Hi I’ve built production voice agents that answer calls, follow strict policy-only knowledge, and write back to CRMs/DBs with audit logs and safe fallbacks. Your biggest current blocker sounds like instruction drift (the agent stops obeying company rules) plus unpredictable per-call costs when every turn hits Gemini/ChatGPT. I can fix this by setting up a policy-locked orchestration layer: deterministic intent routing, cached “known answers,” and an audio-snippet library so repetitive/long responses play pre-recorded clips instead of TTS/LLM reads. For the remaining cases, I’ll use a retrieval + guardrails flow (Vertex/AI Studio or OpenAI + Whisper) with confidence scoring, strict tool schemas for DB writes, and an automatic handoff to your ticketing API when unsure. To support “self-teaching,” I’ll implement a feedback loop that turns unknown-call logs into new intents/KB entries with review gates, regression tests, and versioned prompts so learning never introduces hallucinations. You’ll receive source code, config/prompt packs, and a maintenance guide to retrain intents and update procedures without re-architecting anything. And I can help you so on. Thanks, Hercules

With a diverse range of skills in programming languages like Python, C, and C++, my proficiency spans across the multiple facets of your project requirements. My extensive experience in designing and implementing AI solutions using Python, along with my knowledge of AI Studio and OpenAI GPT, make me an ideal candidate to further develop your AI-voice agent. A major aspect to consider while creating an AI is its adaptability and proactiveness in learning from users' behavior and questions—a requirement that is already being practiced by your client. I can skillfully optimize the AI agent to automatically log unanswered questions for future learning and improvement. Moreover, I can design the AI agent to make intelligent decisions regarding when to hand off to a human agent using your ticketing API when confidence is low or explicitly requested by the caller.

@marvine02

Hello, I can build a fully voice-enabled AI agent using a low-latency speech pipeline (Whisper or Gemini STT), a custom intent router, and selective LLM calls—an approach I’ve used in several production phone-bot deployments for enterprise clients. Instead of calling GPT/Gemini for every step, I design hybrid architectures where the agent auto-generates and caches prerecorded audio for common responses, cutting runtime cost and improving response speed. I also have strong experience fixing partially built Vertex AI agents, tightening their instruction-following, grounding them strictly in company policies, and implementing continuous learning workflows using “unknown question” logs. For phone integration, I typically use real-time SIP/Twilio streaming with natural barge-in and confidence-based fallback to human support APIs. The final package includes the trained conversational layer, audio library, model/config files, and a simple retraining/update workflow your team can maintain independently. This setup consistently delivers predictable cost, sub-5-second replies, and zero hallucinations in live production environments. Please let me know if you require any detailed information. Waiting for your reply. I hope you respond to me. Thanks

@Gilsaydith

Hello, I understand you need an AI that follows strict company policies, handles calls naturally, uses prerecorded audio where cost-effective, self-learns from logged unknown queries, and integrates smoothly with your existing Google AI Studio setup. I have built similar conversational pipelines using GPT, Whisper, Vertex AI, and custom TTS/ASR stacks, ensuring predictable pricing, fast response times, and stable fallbacks when confidence is low. I can refine your current agent, correct instruction-following issues, and deliver a production-ready model with full phone integration, API handoff, and a clean maintenance guide your team can easily update. If you choose me, I will deliver a precise, reliable, and professional AI agent that meets all acceptance criteria and is ready for urgent deployment. I look forward to working with you.

@mayankinnovative

Hi there, I have 15+ years of experience in software development and have built multiple voice-driven AI agents using OpenAI, Google Vertex/AI Studio, Whisper pipelines, and low-latency telephony integrations. Your requirement is clear: a fully trained, cost-efficient voice agent that handles customer-support calls inside the app, follows strict company policies, and updates your database without human intervention. Here’s how I will implement this: • I will rebuild and fine-tune your existing Google AI Studio agent so it follows every instruction precisely, and eliminate hallucinations by converting policies/procedures into a structured, rule-based prompt framework. • Cost optimization: for long or repeated messages the agent will play pre-recorded audio instead of generating TTS every time. I will automate the audio recording pipeline so the system creates reusable clips automatically. • Real-time call handling using Whisper (or Vertex Speech) for fast, accurate speech-to-text and a neutral, professional TTS voice with <5s response time. • The agent will auto-learn: unknown queries will be logged, and you will get a clean file you can update and push back for incremental training. • Integration with your ticketing/database API so the bot can create, update or escalate tickets based on confidence thresholds. • Full source code + Let’s discuss your current system and next steps.
