### [Gemma 4 for Telephony: I Replaced Two AI Models With One in My Voice Phone Agent — Until I Switched to Chinese](https://wengjiyao.hashnode.dev/gemma-4-for-telephony-i-replaced-two-ai-models-with-one-in-my-voice-phone-agent-until-i-switched-to-chinese?utm_source=hashnode&utm_medium=feed)

I replaced faster-whisper + Gemma 4 with a single multimodal model that hears callers directly. 100% reply accuracy in English, 93% in French, 0% in Chinese. Benchmark data, code, and the architecture change for a SIP phone agent.
