Terms related to natural language processing · 3.6.18
speech synthesis
the generation of artificial speech
What this term settles
A governance lead borrows this meaning whenever speech synthesis appears in a risk assessment or an assurance argument. The borrowing is safe only if the artefact behind it matches the description.
Who it binds
The clause does not instruct anyone: it settles what speech synthesis means so that an instruction written elsewhere can be read the same way by both sides.
What to do in your practice
Add speech synthesis to the vocabulary register and to the onboarding pack. A term that is only in a PDF is not controlled; it is controlled when a new joiner can find it and a reviewer can test it.
Evidence an auditor or regulator asks for
- A controlled vocabulary entry for speech synthesis with the citation 3.6.18, an owner and a review date.An auditor can check that speech synthesis is controlled rather than assumed.
- A product description that names the language task and the input and output it handles. The row names speech synthesis.Shows speech synthesis in use in the artefact the firm relies on, not only in a glossary.
- An evaluation set with the language, the domain and the scoring rule. The record carries the speech synthesis entry and its date.The product description mixes the task with the model, so a change of model reads as a change of task. The gap is tested against speech synthesis.
Common gaps this page catches
- speech synthesis is used in the language task in the product description without a written definition, so two teams can mean different things.
- A supplier uses speech synthesis with a different boundary and nobody has recorded the difference.
What to prepare before the amendment lands
Take the next policy revision and replace the loose use of speech synthesis with the entry and its citation. Record the change in the vocabulary change log.
How to test it here
Take one live artefact rather than a template, find the sentence or field where speech synthesis is used, and put this page beside it. Record the answer, the artefact and the date, because that record is the evidence and a glossary entry on its own is only an intention.
What this page does not claim
The page does not reproduce the standard, certify the firm or predict the wording the amendment will use; it states speech synthesis at the claim level "definition" and stops where the public record stops.
