I can build an AI-powered voice agent capable of handling real, end-to-end phone conversations for your SaaS platform, with natural speech, fast response times, and clean integration into your existing APIs. Using a proven stack (e.g. Twilio for telephony + Dialogflow CX / Lex / Azure Speech or an equivalent I’ve deployed before), the agent will answer inbound calls, guide callers through structured conversational flows, capture key data points, and intelligently escalate to a human when confidence or intent clarity drops. Outbound, scheduled follow-up calls can also be added using the same architecture. The system will be cloud-hosted with a clear separation of concerns: • Telephony layer (SIP / Twilio) • Speech & NLU layer (STT, intent, entities, TTS) • Business logic & orchestration layer It will integrate seamlessly with your REST APIs to fetch customer context, and will post call transcripts, summaries, and extracted entities back to your callback endpoints. Deliverables • Live phone number with a voice agent sustaining 5+ minute conversations • Clean, well-structured source code • API hooks for transcripts and entities • Setup documentation + short Loom walkthrough I can deliver a functional prototype within 2 weeks, followed by a polished production version within one month.
