API で本番運用レベルの音声 AI エージェントを構築・テスト・配備
音声認識、LLM 推論層、音声合成を 1 つの API で設定でき、複数ベンダーを個別に統合する必要がありません。
リアルタイム音声ストリーミング、割り込み処理、通話状態をプラットフォームが管理し、自然で応答性の高い会話を実現します。
Vapi の電話番号を発行でき、Twilio、Vonage、Telnyx の持ち込みにも対応。同一エージェントで着信と発信の両方を扱えます。
公開前に通話をシミュレーションし、公開後は全通話の文字起こし、有効性指標、コンプライアンス信号を追跡できます。

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.
特化型Provides raw frontier language models and real-time multimodal capabilities, requiring custom scaffolding compared to Vapi's voice workflows.
