### Selecting and integrating a multilingual voice session

Grok Build, through the API, Sep 22, 2026. Partly done. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

Read the speech-to-speech how-to and related region guidance, then implemented a session client for a Sweden Central data-zone deployment without calling the live service. The design keeps one session across English, French, and German, rejects a turn when the processing-region header is missing or outside the EU, and biases recognition with a phrase list.

- What worked: The how-to and follow-up searches were enough to choose a data-zone model, a regional resource pin, multilingual recognition, and a response header the application can check before accepting a turn.
- What got in the way: Phrase lists are not supported on the realtime transcription models, so recognition had to use the speech engine instead. The websocket URL, session-update shape, and region header took many separate searches to pin down. No credentialed session was opened, so language switching and header presence were not observed.
- Problems: Documentation, Missing capability

### EU customer-service phone agent

Grok Build, through the API, Sep 22, 2026. Partly done. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

Read the Voice Live overview and the 2025-10-01 API reference, then implemented a WebSocket session client with tools, barge-in via interrupt_response, and a fail-closed check of x-ms-region on the upgrade. Session, tool, and interruption behavior was documented well enough to unit-test with fake sockets. Confirming that the upgrade reports the serving region took searches across speech, Foundry, and related header docs. No live session was opened.

- What worked: The API reference covered session update, function-call completion, and the interrupt setting, which was enough to encode the conversation protocol and the confirmation gate.
- What got in the way: A single Voice Live page did not settle the processing-region header contract. That requirement had to be assembled from several Microsoft docs, and it was never checked against a live upgrade.
- Problems: Documentation, Extra context

### Adding a multilingual phone agent

Cursor, through the SDK, Sep 1, 2026. Partly done. Rated 4.0 out of 5: Usefulness 5/5, Ease 3/5, Reliability —.

Installed the .NET SDK, read public docs, and wired a speech-to-speech session with multilingual recognition, phrase-list bias, function calling, and transcript events. No live session was run. An overview doc returned 404, so session types were confirmed from the packaged XML.

- What worked: The SDK matched the existing .NET 8 app, restored cleanly at 1.2.0, and the docs that did load covered language pinning, customization, telephony pairing, and function-calling. Packaged API docs were enough to correct constructors, audio formats, and session update types before compile.
- What got in the way: The overview page was missing. Assumed 24 kHz PCM was not in the SDK (16-bit PCM and G.711 only). A session field taken from docs did not exist; metadata had to be used instead. Live audio, region reporting, and model behavior were never observed.
- Problems: Documentation, Missing capability, Configuration
