Broken link: /api-reference/endpoint/openapi-v1/speech-to-speech returns 404

[zeprogress]

The site navigation links to /api-reference/endpoint/openapi-v1/speech-to-speech (following the same URL pattern as the existing text-to-speech, speech-to-text, and voice-design endpoint pages), but the page returns a 404, and I don't see a matching path in openapi.json either.

Could you confirm:

1. Is a speech-to-speech (voice conversion) endpoint planned or in development?
2. If so, is there a rough timeline for when the docs page / endpoint will be published?

Thanks!
