StableVoice
The service's listing describes it this way: Mint a browser recording URL for a StableUpload slot. The recordee speaks optional suggestedText; StableVoice transcodes the audio to MP3 and uploads it to the slot. Use the slot publicUrl as /api/speech referenceAudioUrl. Pass uploadUrlExpiresAt as expiresAt so the recording URL cannot outlive the upload. Website

The page link uses the service's site when we have one, and the payee address otherwise.
