Agent Metadata
Known Gotchas
- ⚠ Voice IDs are WellSaid-specific — agents must pre-fetch available voice list to get valid voice IDs before synthesis
- ⚠ Character limits per request — split long documents into segments before synthesis; stitch audio server-side
- ⚠ Synthesis is asynchronous for long content — agents must poll synthesis job status for completion
- ⚠ Audio format options limited to WAV/MP3 — transcode if other formats required in downstream workflow
- ⚠ WellSaid voices are licensed for specific use cases — review license terms before using in commercial products
