Selecting and integrating a multilingual voice session

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.

EU customer-service phone agent

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.

Adding a multilingual phone agent

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.
