Turkish Speech Translation Dataset
Turkish speech translation 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 translation in Turkish is its own problem
Turkish long words make translation alignment difficult — one long Turkish word can correspond to several words in the target language, so word-level alignment is not one-to-one. The alignment granularity has to be fixed in advance, or the delivered format cannot be used for training.
The field to pin down first: State the alignment granularity (sentence / phrase / word level); word-level alignment needs stated rules for many-to-many cases.

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 Turkish demands
Turkish is an agglutinative language: one root can carry a long chain of suffixes, so the word list explodes. Istanbul and eastern accents also differ noticeably — if speaker origin is not recorded clearly, model generalization suffers.
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 Turkish Speech Translation
How many distinct speakers can you provide for Turkish Speech Translation?
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. State the alignment granularity (sentence / phrase / word level); word-level alignment needs stated rules for many-to-many cases.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Turkish long words make translation alignment difficult — one long Turkish word can correspond to several words in the target language, so word-level alignment is not one-to-one. 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 Turkish Speech Translation 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.
