Language detection

Language detection lets an AI agent recognize the caller's language and reply in it immediately, with no upfront "for English, press 2" menu. It relies on speech recognition and language models able to identify a tongue from a few phonemes and even track code-switching — a caller drifting from French into English mid-sentence is still understood.

The stakes go beyond technical polish in bilingual areas — Montreal, Brussels, border regions, tourist clienteles — and anywhere an English-speaking clientele calls a French-speaking business, or the reverse. A caller served in their own language from the first word stays on the line; a caller bounced to a language-selection menu already has a reason to hang up. The right implementation is invisible: the agent simply answers.
