# Pulse STT: European streaming Beta, redaction English/Hindi-only

**European streaming languages tagged Beta.** The 7 European codes on the streaming endpoint (`de`, `es`, `ru`, `it`, `fr`, `nl`, `pt`) now carry a Beta badge on the Pulse model card.

**Pre-recorded language list trimmed.** Removed `da`, `lv`, `et`, `mt` from the batch language table (not offered on batch). New counts: 22 pre-recorded, 31 total, 21 streaming unchanged. `multi-eu` aggregator now covers 17 European codes and is pre-recorded only.

**Redaction language scope.** `redact_pii` and `redact_pci` are supported on `language=en` and `language=hi` only. Set on other language codes, the API accepts the flag but does not reliably redact. Documented on the [Redaction](/models/speech-to-text/features/redaction) page and in the `stt-live-ws` spec.
