Indian Voice Integration for AI Calls

I am building an AI-driven calling solution on top of the OpenAI stack and need authentic Indian voices—both male and female—seamlessly integrated into the pipeline. The system will handle real-time customer service conversations, so clarity, natural intonation, and low-latency streaming are non-negotiable. Here is what I need from you: • Source or generate high-quality male and female Indian TTS voices that meet OpenAI compatibility requirements (Whisper, GPT-4, or any Speech-to-Speech layer you prefer). • Wire those voices into my existing call flow (currently running through Twilio Voice) so that the AI can listen, reason, and respond in real time. • Optimise for conversational turns under one second, with graceful fall-backs if network jitter occurs. • Provide a simple demo number where I can call in, interact with the bot, and hear both voices switch contextually. • Hand over clean, well-documented code and deployment steps so my dev team can maintain the integration. Please submit a detailed project proposal outlining: – Your chosen TTS engine(s) or custom model pipeline. – How you will preserve regional accents without sounding robotic. – Expected latency benchmarks and how you will achieve them. – A timeline with milestones all the way to live pilot. – Any previous voice or telephony integrations that prove you can deliver. I am ready to move quickly once I see a solid, technically sound plan that demonstrates you understand customer service nuances and can bring these Indian voices to life within the OpenAI ecosystem.
