What is Code-Switching Speech?
Speech that mixes two or more languages inside a single utterance — Hinglish, Spanglish, Taglish — used for recognition in real spoken settings.
What buyers get wrong
The switch point is the hard part — where language A gives way to B inside a sentence, different annotators can place it several words apart. The guideline has to be fixed before annotation starts.
The specification detail that decides everything
Whether annotation marks word-level switch points or only tags the language of the whole utterance — the workload differs by a multiple.
This is the line item that most often separates a dataset that works from one that gets re-ordered. It belongs in the specification before production starts, not in the delivery review.
How we source code-switching speech
We do not hold inventory in this category. A requirement comes in, we match it to a producer who can meet the specification, and we agree the quality bar with both sides before recording begins. A pilot batch goes first so misalignments surface early.

Questions about code-switching speech
Do you have code-switching speech available now?
No — we do not hold inventory. Everything is produced against a specification. That means the timeline starts when the spec is agreed rather than immediately, and it also means the data matches your requirement instead of approximately matching something already built.
Can this be combined with other categories in one delivery?
Yes, and it is common. A single specification can cover several categories across several languages, with one pilot batch and one quality bar. It usually reduces total cost because speaker recruitment and project setup are shared.
What does the consent documentation cover?
Signed speaker consent stating the intended use, the collection methodology, and the annotation guideline the data was produced under. For projects involving EU data subjects the chain is built to satisfy GDPR, including the transfer mechanism.
