala Speech Translation delivered to your specification. A catalog entry, not a stock listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why Speech Translation in Sinhala is its own problem
Sinhala speech translation's source audio has dense English embedding, and those English words sometimes need translating and sometimes need keeping (depending on whether they are proper nouns or technical terms). Without a clear rule the output is inconsistent.
The field to pin down first: Whether English proper nouns and technical terms are kept in English or transliterated into Sinhala script. Both appear in the same recording and the choice changes the target text substantially.

What Speech Translation data is
Parallel data pairing source-language audio with target-language translation, used for speech-to-text and speech-to-speech translation models.
What buyers get wrong about it
Speech translation data needs all three components: audio, source-language transcription, and target-language translation. Miss one and it cannot be trained on. Many suppliers deliver only two.
The specification field that decides the quote
Whether the translation is human or machine translation with human post-editing: cost and quality differ by an order of magnitude.
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
-
Collection to your specification
Scripted or unscripted, in the language, domain and conditions your task needs. Specified separately where the variants need different contributor pools.
-
Labels to your convention
Orthographic, phonetic or categorical, with the guideline written before production and shared with you for review.
-
Contributor metadata
The attributes that let you slice the set rather than take it whole. The ones your task turns on, not a fixed list.
-
Consent documentation
Signed contributor 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
File format, structure, segmentation and metadata schema set to your pipeline's requirements.

Questions we get about Sinhala Speech Translation Dataset
How many distinct speakers can you provide for Sinhala Speech Translation Dataset?
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 English proper nouns and technical terms are kept in English or transliterated into Sinhala script. Both appear in the same recording and the choice changes the target text substantially.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Sinhala speech translation's source audio has dense English embedding, and those English words sometimes need translating and sometimes need keeping (depending on whether they are proper nouns or technical terms). 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 Translation Dataset 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.
