Re-voice the module the day the policy changes.

A training library is never finished. Compliance wording shifts, a product name changes, a module gets re-cut, and every edit means re-voicing a section. Metered pricing charges for that edit as if it were new work, so a living library is billed by how often it is corrected.

a seat a month — re-voicing every module is included

The arithmetic of revision

An onboarding or compliance course is hundreds of short modules, and each module is a loop over requests of up to 2,000 characters. On an unmetered seat that loop costs the same whether it runs once or a hundred times, so re-rendering a corrected paragraph is free rather than a budget line.

The effect on an L&D team is that a policy change becomes a same-day edit. You re-voice the affected section, ship it, and move on, instead of batching corrections until they are worth the meter. Length and revision frequency stop being the things you ration.

What a training library needs from the voice

Instant voice cloning fixes one narrator across the whole catalogue, so a re-voiced module sits inside the course without a seam.
23 languages let a single script ship to every region from the same seat, and a translated module re-voices on the same terms as the original.
A pronunciation dictionary settles product names, acronyms and legal terms once per request, so the same word is said the same way in every module.
Break tags place the beat between a rule and its example, so a dense compliance passage reads as instruction rather than a run-on.

Notes — an engineer's checklist

01A policy changed and only one section is affected — do I re-render the whole course?

No. Each module is its own loop over requests, so you re-voice only the changed section against the same reference voice, and the rest of the library is untouched.

02How do I keep one narrator across a catalogue built over years?

The voice is a request parameter conditioned on a fixed reference, so a module voiced today matches one voiced last year with no drift between sessions.

03Does re-voicing hundreds of modules cost more than voicing them once?

No. The seat is flat at $150 a month and unmetered, so the cost does not move with how many characters you render or how often you revise them.
