Frequently Asked Questions
Opti Call utilizes a streaming acoustic-to-semantic pipeline. As the user speaks, our speech-to-text engine streams partial transcript tokens immediately to a speculative LLM inference engine, which streams phonemes into neural speech synthesis before the full sentence is finished.
Yes. Our full-duplex voice activity detection (VAD) instantly detects user interruption (barge-in), cuts off speech synthesis within 80 milliseconds, and pivots the conversation context naturally.
Our speech models are specifically trained on Indian conversational speech datasets. The agent can listen to Hinglish queries ('Mera EMI kitna hoga?') and reply naturally in the customer's preferred blend of Hindi and English.
We support SIP trunks, Twilio, Telnyx, Plivo, Exotel, Tata Tele, and custom PSTN gateways. You can use your existing verified caller IDs and outbound DID pools seamlessly.
Standard pilots can be live in under 24 hours. Simply upload your product FAQs and contact list, configure objection rules, and trigger the campaign from our web dashboard.
