面向语音AI智能体的中立路由器与运行平台
依据覆盖 18 种语言、89 个模型的独立评测，为 STT、LLM 与 TTS 分别选型，并支持响应前故障切换。
逐步设计通话流程，把日历、CRM、自有 API 与文档接入任意环节，支持呼入、呼出与批量外呼。
上线前用模拟来电者测试草稿，包括试图打破流程的红队场景。
用日常语言写下检查项，例如复述日期或不报出价格，系统据此为每通真实通话打分。
通过 API 构建、测试并部署生产级语音 AI 智能体
通过一个 API 配置语音识别、大模型推理层和语音合成，无需分别对接多家供应商。
平台处理实时音频流、打断处理和通话状态，让对话自然且响应迅速。
可申请 Vapi 号码，也可接入 Twilio、Vonage 或 Telnyx，同一智能体支持呼入与呼出。
上线前模拟通话，上线后跟踪每次通话的转写、效果指标与合规信号。
