What is Conversational Speech?

Speech from natural conversation between two or more people, on open or semi-structured topics, used for conversational AI, voice assistants, and small talk models.

What buyers get wrong

Natural conversation is full of overlapping speech, interruptions, particles, and laughter. Whether to keep these "messy" parts is the first thing to lock down on a project like this.

The specification detail that decides everything

Whether overlapping speech is kept or split — the two outputs cannot be mixed in a single delivery batch.

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 conversational 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 conversational speech

Do you have conversational 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.
