透過 API 打造、測試並部署正式環境的語音 AI 代理
用一個 API 設定語音辨識、大型語言模型推理層與語音合成，不必分別串接多家供應商。
平台處理即時音訊串流、插話處理與通話狀態，讓對話自然且反應迅速。
可申請 Vapi 號碼，也能串接 Twilio、Vonage 或 Telnyx，同一個代理支援來電與去電。
上線前模擬通話，上線後追蹤每通電話的逐字稿、成效指標與合規訊號。

Abstracts speech-to-text, text-to-speech and LLM calls so you can swap vendors such as different STT, TTS and language model providers without rewriting your call flow.
Handles inbound and outbound phone calls with number provisioning, call creation, recording retrieval and CDR-style usage endpoints exposed through a documented REST API.
Register webhooks and self-contained actions so an agent can look things up, transfer a caller, or trigger work in your backend mid-conversation.
Supports streaming or turn-based conversation modes, endpointing and emotion tracking, plus browser and meeting-based interfaces beyond pure telephony.
專項更強Provides raw frontier language models and real-time multimodal capabilities, requiring custom scaffolding compared to Vapi's voice workflows.
專項更強Offers developer access to Gemini's powerful multimodal APIs, but lacks out-of-the-box telephony voice agent pipelines.
