Czech speech dataset
We source Czech speech data to order: speaker recruitment, recording, transcription and annotation, delivered with the consent documentation that makes the dataset usable rather than merely delivered.
What makes Czech hard to collect
Czech distinguishes short and long vowels, and that distinction carries meaning, but everyday writing often drops the diacritics. Miss one mark in annotation and it is a different word.
This is the part that cannot be templated. Every language has a specific failure mode, and a project that does not plan for it produces data that looks complete and trains badly.

What we deliver for Czech
-
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 Czech
How many distinct speakers can you provide for Czech?
It depends on the specification and the timeline, and we will give a real number rather than a target. Speaker recruitment is usually the step that sets the schedule for Czech, so the answer to this question is also the answer to how long the project takes.
Can you annotate to a custom guideline?
Yes, and for Czech we would recommend it. The default conventions for this language leave several decisions open, and those decisions are exactly where annotators diverge. Send us your guideline, or we will draft one and you can review it before production.
Do you offer a sample before we commit?
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 before committing to a full run.
What if Czech is not something you can source?
Then we will tell you rather than take the order. We would rather decline a project than deliver something that does not meet the specification.
